ADVERSE REACTIONS SECTION.

ADVERSE REACTIONS. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.Itraconazole has been associated with rare cases of serious hepatotoxicity, including liver failure and death. Some of these cases had neither pre-existing liver disease nor serious underlying medical condition. If clinical signs or symptoms develop that are consistent with liver disease, treatment should be discontinued and liver function testing performed. The risks and benefits of itraconazole use should be reassessed. (See WARNINGS: Hepatic Effects and PRECAUTIONS: Hepatotoxicity and Information for Patients.). Adverse Events in the Treatment of Systemic Fungal Infections. Adverse event data were derived from 602 patients treated for systemic fungal disease in U.S. clinical trials who were immunocompromised or receiving multiple concomitant medications. Treatment was discontinued in 10.5% of patients due to adverse events. The median duration before discontinuation of therapy was 81 days (range: to 776 days). The table lists adverse events reported by at least 1% of patients.Table 3:Clinical Trials of Systemic Fungal Infections: Adverse Events Occurring with an Incidence of Greater than or Equal to 1%Body System/Adverse EventIncidence (%) (N=602)Gastrointestinal Nausea11 Vomiting5 Diarrhea3 Abdominal Pain2 Anorexia1Body as Whole Edema4 Fatigue3 Fever3 Malaise1Skin and Appendages RashRash tends to occur more frequently in immunocompromised patients receiving immunosuppressive medications. 9Pruritus3Central/Peripheral Nervous System Headache4 Dizziness2Psychiatric Libido Decreased1 Somnolence1Cardiovascular Hypertension3Metabolic/Nutritional Hypokalemia2Urinary System Albuminuria1Liver and Biliary System Hepatic Function Abnormal3Reproductive System, MaleImpotence1Adverse events infrequently reported in all studies included constipation, gastritis, depression, insomnia, tinnitus, menstrual disorder, adrenal insufficiency, gynecomastia, and male breast pain..

Post-marketing Experience. Adverse drug reactions that have been first identified during post-marketing experience with itraconazole (all formulations) are listed in the table below. Because these reactions are reported voluntarily from population of uncertain size, reliably estimating their frequency or establishing causal relationship to drug exposure is not always possible.Table 6:Postmarketing Reports of Adverse Drug ReactionsBlood and Lymphatic System Disorders:Leukopenia, neutropenia, thrombocytopeniaImmune System Disorders:Anaphylaxis; anaphylactic, anaphylactoid and allergic reactions; serum sickness; angioneurotic edemaNervous System Disorders: Peripheral neuropathy, paresthesia, hypoesthesia, tremorEye Disorders:Visual disturbances, including vision blurred and diplopiaEar and Labyrinth Disorders:Transient or permanent hearing lossCardiac Disorders:Congestive heart failureRespiratory, Thoracic and Mediastinal Disorders:Pulmonary edema, dyspneaGastrointestinal Disorders:Pancreatitis, dysgeusiaHepatobiliary Disorders:Serious hepatotoxicity (including some cases of fatal acute liver failure), hepatitisSkin and Subcutaneous Tissue Disorders:Toxic epidermal necrolysis, Stevens-Johnson syndrome, acute generalized exanthematous pustulosis, erythema multiforme, exfoliative dermatitis, leukocytoclastic vasculitis, alopecia, photosensitivity, urticariaMusculoskeletal and Connective Tissue Disorders:ArthralgiaRenal and Urinary Disorders:Urinary incontinence, pollakiuriaReproductive System and Breast Disorders:Erectile dysfunctionGeneral Disorders and Administration Site Conditions:Peripheral edemaInvestigations:Blood creatine phosphokinase increasedThere is limited information on the use of itraconazole during pregnancy.

(See CLINICAL PHARMACOLOGY: Special Populations, CONTRAINDICATIONS, WARNINGS, and PRECAUTIONS: Drug Interactions for more information.).

BOXED WARNING SECTION.

BOXED WARNING. Congestive Heart Failure, Cardiac Effects and Drug Interactions. Itraconazole Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or history of CHF. If signs or symptoms of congestive heart failure occur during administration of Itraconazole Capsules, discontinue administration. When itraconazole was administered intravenously to dogs and healthy human volunteers, negative inotropic effects were seen. (See CONTRAINDICATIONS, WARNINGS, PRECAUTIONS. Drug Interactions, ADVERSE REACTIONS: Post-marketing Experience, and CLINICAL PHARMACOLOGY: Special Populations for more information.). Drug Interactions. Coadministration of the following drugs are contraindicated with Itraconazole Capsules: methadone, disopyramide, dofetilide, dronedarone, quinidine, isavuconazole, ergot alkaloids (such as dihydroergotamine, ergometrine (ergonovine), ergotamine, methylergometrine (methylergonovine)), irinotecan, lurasidone, oral midazolam, pimozide, triazolam, felodipine, nisoldipine, ivabradine, ranolazine, eplerenone, cisapride, naloxegol, lomitapide, lovastatin, simvastatin, avanafil, ticagrelor. In addition, coadministration with colchicine, fesoterodine and solifenacin is contraindicated in subjects with varying degrees of renal or hepatic impairment, and coadministration with eliglustat is contraindicated in subjects that are poor or intermediate metabolizers of CYP2D6 and in subjects taking strong or moderate CYP2D6 inhibitors. See PRECAUTIONS: Drug Interactions Section for specific examples. Coadministration with itraconazole can cause elevated plasma concentrations of these drugs and may increase or prolong both the pharmacologic effects and/or adverse reactions to these drugs. For example, increased plasma concentrations of some of these drugs can lead to QT prolongation and ventricular tachyarrhythmias including occurrences of torsades de pointes, potentially fatal arrhythmia. See CONTRAINDICATIONS and WARNINGS Sections, and PRECAUTIONS: Drug Interactions Section for specific examples.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

Carcinogenesis, Mutagenesis, and Impairment of Fertility. Itraconazole showed no evidence of carcinogenicity potential in mice treated orally for 23 months at dosage levels up to 80 mg/kg/day (approximately 10 times the maximum recommended human dose [MRHD]). Male rats treated with 25 mg/kg/day (3.1 times the MRHD) had slightly increased incidence of soft tissue sarcoma. These sarcomas may have been consequence of hypercholesterolemia, which is response of rats, but not dogs or humans, to chronic itraconazole administration. Female rats treated with 50 mg/kg/day (6.25 times the MRHD) had an increased incidence of squamous cell carcinoma of the lung (2/50) as compared to the untreated group. Although the occurrence of squamous cell carcinoma in the lung is extremely uncommon in untreated rats, the increase in this study was not statistically significant.Itraconazole produced no mutagenic effects when assayed in DNA repair test (unscheduled DNA synthesis) in primary rat hepatocytes, in Ames tests with Salmonella typhimurium (6 strains) and Escherichia coli, in the mouse lymphoma gene mutation tests, in sex-linked recessive lethal mutation (Drosophila melanogaster) test, in chromosome aberration tests in human lymphocytes, in cell transformation test with C3H/10T 1/2 C18 mouse embryo fibroblasts cells, in dominant lethal mutation test in male and female mice, and in micronucleus tests in mice and rats.Itraconazole did not affect the fertility of male or female rats treated orally with dosage levels of up to 40 mg/kg/day (5 times the MRHD), even though parental toxicity was present at this dosage level. More severe signs of parental toxicity, including death, were present in the next higher dosage level, 160 mg/kg/day (20 times the MRHD).

