CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenesis--Long-term animal studies have not been performed to evaluate the carcinogenic potential of minocycline. structurally related compound, oxytetracycline, was found to produce adrenal and pituitary tumors in rats.. Mutagenesis--Minocycline was not mutagenic in vitro in bacterial reverse mutation assay (Ames test) or CHO/HGPRT mammalian cell assay in the presence or absence of metabolic activation. Minocycline was not clastogenic in vitro using human peripheral blood lymphocytes or in vivo in mouse micronucleus test.. Impairment of Fertility--Male and female reproductive performance in rats was unaffected by oral doses of minocycline of up to 300 mg/kg/day (which resulted in up to approximately 40 times the level of systemic exposure to minocycline observed in patients as result of use of SOLODYN). However, oral administration of 100 or 300 mg/kg/day of minocycline to male rats (resulting in approximately 15 to 40 times the level of systemic exposure to minocycline observed in patients as result of use of SOLODYN) adversely affected spermatogenesis. Effects observed at 300 mg/kg/day included reduced number of sperm cells per gram of epididymis, an apparent reduction in the percentage of sperm that were motile, and (at 100 and 300 mg/kg/day) increased numbers of morphologically abnormal sperm cells. Morphological abnormalities observed in sperm samples included absent heads, misshapen heads, and abnormal flagella.Limited human studies suggest that minocycline may have deleterious effect on spermatogenesis.SOLODYN should not be used by individuals of either gender who are attempting to conceive child.

CLINICAL PHARMACOLOGY SECTION.

12CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. The mechanism of action of SOLODYN for the treatment of acne is unknown.. 12.2 Pharmacodynamics. The pharmacodynamics of SOLODYN for the treatment of acne are unknown.. 12.3Pharmacokinetics. SOLODYN Tablets are not bioequivalent to non-modified release minocycline products. Based on pharmacokinetic studies in healthy adults, SOLODYN Tablets produce delayed Tmax at 3.5-4.0 hours as compared to non-modified release reference minocycline product (Tmax at 2.25-3 hours). At steady-state (Day 6), the mean AUC(0-24) and Cmax were 33.32 ugxhr/mL and 2.63 ug/mL for SOLODYN Tablets and 46.35 ugxhr/mL and 2.92 ug/mL for Minocin(R) capsules, respectively. These parameters are based on dose adjusted to 135 mg per day for both products.A single-dose, four-way crossover study demonstrated that SOLODYN Tablets used in the study (45 mg, 90 mg, 135 mg) exhibited dose-proportional pharmacokinetics. In another single-dose, five-way crossover pharmacokinetic study, SOLODYN Tablets 55 mg, 80 mg, and 105 mg were shown to be dose-proportional to SOLODYN Tablets 90 mg and 135 mg.When SOLODYN Tablets were administered concomitantly with meal that included dairy products, the extent and timing of absorption of minocycline did not differ from that of administration under fasting conditions.Minocycline is lipid soluble and distributes into the skin and sebum.

DRUG & OR LABORATORY TEST INTERACTIONS SECTION.

7.6Drug/Laboratory Test Interactions. False elevations of urinary catecholamine levels may occur due to interference with the fluorescence test.

DRUG INTERACTIONS SECTION.