CLINICAL PHARMACOLOGY SECTION.

CLINICAL PHARMACOLOGY. Pharmacokinetics and Metabolism. General Pharmacokinetic Characteristics. Peak plasma concentrations of itraconazole are reached within to hours following oral administration. As consequence of non-linear pharmacokinetics, itraconazole accumulates in plasma during multiple dosing. Steady-state concentrations are generally reached within about 15 days, with Cmax values of 0.5 ug/mL, 1.1 ug/mL and 2.0 ug/mL after oral administration of 100 mg once daily, 200 mg once daily and 200 mg b.i.d., respectively. The terminal half-life of itraconazole generally ranges from 16 to 28 hours after single dose and increases to 34 to 42 hours with repeated dosing. Once treatment is stopped, itraconazole plasma concentrations decrease to an almost undetectable concentration within to 14 days, depending on the dose and duration of treatment. Itraconazole mean total plasma clearance following intravenous administration is 278 mL/min. Itraconazole clearance decreases at higher doses due to saturable hepatic metabolism.. Absorption. Itraconazole is rapidly absorbed after oral administration. Peak plasma concentrations of itraconazole are reached within to hours following an oral capsule dose. The observed absolute oral bioavailability of itraconazole is about 55%.The oral bioavailability of itraconazole is maximal when Itraconazole Capsules are taken immediately after full meal.Absorption of itraconazole capsules is reduced in subjects with reduced gastric acidity, such as subjects taking medications known as gastric acid secretion suppressors (e.g., H2-receptor antagonists, proton pump inhibitors) or subjects with achlorhydria caused by certain diseases. (See PRECAUTIONS: Drug Interactions.) Absorption of itraconazole under fasted conditions in these subjects is increased when Itraconazole Capsules are administered with an acidic beverage (such as non-diet cola). When Itraconazole Capsules were administered as single 200-mg dose under fasted conditions with non-diet cola after ranitidine pretreatment, H2-receptor antagonist, itraconazole absorption was comparable to that observed when Itraconazole Capsules were administered alone. (See PRECAUTIONS: Drug Interactions.)Itraconazole exposure is lower with the Capsule formulation than with the Oral Solution when the same dose of drug is given. (See WARNINGS). Distribution. Most of the itraconazole in plasma is bound to protein (99.8%), with albumin being the main binding component (99.6% for the hydroxy-metabolite). It has also marked affinity for lipids. Only 0.2% of the itraconazole in plasma is present as free drug. Itraconazole is distributed in large apparent volume in the body (>700 L), suggesting extensive distribution into tissues. Concentrations in lung, kidney, liver, bone, stomach, spleen and muscle were found to be two to three times higher than corresponding concentrations in plasma, and the uptake into keratinous tissues, skin in particular, up to four times higher. Concentrations in the cerebrospinal fluid are much lower than in plasma.. Metabolism. Itraconazole is extensively metabolized by the liver into large number of metabolites. In vitro studies have shown that CYP3A4 is the major enzyme involved in the metabolism of itraconazole. The main metabolite is hydroxy-itraconazole, which has in vitro antifungal activity comparable to itraconazole; trough plasma concentrations of this metabolite are about twice those of itraconazole.. Excretion. Itraconazole is excreted mainly as inactive metabolites in urine (35%) and in feces (54%) within one week of an oral solution dose. Renal excretion of itraconazole and the active metabolite hydroxy-itraconazole account for less than 1% of an intravenous dose. Based on an oral radiolabeled dose, fecal excretion of unchanged drug ranges from 3% to 18% of the dose.As re-distribution of itraconazole from keratinous tissues appears to be negligible, elimination of itraconazole from these tissues is related to epidermal regeneration. Contrary to plasma, the concentration in skin persists for to weeks after discontinuation of 4-week treatment and in nail keratin where itraconazole can be detected as early as week after start of treatment for at least six months after the end of 3-month treatment period.. Special Populations. Renal Impairment. Limited data are available on the use of oral itraconazole in patients with renal impairment. pharmacokinetic study using single 200-mg oral dose of itraconazole was conducted in three groups of patients with renal impairment (uremia: n=7; hemodialysis: n=7; and continuous ambulatory peritoneal dialysis: n=5). In uremic subjects with mean creatinine clearance of 13 mL/min. 1.73 m2, the exposure, based on AUC, was slightly reduced compared with normal population parameters. This study did not demonstrate any significant effect of hemodialysis or continuous ambulatory peritoneal dialysis on the pharmacokinetics of itraconazole (Tmax, Cmax, and AUC0-8h). Plasma concentration-versus-time profiles showed wide intersubject variation in all three groups. After single intravenous dose, the mean terminal half-lives of itraconazole in patients with mild (defined in this study as CrCl 50-79 mL/min), moderate (defined in this study as CrCl 20-49 mL/min), and severe renal impairment (defined in this study as CrCl <20 mL/min) were similar to that in healthy subjects (range of means 42-49 hours vs 48 hours in renally impaired patients and healthy subjects, respectively). Overall exposure to itraconazole, based on AUC, was decreased in patients with moderate and severe renal impairment by approximately 30% and 40%, respectively, as compared with subjects with normal renal function. Data are not available in renally impaired patients during long-term use of itraconazole. Dialysis has no effect on the half-life or clearance of itraconazole or hydroxy-itraconazole. (See PRECAUTIONS and DOSAGE AND ADMINISTRATION.). Hepatic Impairment. Itraconazole is predominantly metabolized in the liver. pharmacokinetic study was conducted in healthy and 12 cirrhotic subjects who were administered single 100-mg dose of itraconazole as capsule. statistically significant reduction in mean Cmax (47%) and twofold increase in the elimination half-life (37+-17 hours vs. 16+-5 hours) of itraconazole were noted in cirrhotic subjects compared with healthy subjects. However, overall exposure to itraconazole, based on AUC, was similar in cirrhotic patients and in healthy subjects. Data are not available in cirrhotic patients during long-term use of itraconazole. (See CONTRAINDICATIONS, PRECAUTIONS: Drug Interactions and DOSAGE AND ADMINISTRATION.). Decreased Cardiac Contractility. When itraconazole was administered intravenously to anesthetized dogs, dose-related negative inotropic effect was documented. In healthy volunteer study of itraconazole intravenous infusion, transient, asymptomatic decreases in left ventricular ejection fraction were observed using gated SPECT imaging; these resolved before the next infusion, 12 hours later. If signs or symptoms of congestive heart failure appear during administration of Itraconazole Capsules, itraconazole should be discontinued. (See BOXED WARNING, CONTRAINDICATIONS, WARNINGS, PRECAUTIONS: Drug Interactions and ADVERSE REACTIONS: Post-marketing Experience for more information.). MICROBIOLOGY. Mechanism of Action. In vitro studies have demonstrated that itraconazole inhibits the cytochrome P450-dependent synthesis of ergosterol, which is vital component of fungal cell membranes.. Antimicrobial Activity. Itraconazole exhibits in vitro activity against Blastomyces dermatitidis, Histoplasma capsulatum, Histoplasma duboisii, Aspergillus flavus, Aspergillus fumigatus, and Trichophyton species (See INDICATIONS AND USAGE: Description of Clinical Studies).. Susceptibility Testing Methods. For specific information regarding susceptibility test interpretive criteria and associated test methods and quality control standards recognized by FDA for this drug, please see: https://www.fda.gov/STIC.. Resistance. Isolates from several fungal species with decreased susceptibility to itraconazole have been isolated in vitro and from patients receiving prolonged therapy.Itraconazole is not active against Zygomycetes (e.g., Rhizopus spp., Rhizomucor spp., Mucor spp. and Absidia spp.), Fusarium spp., Scedosporium spp. and Scopulariopsis spp.. Cross-resistance. Several in vitro studies have reported that some fungal clinical isolates with reduced susceptibility to one azole antifungal agent may also be less susceptible to other azole derivatives. The finding of cross-resistance is dependent on number of factors, including the species evaluated, its clinical history, the particular azole compounds compared, and the type of susceptibility test that is performed.Studies (both in vitro and in vivo) suggest that the activity of amphotericin may be suppressed by prior azole antifungal therapy. As with other azoles, itraconazole inhibits the 14C-demethylation step in the synthesis of ergosterol, cell wall component of fungi. Ergosterol is the active site for amphotericin B. In one study the antifungal activity of amphotericin against Aspergillus fumigatus infections in mice was inhibited by ketoconazole therapy. The clinical significance of test results obtained in this study is unknown.