7DRUG INTERACTIONS. Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. (7.1) The concurrent use of tetracycline and methoxyflurane has been reported to result in fatal renal toxicity. (7.3) To avoid contraceptive failure, female patients are advised to use second form of contraceptive during treatment with minocycline. (7.5). Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. (7.1). The concurrent use of tetracycline and methoxyflurane has been reported to result in fatal renal toxicity. (7.3). To avoid contraceptive failure, female patients are advised to use second form of contraceptive during treatment with minocycline. (7.5). 7.1Anticoagulants. Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. 7.2 Penicillin. Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracycline-class drugs in conjunction with penicillin. 7.3Methoxyflurane. The concurrent use of tetracycline and methoxyflurane has been reported to result in fatal renal toxicity.. 7.4Antacids and Iron Preparations. Absorption of tetracyclines is impaired by antacids containing aluminum, calcium or magnesium and iron-containing preparations.. 7.5Low Dose Oral Contraceptives. In multi-center study to evaluate the effect of SOLODYN on low dose oral contraceptives, hormone levels over one menstrual cycle with and without SOLODYN mg/kg once-daily were measured. Based on the results of this trial, minocycline-related changes in estradiol, progestinic hormone, FSH and LH plasma levels, of breakthrough bleeding, or of contraceptive failure, can not be ruled out. To avoid contraceptive failure, female patients are advised to use second form of contraceptive during treatment with minocycline.. 7.6Drug/Laboratory Test Interactions. False elevations of urinary catecholamine levels may occur due to interference with the fluorescence test.

GERIATRIC USE SECTION.

8.5Geriatric Use. Clinical studies of SOLODYN did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease or other drug therapy.

INFORMATION FOR PATIENTS SECTION.

17PATIENT COUNSELING INFORMATION. [See FDA-approved patient labeling (Patient Information)]Patients taking SOLODYN (minocycline HCl, USP) Extended Release Tablets should receive the following information and instructions: SOLODYN should not be used by pregnant women or women attempting to conceive child [see Use in Specific Populations (8.1), Nonclinical Toxicology (13.1)]. It is recommended that SOLODYN not be used by men who are attempting to father child [see Nonclinical Toxicology (13.1)]. Patients should be advised that pseudomembranous colitis can occur with minocycline therapy. If patients develop watery or bloody stools, they should seek medical attention. Patients should be counseled about the possibility of hepatotoxicity. Patients should seek medical advice if they experience symptoms which can include loss of appetite, tiredness, diarrhea, skin turning yellow, bleeding easily, confusion, and sleepiness. Patients who experience central nervous system symptoms [see Warnings and Precautions (5.5)] should be cautioned about driving vehicles or using hazardous machinery while on minocycline therapy. Patients should seek medical help for persistent headaches or blurred vision. Concurrent use of tetracycline may render oral contraceptives less effective [see Drug Interactions (7.5)]. Autoimmune syndromes, including drug-induced lupus-like syndrome, autoimmune hepatitis, vasculitis and serum sickness have been observed with tetracycline-class drugs, including minocycline. Symptoms may be manifested by arthralgia, fever, rash and malaise. Patients who experience such symptoms should be cautioned to stop the drug immediately and seek medical help. Patients should be counseled about discoloration of skin, scars, teeth or gums that can arise from minocycline therapy. Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines, including minocycline. Patients should minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using minocycline. If patients need to be outdoors while using minocycline, they should wear loose-fitting clothes that protect skin from sun exposure and discuss other sun protection measures with their physician. Treatment should be discontinued at the first evidence of skin erythema. SOLODYN should be taken exactly as directed. Skipping doses or not completing the full course of therapy may decrease the effectiveness of the current treatment course and increase the likelihood that bacteria will develop resistance and will not be treatable by other antibacterial drugs in the future. Patients should be advised to swallow SOLODYN Tablets whole and not to chew, crush, or split the tablets.. SOLODYN should not be used by pregnant women or women attempting to conceive child [see Use in Specific Populations (8.1), Nonclinical Toxicology (13.1)].