CLINICAL STUDIES SECTION.

Description of Clinical Studies. Blastomycosis. Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=73 combined) in patients with normal or abnormal immune status. The median dose was 200 mg/day. response for most signs and symptoms was observed within the first weeks, and all signs and symptoms cleared between and months. Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of blastomycosis compared with the natural history of untreated cases.. Histoplasmosis. Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=34 combined) in patients with normal or abnormal immune status (not including HIV-infected patients). The median dose was 200 mg/day. response for most signs and symptoms was observed within the first weeks, and all signs and symptoms cleared between and 12 months. Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of histoplasmosis, compared with the natural history of untreated cases.. Histoplasmosis in HIV-infected patients. Data from small number of HIV-infected patients suggested that the response rate of histoplasmosis in HIV-infected patients is similar to that of non-HIV-infected patients. The clinical course of histoplasmosis in HIV-infected patients is more severe and usually requires maintenance therapy to prevent relapse.. Aspergillosis. Analyses were conducted on data from an open-label, single-patient-use protocol designed to make itraconazole available in the U.S. for patients who either failed or were intolerant of amphotericin therapy (N=190). The findings were corroborated by two smaller open-label studies (N=31 combined) in the same patient population. Most adult patients were treated with daily dose of 200 to 400 mg, with median duration of months. Results of these studies demonstrated substantial evidence of effectiveness of itraconazole as second-line therapy for the treatment of aspergillosis compared with the natural history of the disease in patients who either failed or were intolerant of amphotericin therapy.. Onychomycosis of the toenail. Analyses were conducted on data from three double-blind, placebo-controlled studies (N=214 total; 110 given Itraconazole Capsules) in which patients with onychomycosis of the toenails received 200 mg of Itraconazole Capsules once daily for 12 consecutive weeks. Results of these studies demonstrated mycologic cure, defined as simultaneous occurrence of negative KOH plus negative culture, in 54% of patients. Thirty-five percent (35%) of patients were considered an overall success (mycologic cure plus clear or minimal nail involvement with significantly decreased signs) and 14% of patients demonstrated mycologic cure plus clinical cure (clearance of all signs, with or without residual nail deformity). The mean time to overall success was approximately 10 months. Twenty-one percent (21%) of the overall success group had relapse (worsening of the global score or conversion of KOH or culture from negative to positive).. Onychomycosis of the fingernail. Analyses were conducted on data from double-blind, placebo-controlled study (N=73 total; 37 given Itraconazole Capsules) in which patients with onychomycosis of the fingernails received 1-week course (pulse) of 200 mg of Itraconazole Capsules b.i.d., followed by 3-week period without Itraconazole Capsules, which was followed by second 1-week pulse of 200 mg of Itraconazole Capsules b.i.d. Results demonstrated mycologic cure in 61% of patients. Fifty-six percent (56%) of patients were considered an overall success and 47% of patients demonstrated mycologic cure plus clinical cure. The mean time to overall success was approximately months. None of the patients who achieved overall success relapsed.

CONTRAINDICATIONS SECTION.

CONTRAINDICATIONS. Congestive Heart Failure. Itraconazole Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or history of CHF. (See BOXED WARNING, WARNINGS, PRECAUTIONS: Drug Interactions-Calcium Channel Blockers, ADVERSE REACTIONS: Post-marketing Experience, and CLINICAL PHARMACOLOGY: Special Populations.). Drug Interactions. Coadministration of number of CYP3A4 substrates are contraindicated with itraconazole. Plasma concentrations increase for the following drugs: methadone, disopyramide, dofetilide, dronedarone, quinidine, isavuconazole, ergot alkaloids (such as dihydroergotamine, ergometrine (ergonovine), ergotamine, methylergometrine (methylergonovine)), irinotecan, lurasidone, oral midazolam, pimozide, triazolam, felodipine, nisoldipine, ivabradine, ranolazine, eplerenone, cisapride, naloxegol, lomitapide, lovastatin, simvastatin, avanafil, ticagrelor. In addition, coadministration with colchicine, fesoterodine and solifenacin is contraindicated in subjects with varying degrees of renal or hepatic impairment, and coadministration with eliglustat is contraindicated in subjects that are poor or intermediate metabolizers of CYP2D6 and in subjects taking strong or moderate CYP2D6 inhibitors. (See PRECAUTIONS: Drug Interactions Section for specific examples.) This increase in drug concentrations caused by coadministration with itraconazole may increase or prolong both the pharmacologic effects and/or adverse reactions to these drugs. For example, increased plasma concentrations of some of these drugs can lead to QT prolongation and ventricular tachyarrhythmias including occurrences of torsade de pointes, potentially fatal arrhythmia. Specific examples are listed in PRECAUTIONS: Drug Interactions.Itraconazole should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy.Itraconazole is contraindicated for patients who have shown hypersensitivity to itraconazole. There is limited information regarding cross-hypersensitivity between itraconazole and other azole antifungal agents. Caution should be used when prescribing itraconazole to patients with hypersensitivity to other azoles.

(See CLINICAL PHARMACOLOGY: Special Populations, WARNINGS, and PRECAUTIONS.).

DRUG INTERACTIONS SECTION.

Drug Interactions. Effect of Itraconazole Capsules on Other Drugs. Itraconazole and its major metabolite, hydroxy-itraconazole, are potent CYP3A4 inhibitors. Itraconazole is an inhibitor of the drug transporters P-glycoprotein and breast cancer resistance protein (BCRP). Consequently, Itraconazole Capsules has the potential to interact with many concomitant drugs resulting in either increased or sometimes decreased concentrations of the concomitant drugs. Increased concentrations may increase the risk of adverse reactions associated with the concomitant drug which can be severe or life-threatening in some cases (e.g., QT prolongation, Torsade de Pointes, respiratory depression, hepatic adverse reactions, hypersensitivity reactions, myelosuppression, hypotension, seizures, angioedema, atrial fibrillation, bradycardia, priapism). Reduced concentrations of concomitant drugs may reduce their efficacy. Table lists examples of drugs that may have their concentrations affected by itraconazole, but is not comprehensive list. Refer to the approved product labeling to become familiar with the interaction pathways, risk potential, and specific actions to be taken with regards to each concomitant drug prior to initiating therapy with Itraconazole Capsules.Although many of the clinical drug interactions in Table are based on information with similar azole antifungal, ketoconazole, these interactions are expected to occur with Itraconazole Capsules.Table Drug Interactions with Itraconazole Capsules that Affect Concomitant Drug ConcentrationsConcomitant Drug Within ClassPrevention or ManagementDrug Interactions with Itraconazole Capsules that Increase Concomitant Drug Concentrations and May Increase Risk of Adverse Reactions Associated with the Concomitant DrugAlpha BlockersAlfuzosinSilodosinTamsulosinNot recommended during and weeks after Itraconazole Capsules treatment.Analgesics MethadoneContraindicated during and weeks after Itraconazole Capsules treatment.FentanylNot recommended during and weeks after Itraconazole Capsules treatment.AlfentanilBuprenorphine (IV and sublingual)OxycodoneBased on clinical drug interaction information with itraconazole.

Effect of Other Drugs on Itraconazole Capsules. Itraconazole is mainly metabolized through CYP3A4. Other substances that either share this metabolic pathway or modify CYP3A4 activity may influence the pharmacokinetics of itraconazole. Some concomitant drugs have the potential to interact with Itraconazole Capsules resulting in either increased or sometimes decreased concentrations of Itraconazole Capsules. Increased concentrations may increase the risk of adverse reactions associated with Itraconazole Capsules. Decreased concentrations may reduce Itraconazole Capsules efficacy.Table lists examples of drugs that may affect itraconazole concentrations, but is not comprehensive list. Refer to the approved product labeling to become familiar with the interaction pathways, risk potential and specific actions to be taken with regards to each concomitant drug prior to initiating therapy with Itraconazole Capsules.Although many of the clinical drug interactions in Table are based on information with similar azole antifungal, ketoconazole, these interactions are expected to occur with Itraconazole Capsules.Table 2.

GENERAL PRECAUTIONS SECTION.

General. Itraconazole Capsules should be administered after full meal. (See CLINICAL PHARMACOLOGY: Pharmacokinetics and Metabolism).Under fasted conditions, itraconazole absorption was decreased in the presence of decreased gastric acidity. The absorption of itraconazole may be decreased with the concomitant administration of antacids or gastric acid secretion suppressors. Studies conducted under fasted conditions demonstrated that administration with ounces of non-diet cola beverage resulted in increased absorption of itraconazole in AIDS patients with relative or absolute achlorhydria. This increase relative to the effects of full meal is unknown. (See CLINICAL PHARMACOLOGY: Pharmacokinetics and Metabolism).

GERIATRIC USE SECTION.

Geriatric Use. Clinical studies of Itraconazole Capsules did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. It is advised to use Itraconazole Capsules in these patients only if it is determined that the potential benefit outweighs the potential risks. In general, it is recommended that the dose selection for an elderly patient should be taken into consideration, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.Transient or permanent hearing loss has been reported in elderly patients receiving treatment with itraconazole. Several of these reports included concurrent administration of quinidine which is contraindicated (See BOXED WARNING: Drug Interactions, CONTRAINDICATIONS: Drug Interactions and PRECAUTIONS: Drug Interactions).

HEPATIC IMPAIRMENT SUBSECTION.

Hepatic Impairment. Limited data are available on the use of oral itraconazole in patients with hepatic impairment. Caution should be exercised when this drug is administered in this patient population. It is recommended that patients with impaired hepatic function be carefully monitored when taking itraconazole. It is recommended that the prolonged elimination half-life of itraconazole observed in the single oral dose clinical trial with Itraconazole Capsules in cirrhotic patients be considered when deciding to initiate therapy with other medications metabolized by CYP3A4.In patients with elevated or abnormal liver enzymes or active liver disease, or who have experienced liver toxicity with other drugs, treatment with itraconazole is strongly discouraged unless there is serious or life-threatening situation where the expected benefit exceeds the risk. It is recommended that liver function monitoring be done in patients with pre-existing hepatic function abnormalities or those who have experienced liver toxicity with other medications. (See CLINICAL PHARMACOLOGY: Special Populations and DOSAGE AND ADMINISTRATION.).

HOW SUPPLIED SECTION.

HOW SUPPLIED. Itraconazole Capsules are available containing 100 mg of itraconazole, with blue opaque cap and pink transparent body, imprinted with PP 100. The capsules are supplied in bottles of 30 capsules (NDC 10147-1700-3) and in the DosingPak containing blister packs 4 capsules each (NDC 10147-1700-7).. Store at controlled room temperature 15-25C (59-77F). Protect from light and moisture.Keep out of reach of children.

INDICATIONS & USAGE SECTION.

INDICATIONS AND USAGE. Itraconazole Capsules are indicated for the treatment of the following fungal infections in immunocompromised and non-immunocompromised patients:Blastomycosis, pulmonary and extrapulmonaryHistoplasmosis, including chronic cavitary pulmonary disease and disseminated, non-meningeal histoplasmosis, andAspergillosis, pulmonary and extrapulmonary, in patients who are intolerant of or who are refractory to amphotericin therapy.Specimens for fungal cultures and other relevant laboratory studies (wet mount, histopathology, serology) should be obtained before therapy to isolate and identify causative organisms. Therapy may be instituted before the results of the cultures and other laboratory studies are known; however, once these results become available, antiinfective therapy should be adjusted accordingly.Itraconazole Capsules are also indicated for the treatment of the following fungal infections in non-immunocompromised patients:Onychomycosis of the toenail, with or without fingernail involvement, due to dermatophytes (tinea unguium), andOnychomycosis of the fingernail due to dermatophytes (tinea unguium).Prior to initiating treatment, appropriate nail specimens for laboratory testing (KOH preparation, fungal culture, or nail biopsy) should be obtained to confirm the diagnosis of onychomycosis.(See CLINICAL PHARMACOLOGY: Special Populations, CONTRAINDICATIONS, WARNINGS, and ADVERSE REACTIONS: Post-marketing Experience for more information.). Blastomycosis, pulmonary and extrapulmonary. Histoplasmosis, including chronic cavitary pulmonary disease and disseminated, non-meningeal histoplasmosis, and. Aspergillosis, pulmonary and extrapulmonary, in patients who are intolerant of or who are refractory to amphotericin therapy.. Onychomycosis of the toenail, with or without fingernail involvement, due to dermatophytes (tinea unguium), and. Onychomycosis of the fingernail due to dermatophytes (tinea unguium).. Description of Clinical Studies. Blastomycosis. Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=73 combined) in patients with normal or abnormal immune status. The median dose was 200 mg/day. response for most signs and symptoms was observed within the first weeks, and all signs and symptoms cleared between and months. Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of blastomycosis compared with the natural history of untreated cases.. Histoplasmosis. Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=34 combined) in patients with normal or abnormal immune status (not including HIV-infected patients). The median dose was 200 mg/day. response for most signs and symptoms was observed within the first weeks, and all signs and symptoms cleared between and 12 months. Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of histoplasmosis, compared with the natural history of untreated cases.. Histoplasmosis in HIV-infected patients. Data from small number of HIV-infected patients suggested that the response rate of histoplasmosis in HIV-infected patients is similar to that of non-HIV-infected patients. The clinical course of histoplasmosis in HIV-infected patients is more severe and usually requires maintenance therapy to prevent relapse.. Aspergillosis. Analyses were conducted on data from an open-label, single-patient-use protocol designed to make itraconazole available in the U.S. for patients who either failed or were intolerant of amphotericin therapy (N=190). The findings were corroborated by two smaller open-label studies (N=31 combined) in the same patient population. Most adult patients were treated with daily dose of 200 to 400 mg, with median duration of months. Results of these studies demonstrated substantial evidence of effectiveness of itraconazole as second-line therapy for the treatment of aspergillosis compared with the natural history of the disease in patients who either failed or were intolerant of amphotericin therapy.. Onychomycosis of the toenail. Analyses were conducted on data from three double-blind, placebo-controlled studies (N=214 total; 110 given Itraconazole Capsules) in which patients with onychomycosis of the toenails received 200 mg of Itraconazole Capsules once daily for 12 consecutive weeks. Results of these studies demonstrated mycologic cure, defined as simultaneous occurrence of negative KOH plus negative culture, in 54% of patients. Thirty-five percent (35%) of patients were considered an overall success (mycologic cure plus clear or minimal nail involvement with significantly decreased signs) and 14% of patients demonstrated mycologic cure plus clinical cure (clearance of all signs, with or without residual nail deformity). The mean time to overall success was approximately 10 months. Twenty-one percent (21%) of the overall success group had relapse (worsening of the global score or conversion of KOH or culture from negative to positive).. Onychomycosis of the fingernail. Analyses were conducted on data from double-blind, placebo-controlled study (N=73 total; 37 given Itraconazole Capsules) in which patients with onychomycosis of the fingernails received 1-week course (pulse) of 200 mg of Itraconazole Capsules b.i.d., followed by 3-week period without Itraconazole Capsules, which was followed by second 1-week pulse of 200 mg of Itraconazole Capsules b.i.d. Results demonstrated mycologic cure in 61% of patients. Fifty-six percent (56%) of patients were considered an overall success and 47% of patients demonstrated mycologic cure plus clinical cure. The mean time to overall success was approximately months. None of the patients who achieved overall success relapsed.