12.3Pharmacokinetics. SOLODYN Tablets are not bioequivalent to non-modified release minocycline products. Based on pharmacokinetic studies in healthy adults, SOLODYN Tablets produce delayed Tmax at 3.5-4.0 hours as compared to non-modified release reference minocycline product (Tmax at 2.25-3 hours). At steady-state (Day 6), the mean AUC(0-24) and Cmax were 33.32 ugxhr/mL and 2.63 ug/mL for SOLODYN Tablets and 46.35 ugxhr/mL and 2.92 ug/mL for Minocin(R) capsules, respectively. These parameters are based on dose adjusted to 135 mg per day for both products.A single-dose, four-way crossover study demonstrated that SOLODYN Tablets used in the study (45 mg, 90 mg, 135 mg) exhibited dose-proportional pharmacokinetics. In another single-dose, five-way crossover pharmacokinetic study, SOLODYN Tablets 55 mg, 80 mg, and 105 mg were shown to be dose-proportional to SOLODYN Tablets 90 mg and 135 mg.When SOLODYN Tablets were administered concomitantly with meal that included dairy products, the extent and timing of absorption of minocycline did not differ from that of administration under fasting conditions.Minocycline is lipid soluble and distributes into the skin and sebum.

PREGNANCY SECTION.

8.1Pregnancy. Teratogenic Effects: Pregnancy category [see Warnings and Precautions (5.1)]SOLODYN should not be used during pregnancy. If the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus and stop treatment immediately.There are no adequate and well-controlled studies on the use of minocycline in pregnant women. Minocycline, like other tetracycline-class drugs, crosses the placenta and may cause fetal harm when administered to pregnant woman.Rare spontaneous reports of congenital anomalies including limb reduction have been reported with minocycline use in pregnancy in post-marketing experience. Only limited information is available regarding these reports; therefore, no conclusion on causal association can be established.Minocycline induced skeletal malformations (bent limb bones) in fetuses when administered to pregnant rats and rabbits in doses of 30 mg/kg/day and 100 mg/kg/day, respectively, (resulting in approximately times and times, respectively, the systemic exposure to minocycline observed in patients as result of use of SOLODYN). Reduced mean fetal body weight was observed in studies in which minocycline was administered to pregnant rats at dose of 10 mg/kg/day (which resulted in approximately the same level of systemic exposure to minocycline as that observed in patients who use SOLODYN).Minocycline was assessed for effects on peri- and post-natal development of rats in study that involved oral administration to pregnant rats from day of gestation through the period of lactation (postpartum day 20), at dosages of 5, 10, or 50 mg/kg/day. In this study, body weight gain was significantly reduced in pregnant females that received 50 mg/kg/day (resulting in approximately 2.5 times the systemic exposure to minocycline observed in patients as result of use of SOLODYN). No effects of treatment on the duration of the gestation period or the number of live pups born per litter were observed. Gross external anomalies observed in F1 pups (offspring of animals that received minocycline) included reduced body size, improperly rotated forelimbs, and reduced size of extremities. No effects were observed on the physical development, behavior, learning ability, or reproduction of F1 pups, and there was no effect on gross appearance of F2 pups (offspring of F1 animals).

TERATOGENIC EFFECTS SECTION.

5.1Teratogenic Effects. MINOCYCLINE, LIKE OTHER TETRACYCLINE-CLASS DRUGS, CAN CAUSE FETAL HARM WHEN ADMINISTERED TO PREGNANT WOMAN. IF ANY TETRACYCLINE IS USED DURING PREGNANCY OR IF THE PATIENT BECOMES PREGNANT WHILE TAKING THESE DRUGS, THE PATIENT SHOULD BE APPRISED OF THE POTENTIAL HAZARD TO THE FETUS. SOLODYN should not be used during pregnancy or by individuals of either gender who are attempting to conceive child [see Nonclinical Toxicology (13.1) Use in Specific Populations (8.1)].THE USE OF DRUGS OF THE TETRACYCLINE CLASS DURING TOOTH DEVELOPMENT (LAST HALF OF PREGNANCY, INFANCY, AND CHILDHOOD UP TO THE AGE OF YEARS) MAY CAUSE PERMANENT DISCOLORATION OF THE TEETH (YELLOW-GRAY-BROWN). This adverse reaction is more common during long-term use of the drug but has been observed following repeated short-term courses. Enamel hypoplasia has also been reported. TETRACYCLINE DRUGS, THEREFORE, SHOULD NOT BE USED DURING TOOTH DEVELOPMENT.All tetracyclines form stable calcium complex in any bone-forming tissue. decrease in fibula growth rate has been observed in premature human infants given oral tetracycline in doses of 25 mg/kg every hours. This reaction was shown to be reversible when the drug was discontinued. Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues, and can cause retardation of skeletal development on the developing fetus. Evidence of embryotoxicity has been noted in animals treated early in pregnancy see Use in Specific Populations (8.1)]..