MECHANISM OF ACTION SECTION.

Mechanism of Action. In vitro studies have demonstrated that itraconazole inhibits the cytochrome P450-dependent synthesis of ergosterol, which is vital component of fungal cell membranes.

MICROBIOLOGY SECTION.

MICROBIOLOGY. Mechanism of Action. In vitro studies have demonstrated that itraconazole inhibits the cytochrome P450-dependent synthesis of ergosterol, which is vital component of fungal cell membranes.. Antimicrobial Activity. Itraconazole exhibits in vitro activity against Blastomyces dermatitidis, Histoplasma capsulatum, Histoplasma duboisii, Aspergillus flavus, Aspergillus fumigatus, and Trichophyton species (See INDICATIONS AND USAGE: Description of Clinical Studies).. Susceptibility Testing Methods. For specific information regarding susceptibility test interpretive criteria and associated test methods and quality control standards recognized by FDA for this drug, please see: https://www.fda.gov/STIC.. Resistance. Isolates from several fungal species with decreased susceptibility to itraconazole have been isolated in vitro and from patients receiving prolonged therapy.Itraconazole is not active against Zygomycetes (e.g., Rhizopus spp., Rhizomucor spp., Mucor spp. and Absidia spp.), Fusarium spp., Scedosporium spp. and Scopulariopsis spp.. Cross-resistance. Several in vitro studies have reported that some fungal clinical isolates with reduced susceptibility to one azole antifungal agent may also be less susceptible to other azole derivatives. The finding of cross-resistance is dependent on number of factors, including the species evaluated, its clinical history, the particular azole compounds compared, and the type of susceptibility test that is performed.Studies (both in vitro and in vivo) suggest that the activity of amphotericin may be suppressed by prior azole antifungal therapy. As with other azoles, itraconazole inhibits the 14C-demethylation step in the synthesis of ergosterol, cell wall component of fungi. Ergosterol is the active site for amphotericin B. In one study the antifungal activity of amphotericin against Aspergillus fumigatus infections in mice was inhibited by ketoconazole therapy. The clinical significance of test results obtained in this study is unknown.

NURSING MOTHERS SECTION.

Nursing Mothers. Itraconazole is excreted in human milk; therefore, the expected benefits of itraconazole therapy for the mother should be weighed against the potential risk from exposure of itraconazole to the infant. The U.S. Public Health Service Centers for Disease Control and Prevention advises HIV-infected women not to breast-feed to avoid potential transmission of HIV to uninfected infants.

OVERDOSAGE SECTION.

OVERDOSAGE. Itraconazole is not removed by dialysis. In the event of accidental overdosage, supportive measures should be employed. Contact certified poison control center for the most up to date information on the management of Itraconazole Capsules overdosage (1-800-222-1222 or www.poison.org).In general, adverse events reported with overdose have been consistent with adverse drug reactions already listed in this package insert for itraconazole. (See ADVERSE REACTIONS.).

PEDIATRIC USE SECTION.

Pediatric Use. The efficacy and safety of itraconazole have not been established in pediatric patients.The long-term effects of itraconazole on bone growth in children are unknown. In three toxicology studies using rats, itraconazole induced bone defects at dosage levels as low as 20 mg/kg/day (2.5 times the MRHD). The induced defects included reduced bone plate activity, thinning of the zona compacta of the large bones, and increased bone fragility. At dosage level of 80 mg/kg/day (10 times the MRHD) over year or 160 mg/kg/day (20 times the MRHD) for months, itraconazole induced small tooth pulp with hypocellular appearance in some rats.

PHARMACOKINETICS SECTION.