USE IN SPECIFIC POPULATIONS SECTION.

8USE IN SPECIFIC POPULATIONS. Minocycline like other tetracycline-class drugs can cause fetal harm when administered to pregnant woman. (5.1, 8.1) The use of drugs of the tetracycline class during tooth development may cause permanent discoloration of teeth. (5.1, 8.4). Minocycline like other tetracycline-class drugs can cause fetal harm when administered to pregnant woman. (5.1, 8.1). The use of drugs of the tetracycline class during tooth development may cause permanent discoloration of teeth. (5.1, 8.4). 8.1Pregnancy. Teratogenic Effects: Pregnancy category [see Warnings and Precautions (5.1)]SOLODYN should not be used during pregnancy. If the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus and stop treatment immediately.There are no adequate and well-controlled studies on the use of minocycline in pregnant women. Minocycline, like other tetracycline-class drugs, crosses the placenta and may cause fetal harm when administered to pregnant woman.Rare spontaneous reports of congenital anomalies including limb reduction have been reported with minocycline use in pregnancy in post-marketing experience. Only limited information is available regarding these reports; therefore, no conclusion on causal association can be established.Minocycline induced skeletal malformations (bent limb bones) in fetuses when administered to pregnant rats and rabbits in doses of 30 mg/kg/day and 100 mg/kg/day, respectively, (resulting in approximately times and times, respectively, the systemic exposure to minocycline observed in patients as result of use of SOLODYN). Reduced mean fetal body weight was observed in studies in which minocycline was administered to pregnant rats at dose of 10 mg/kg/day (which resulted in approximately the same level of systemic exposure to minocycline as that observed in patients who use SOLODYN).Minocycline was assessed for effects on peri- and post-natal development of rats in study that involved oral administration to pregnant rats from day of gestation through the period of lactation (postpartum day 20), at dosages of 5, 10, or 50 mg/kg/day. In this study, body weight gain was significantly reduced in pregnant females that received 50 mg/kg/day (resulting in approximately 2.5 times the systemic exposure to minocycline observed in patients as result of use of SOLODYN). No effects of treatment on the duration of the gestation period or the number of live pups born per litter were observed. Gross external anomalies observed in F1 pups (offspring of animals that received minocycline) included reduced body size, improperly rotated forelimbs, and reduced size of extremities. No effects were observed on the physical development, behavior, learning ability, or reproduction of F1 pups, and there was no effect on gross appearance of F2 pups (offspring of F1 animals).. 8.3Nursing Mothers. Tetracycline-class antibiotics are excreted in human milk. Because of the potential for serious adverse effects on bone and tooth development in nursing infants from the tetracycline-class antibiotics, decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother [see Warnings and Precautions (5.1)].. 8.4Pediatric Use. SOLODYN is indicated to treat only inflammatory lesions of non-nodular moderate to severe acne vulgaris in patients 12 years and older. Safety and effectiveness in pediatric patients below the age of 12 has not been established. Use of tetracycline-class antibiotics below the age of is not recommended due to the potential for tooth discoloration [see Warnings and Precautions (5.1)].. 8.5Geriatric Use. Clinical studies of SOLODYN did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease or other drug therapy.

WARNINGS AND PRECAUTIONS SECTION.

5WARNINGS AND PRECAUTIONS. The use of SOLODYN during tooth development (last half of pregnancy, infancy, and childhood up to the age of years) may cause permanent discoloration of the teeth (yellow-gray-brown). (5.1) If pseudomembranous colitis occurs, discontinue SOLODYN. (5.2) If liver injury is suspected, discontinue SOLODYN.