Pharmacokinetics and Metabolism. General Pharmacokinetic Characteristics. Peak plasma concentrations of itraconazole are reached within to hours following oral administration. As consequence of non-linear pharmacokinetics, itraconazole accumulates in plasma during multiple dosing. Steady-state concentrations are generally reached within about 15 days, with Cmax values of 0.5 ug/mL, 1.1 ug/mL and 2.0 ug/mL after oral administration of 100 mg once daily, 200 mg once daily and 200 mg b.i.d., respectively. The terminal half-life of itraconazole generally ranges from 16 to 28 hours after single dose and increases to 34 to 42 hours with repeated dosing. Once treatment is stopped, itraconazole plasma concentrations decrease to an almost undetectable concentration within to 14 days, depending on the dose and duration of treatment. Itraconazole mean total plasma clearance following intravenous administration is 278 mL/min. Itraconazole clearance decreases at higher doses due to saturable hepatic metabolism.. Absorption. Itraconazole is rapidly absorbed after oral administration. Peak plasma concentrations of itraconazole are reached within to hours following an oral capsule dose. The observed absolute oral bioavailability of itraconazole is about 55%.The oral bioavailability of itraconazole is maximal when Itraconazole Capsules are taken immediately after full meal.Absorption of itraconazole capsules is reduced in subjects with reduced gastric acidity, such as subjects taking medications known as gastric acid secretion suppressors (e.g., H2-receptor antagonists, proton pump inhibitors) or subjects with achlorhydria caused by certain diseases. (See PRECAUTIONS: Drug Interactions.) Absorption of itraconazole under fasted conditions in these subjects is increased when Itraconazole Capsules are administered with an acidic beverage (such as non-diet cola). When Itraconazole Capsules were administered as single 200-mg dose under fasted conditions with non-diet cola after ranitidine pretreatment, H2-receptor antagonist, itraconazole absorption was comparable to that observed when Itraconazole Capsules were administered alone. (See PRECAUTIONS: Drug Interactions.)Itraconazole exposure is lower with the Capsule formulation than with the Oral Solution when the same dose of drug is given. (See WARNINGS). Distribution. Most of the itraconazole in plasma is bound to protein (99.8%), with albumin being the main binding component (99.6% for the hydroxy-metabolite). It has also marked affinity for lipids. Only 0.2% of the itraconazole in plasma is present as free drug. Itraconazole is distributed in large apparent volume in the body (>700 L), suggesting extensive distribution into tissues. Concentrations in lung, kidney, liver, bone, stomach, spleen and muscle were found to be two to three times higher than corresponding concentrations in plasma, and the uptake into keratinous tissues, skin in particular, up to four times higher. Concentrations in the cerebrospinal fluid are much lower than in plasma.. Metabolism. Itraconazole is extensively metabolized by the liver into large number of metabolites. In vitro studies have shown that CYP3A4 is the major enzyme involved in the metabolism of itraconazole. The main metabolite is hydroxy-itraconazole, which has in vitro antifungal activity comparable to itraconazole; trough plasma concentrations of this metabolite are about twice those of itraconazole.. Excretion. Itraconazole is excreted mainly as inactive metabolites in urine (35%) and in feces (54%) within one week of an oral solution dose. Renal excretion of itraconazole and the active metabolite hydroxy-itraconazole account for less than 1% of an intravenous dose. Based on an oral radiolabeled dose, fecal excretion of unchanged drug ranges from 3% to 18% of the dose.As re-distribution of itraconazole from keratinous tissues appears to be negligible, elimination of itraconazole from these tissues is related to epidermal regeneration. Contrary to plasma, the concentration in skin persists for to weeks after discontinuation of 4-week treatment and in nail keratin where itraconazole can be detected as early as week after start of treatment for at least six months after the end of 3-month treatment period.. Special Populations. Renal Impairment. Limited data are available on the use of oral itraconazole in patients with renal impairment. pharmacokinetic study using single 200-mg oral dose of itraconazole was conducted in three groups of patients with renal impairment (uremia: n=7; hemodialysis: n=7; and continuous ambulatory peritoneal dialysis: n=5). In uremic subjects with mean creatinine clearance of 13 mL/min. 1.73 m2, the exposure, based on AUC, was slightly reduced compared with normal population parameters. This study did not demonstrate any significant effect of hemodialysis or continuous ambulatory peritoneal dialysis on the pharmacokinetics of itraconazole (Tmax, Cmax, and AUC0-8h). Plasma concentration-versus-time profiles showed wide intersubject variation in all three groups. After single intravenous dose, the mean terminal half-lives of itraconazole in patients with mild (defined in this study as CrCl 50-79 mL/min), moderate (defined in this study as CrCl 20-49 mL/min), and severe renal impairment (defined in this study as CrCl <20 mL/min) were similar to that in healthy subjects (range of means 42-49 hours vs 48 hours in renally impaired patients and healthy subjects, respectively). Overall exposure to itraconazole, based on AUC, was decreased in patients with moderate and severe renal impairment by approximately 30% and 40%, respectively, as compared with subjects with normal renal function. Data are not available in renally impaired patients during long-term use of itraconazole. Dialysis has no effect on the half-life or clearance of itraconazole or hydroxy-itraconazole. (See PRECAUTIONS and DOSAGE AND ADMINISTRATION.). Hepatic Impairment. Itraconazole is predominantly metabolized in the liver. pharmacokinetic study was conducted in healthy and 12 cirrhotic subjects who were administered single 100-mg dose of itraconazole as capsule. statistically significant reduction in mean Cmax (47%) and twofold increase in the elimination half-life (37+-17 hours vs. 16+-5 hours) of itraconazole were noted in cirrhotic subjects compared with healthy subjects. However, overall exposure to itraconazole, based on AUC, was similar in cirrhotic patients and in healthy subjects. Data are not available in cirrhotic patients during long-term use of itraconazole. (See CONTRAINDICATIONS, PRECAUTIONS: Drug Interactions and DOSAGE AND ADMINISTRATION.). Decreased Cardiac Contractility. When itraconazole was administered intravenously to anesthetized dogs, dose-related negative inotropic effect was documented. In healthy volunteer study of itraconazole intravenous infusion, transient, asymptomatic decreases in left ventricular ejection fraction were observed using gated SPECT imaging; these resolved before the next infusion, 12 hours later. If signs or symptoms of congestive heart failure appear during administration of Itraconazole Capsules, itraconazole should be discontinued. (See BOXED WARNING, CONTRAINDICATIONS, WARNINGS, PRECAUTIONS: Drug Interactions and ADVERSE REACTIONS: Post-marketing Experience for more information.).

PRECAUTIONS SECTION.

PRECAUTIONS. General. Itraconazole Capsules should be administered after full meal. (See CLINICAL PHARMACOLOGY: Pharmacokinetics and Metabolism).Under fasted conditions, itraconazole absorption was decreased in the presence of decreased gastric acidity. The absorption of itraconazole may be decreased with the concomitant administration of antacids or gastric acid secretion suppressors. Studies conducted under fasted conditions demonstrated that administration with ounces of non-diet cola beverage resulted in increased absorption of itraconazole in AIDS patients with relative or absolute achlorhydria. This increase relative to the effects of full meal is unknown. (See CLINICAL PHARMACOLOGY: Pharmacokinetics and Metabolism).. Hepatotoxicity. Rare cases of serious hepatotoxicity have been observed with itraconazole treatment, including some cases within the first week. It is recommended that liver function monitoring be considered in all patients receiving itraconazole. Treatment should be stopped immediately and liver function testing should be conducted in patients who develop signs and symptoms suggestive of liver dysfunction.. Neuropathy. If neuropathy occurs that may be attributable to Itraconazole Capsules, the treatment should be discontinued.. Immunocompromised Patients. In some immunocompromised patients (e.g., neutropenic, AIDS or organ transplant patients), the oral bioavailability of Itraconazole capsules may be decreased. Therefore, the dose should be adjusted based on the clinical response in these patients.. Cystic Fibrosis. If cystic fibrosis patient does not respond to Itraconazole Capsules, consideration should be given to switching to alternative therapy. For more information concerning the use of itraconazole in cystic fibrosis patients see the prescribing information for SPORANOX(R) Oral Solution.. Hearing Loss. Transient or permanent hearing loss has been reported in patients receiving treatment with itraconazole. Several of these reports included concurrent administration of quinidine which is contraindicated (See BOXED WARNING: Drug Interactions, CONTRAINDICATIONS: Drug Interactions and PRECAUTIONS: Drug Interactions). The hearing loss usually resolves when treatment is stopped, but can persist in some patients.. Information for Patients. The topical effects of mucosal exposure may be different between Itraconazole Capsules and SPORANOX(R) (itraconazole) Oral Solution.

Drug Interactions. Effect of Itraconazole Capsules on Other Drugs. Itraconazole and its major metabolite, hydroxy-itraconazole, are potent CYP3A4 inhibitors. Itraconazole is an inhibitor of the drug transporters P-glycoprotein and breast cancer resistance protein (BCRP). Consequently, Itraconazole Capsules has the potential to interact with many concomitant drugs resulting in either increased or sometimes decreased concentrations of the concomitant drugs. Increased concentrations may increase the risk of adverse reactions associated with the concomitant drug which can be severe or life-threatening in some cases (e.g., QT prolongation, Torsade de Pointes, respiratory depression, hepatic adverse reactions, hypersensitivity reactions, myelosuppression, hypotension, seizures, angioedema, atrial fibrillation, bradycardia, priapism). Reduced concentrations of concomitant drugs may reduce their efficacy. Table lists examples of drugs that may have their concentrations affected by itraconazole, but is not comprehensive list. Refer to the approved product labeling to become familiar with the interaction pathways, risk potential, and specific actions to be taken with regards to each concomitant drug prior to initiating therapy with Itraconazole Capsules.Although many of the clinical drug interactions in Table are based on information with similar azole antifungal, ketoconazole, these interactions are expected to occur with Itraconazole Capsules.Table Drug Interactions with Itraconazole Capsules that Affect Concomitant Drug ConcentrationsConcomitant Drug Within ClassPrevention or ManagementDrug Interactions with Itraconazole Capsules that Increase Concomitant Drug Concentrations and May Increase Risk of Adverse Reactions Associated with the Concomitant DrugAlpha BlockersAlfuzosinSilodosinTamsulosinNot recommended during and weeks after Itraconazole Capsules treatment.Analgesics MethadoneContraindicated during and weeks after Itraconazole Capsules treatment.FentanylNot recommended during and weeks after Itraconazole Capsules treatment.AlfentanilBuprenorphine (IV and sublingual)OxycodoneBased on clinical drug interaction information with itraconazole.

Effect of Other Drugs on Itraconazole Capsules. Itraconazole is mainly metabolized through CYP3A4. Other substances that either share this metabolic pathway or modify CYP3A4 activity may influence the pharmacokinetics of itraconazole. Some concomitant drugs have the potential to interact with Itraconazole Capsules resulting in either increased or sometimes decreased concentrations of Itraconazole Capsules. Increased concentrations may increase the risk of adverse reactions associated with Itraconazole Capsules. Decreased concentrations may reduce Itraconazole Capsules efficacy.Table lists examples of drugs that may affect itraconazole concentrations, but is not comprehensive list. Refer to the approved product labeling to become familiar with the interaction pathways, risk potential and specific actions to be taken with regards to each concomitant drug prior to initiating therapy with Itraconazole Capsules.Although many of the clinical drug interactions in Table are based on information with similar azole antifungal, ketoconazole, these interactions are expected to occur with Itraconazole Capsules.Table 2.

Pediatric Population. Interaction studies have only been performed in adults.. Carcinogenesis, Mutagenesis, and Impairment of Fertility. Itraconazole showed no evidence of carcinogenicity potential in mice treated orally for 23 months at dosage levels up to 80 mg/kg/day (approximately 10 times the maximum recommended human dose [MRHD]). Male rats treated with 25 mg/kg/day (3.1 times the MRHD) had slightly increased incidence of soft tissue sarcoma. These sarcomas may have been consequence of hypercholesterolemia, which is response of rats, but not dogs or humans, to chronic itraconazole administration. Female rats treated with 50 mg/kg/day (6.25 times the MRHD) had an increased incidence of squamous cell carcinoma of the lung (2/50) as compared to the untreated group. Although the occurrence of squamous cell carcinoma in the lung is extremely uncommon in untreated rats, the increase in this study was not statistically significant.Itraconazole produced no mutagenic effects when assayed in DNA repair test (unscheduled DNA synthesis) in primary rat hepatocytes, in Ames tests with Salmonella typhimurium (6 strains) and Escherichia coli, in the mouse lymphoma gene mutation tests, in sex-linked recessive lethal mutation (Drosophila melanogaster) test, in chromosome aberration tests in human lymphocytes, in cell transformation test with C3H/10T 1/2 C18 mouse embryo fibroblasts cells, in dominant lethal mutation test in male and female mice, and in micronucleus tests in mice and rats.Itraconazole did not affect the fertility of male or female rats treated orally with dosage levels of up to 40 mg/kg/day (5 times the MRHD), even though parental toxicity was present at this dosage level. More severe signs of parental toxicity, including death, were present in the next higher dosage level, 160 mg/kg/day (20 times the MRHD).. Pregnancy. Teratogenic effects. Itraconazole was found to cause dose-related increase in maternal toxicity, embryotoxicity, and teratogenicity in rats at dosage levels of approximately 40-160 mg/kg/day (5-20 times the MRHD), and in mice at dosage levels of approximately 80 mg/kg/day (10 times the MRHD). Itraconazole has been shown to cross the placenta in rat model. In rats, the teratogenicity consisted of major skeletal defects; in mice, it consisted of encephaloceles and/or macroglossia.There are no studies in pregnant women. Itraconazole should be used for the treatment of systemic fungal infections in pregnancy only if the benefit outweighs the potential risk.Itraconazole should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy. Itraconazole should not be administered to women of childbearing potential for the treatment of onychomycosis unless they are using effective measures to prevent pregnancy and they begin therapy on the second or third day following the onset of menses. Highly effective contraception should be continued throughout itraconazole therapy and for months following the end of treatment.During post-marketing experience, cases of congenital abnormalities have been reported. (See ADVERSE REACTIONS: Post-marketing Experience.). Nursing Mothers. Itraconazole is excreted in human milk; therefore, the expected benefits of itraconazole therapy for the mother should be weighed against the potential risk from exposure of itraconazole to the infant. The U.S. Public Health Service Centers for Disease Control and Prevention advises HIV-infected women not to breast-feed to avoid potential transmission of HIV to uninfected infants.. Pediatric Use. The efficacy and safety of itraconazole have not been established in pediatric patients.The long-term effects of itraconazole on bone growth in children are unknown. In three toxicology studies using rats, itraconazole induced bone defects at dosage levels as low as 20 mg/kg/day (2.5 times the MRHD). The induced defects included reduced bone plate activity, thinning of the zona compacta of the large bones, and increased bone fragility. At dosage level of 80 mg/kg/day (10 times the MRHD) over year or 160 mg/kg/day (20 times the MRHD) for months, itraconazole induced small tooth pulp with hypocellular appearance in some rats.. Geriatric Use. Clinical studies of Itraconazole Capsules did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. It is advised to use Itraconazole Capsules in these patients only if it is determined that the potential benefit outweighs the potential risks. In general, it is recommended that the dose selection for an elderly patient should be taken into consideration, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.Transient or permanent hearing loss has been reported in elderly patients receiving treatment with itraconazole. Several of these reports included concurrent administration of quinidine which is contraindicated (See BOXED WARNING: Drug Interactions, CONTRAINDICATIONS: Drug Interactions and PRECAUTIONS: Drug Interactions).. HIV-Infected Patients. Because hypochlorhydria has been reported in HIV-infected individuals, the absorption of itraconazole in these patients may be decreased.. Renal Impairment. Limited data are available on the use of oral itraconazole in patients with renal impairment. The exposure of itraconazole may be lower in some patients with renal impairment. Caution should be exercised when itraconazole is administered in this patient population and dose adjustment may be needed. (See CLINICAL PHARMACOLOGY: Special Populations and DOSAGE AND ADMINISTRATION.). Hepatic Impairment. Limited data are available on the use of oral itraconazole in patients with hepatic impairment. Caution should be exercised when this drug is administered in this patient population. It is recommended that patients with impaired hepatic function be carefully monitored when taking itraconazole. It is recommended that the prolonged elimination half-life of itraconazole observed in the single oral dose clinical trial with Itraconazole Capsules in cirrhotic patients be considered when deciding to initiate therapy with other medications metabolized by CYP3A4.In patients with elevated or abnormal liver enzymes or active liver disease, or who have experienced liver toxicity with other drugs, treatment with itraconazole is strongly discouraged unless there is serious or life-threatening situation where the expected benefit exceeds the risk. It is recommended that liver function monitoring be done in patients with pre-existing hepatic function abnormalities or those who have experienced liver toxicity with other medications. (See CLINICAL PHARMACOLOGY: Special Populations and DOSAGE AND ADMINISTRATION.).

PREGNANCY SECTION.

Pregnancy. Teratogenic effects. Itraconazole was found to cause dose-related increase in maternal toxicity, embryotoxicity, and teratogenicity in rats at dosage levels of approximately 40-160 mg/kg/day (5-20 times the MRHD), and in mice at dosage levels of approximately 80 mg/kg/day (10 times the MRHD). Itraconazole has been shown to cross the placenta in rat model. In rats, the teratogenicity consisted of major skeletal defects; in mice, it consisted of encephaloceles and/or macroglossia.There are no studies in pregnant women. Itraconazole should be used for the treatment of systemic fungal infections in pregnancy only if the benefit outweighs the potential risk.Itraconazole should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy. Itraconazole should not be administered to women of childbearing potential for the treatment of onychomycosis unless they are using effective measures to prevent pregnancy and they begin therapy on the second or third day following the onset of menses. Highly effective contraception should be continued throughout itraconazole therapy and for months following the end of treatment.During post-marketing experience, cases of congenital abnormalities have been reported. (See ADVERSE REACTIONS: Post-marketing Experience.).

RENAL IMPAIRMENT SUBSECTION.

Renal Impairment. Limited data are available on the use of oral itraconazole in patients with renal impairment. The exposure of itraconazole may be lower in some patients with renal impairment. Caution should be exercised when itraconazole is administered in this patient population and dose adjustment may be needed.

TERATOGENIC EFFECTS SECTION.

Teratogenic effects. Itraconazole was found to cause dose-related increase in maternal toxicity, embryotoxicity, and teratogenicity in rats at dosage levels of approximately 40-160 mg/kg/day (5-20 times the MRHD), and in mice at dosage levels of approximately 80 mg/kg/day (10 times the MRHD). Itraconazole has been shown to cross the placenta in rat model. In rats, the teratogenicity consisted of major skeletal defects; in mice, it consisted of encephaloceles and/or macroglossia.There are no studies in pregnant women. Itraconazole should be used for the treatment of systemic fungal infections in pregnancy only if the benefit outweighs the potential risk.Itraconazole should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy. Itraconazole should not be administered to women of childbearing potential for the treatment of onychomycosis unless they are using effective measures to prevent pregnancy and they begin therapy on the second or third day following the onset of menses. Highly effective contraception should be continued throughout itraconazole therapy and for months following the end of treatment.During post-marketing experience, cases of congenital abnormalities have been reported. (See ADVERSE REACTIONS: Post-marketing Experience.).

WARNINGS SECTION.

WARNINGS. Hepatic Effects. Itraconazole has been associated with rare cases of serious hepatotoxicity, including liver failure and death. Some of these cases had neither pre-existing liver disease nor serious underlying medical condition, and some of these cases developed within the first week of treatment. If clinical signs or symptoms develop that are consistent with liver disease, treatment should be discontinued and liver function testing performed. Continued itraconazole use or reinstitution of treatment with itraconazole is strongly discouraged unless there is serious or life-threatening situation where the expected benefit exceeds the risk. (See PRECAUTIONS: Information for Patients and ADVERSE REACTIONS.). Cardiac Dysrhythmias. Life-threatening cardiac dysrhythmias and/or sudden death have occurred in patients using drugs such as cisapride, pimozide, methadone, or quinidine concomitantly with itraconazole and/or other CYP3A4 inhibitors. Concomitant administration of these drugs with itraconazole is contraindicated. (See BOXED WARNING, CONTRAINDICATIONS, and PRECAUTIONS: Drug Interactions.). Cardiac Disease. Itraconazole Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or history of CHF. Itraconazole Capsules should not be used for other indications in patients with evidence of ventricular dysfunction unless the benefit clearly outweighs the risk.For patients with risk factors for congestive heart failure, physicians should carefully review the risks and benefits of itraconazole therapy. These risk factors include cardiac disease such as ischemic and valvular disease; significant pulmonary disease such as chronic obstructive pulmonary disease; and renal failure and other edematous disorders. Such patients should be informed of the signs and symptoms of CHF, should be treated with caution, and should be monitored for signs and symptoms of CHF during treatment. If signs or symptoms of CHF appear during administration of Itraconazole Capsules, discontinue administration.Itraconazole has been shown to have negative inotropic effect. When itraconazole was administered intravenously to anesthetized dogs, dose-related negative inotropic effect was documented. In healthy volunteer study of itraconazole intravenous infusion, transient, asymptomatic decreases in left ventricular ejection fraction were observed using gated SPECT imaging; these resolved before the next infusion, 12 hours later.Itraconazole has been associated with reports of congestive heart failure. In post-marketing experience, heart failure was more frequently reported in patients receiving total daily dose of 400 mg although there were also cases reported among those receiving lower total daily doses.Calcium channel blockers can have negative inotropic effects which may be additive to those of itraconazole. In addition, itraconazole can inhibit the metabolism of calcium channel blockers. Therefore, caution should be used when co-administering itraconazole and calcium channel blockers due to an increased risk of CHF. Concomitant administration of itraconazole and felodipine or nisoldipine is contraindicated.Cases of CHF, peripheral edema, and pulmonary edema have been reported in the post-marketing period among patients being treated for onychomycosis and/or systemic fungal infections. (See CLINICAL PHARMACOLOGY: Special Populations, CONTRAINDICATIONS, PRECAUTIONS: Drug Interactions, and ADVERSE REACTIONS: Post-marketing Experience for more information.). Interaction potential. Itraconazole has potential for clinically important drug interactions. Coadministration of specific drugs with itraconazole may result in changes in efficacy of itraconazole and/or the coadministered drug, life-threatening effects and/or sudden death. Drugs that are contraindicated, not recommended or recommended for use with caution in combination with itraconazole are listed in PRECAUTIONS: Drug Interactions.. Interchangeability. Itraconazole Capsules and SPORANOX(R) (itraconazole) Oral Solution should not be used interchangeably. This is because drug exposure is greater with the Oral Solution than with the Capsules when the same dose of drug is given. In addition, the topical effects of mucosal exposure may be different between the two formulations. Only the Oral Solution has been demonstrated effective for oral and/or esophageal candidiasis.