Evidence of embryotoxicity has been noted in animals treated early in pregnancy see Use in Specific Populations (8.1)].. 5.2Pseudomembranous Colitis. Pseudomembranous colitis has been reported with nearly all antibacterial agents and may range from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that toxin produced by Clostridium difficile is primary cause of antibiotic-associated colitis.After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to discontinuation of the drug alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against Clostridium difficile colitis.. 5.3Hepatotoxicity Post-marketing cases of serious liver injury, including irreversible drug-induced hepatitis and fulminant hepatic failure (sometimes fatal) have been reported with minocycline use in the treatment of acne.. 5.4Metabolic Effects. The anti-anabolic action of the tetracyclines may cause an increase in BUN. While this is not problem in those with normal renal function, in patients with significantly impaired function, higher serum levels of tetracycline-class drugs may lead to azotemia, hyperphosphatemia, and acidosis. If renal impairment exists, even usual oral or parenteral doses may lead to excessive systemic accumulations of the drug and possible liver toxicity. Under such conditions, lower than usual total doses are indicated, and if therapy is prolonged, serum level determinations of the drug may be advisable.. 5.5Central Nervous System Effects. Central nervous system side effects including light-headedness, dizziness or vertigo have been reported with minocycline therapy. Patients who experience these symptoms should be cautioned about driving vehicles or using hazardous machinery while on minocycline therapy. These symptoms may disappear during therapy and usually rapidly disappear when the drug is discontinued.. 5.6Benign Intracranial Hypertension. Pseudotumor cerebri (benign intracranial hypertension) in adults and adolescents has been associated with the use of tetracyclines. Minocycline has been reported to cause or precipitate pseudotumor cerebri, the hallmark of which is papilledema. Clinical manifestations include headache and blurred vision. Bulging fontanels have been associated with the use of tetracyclines in infants. Although signs and symptoms of pseudotumor cerebri resolve after discontinuation of treatment, the possibility for permanent sequelae such as visual loss that may be permanent or severe exists. Patients should be questioned for visual disturbances prior to initiation of treatment with tetracyclines. If visual disturbance occurs during treatment, patients should be checked for papilledema. Concomitant use of isotretinoin and minocycline should be avoided because isotretinoin, systemic retinoid, is also known to cause pseudotumor cerebri.. 5.7Autoimmune Syndromes. Tetracyclines have been associated with the development of autoimmune syndromes. The long-term use of minocycline in the treatment of acne has been associated with drug-induced lupus-like syndrome, autoimmune hepatitis and vasculitis. Sporadic cases of serum sickness have presented shortly after minocycline use. Symptoms may be manifested by fever, rash, arthralgia, and malaise. In symptomatic patients, liver function tests, ANA, CBC, and other appropriate tests should be performed to evaluate the patients. Use of all tetracycline-class drugs should be discontinued immediately.. 5.8Photosensitivity. Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines. This has been reported rarely with minocycline. Patients should minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using minocycline. If patients need to be outdoors while using minocycline, they should wear loose-fitting clothes that protect skin from sun exposure and discuss other sun protection measures with their physician.. 5.9Serious Skin/Hypersensitivity Reaction. Cases of anaphylaxis, serious skin reactions (e.g. Stevens Johnson syndrome), erythema multiforme, and drug rash with eosinophilia and systemic symptoms (DRESS) syndrome have been reported postmarketing with minocycline use in patients with acne. DRESS syndrome consists of cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, and one or more of the following visceral complications such as: hepatitis, pneumonitis, nephritis, myocarditis, and pericarditis. Fever and lymphadenopathy may be present. In some cases, death has been reported. If this syndrome is recognized, the drug should be discontinued immediately.. 5.10Tissue Hyperpigmentation. Tetracycline-class antibiotics are known to cause hyperpigmentation. Tetracycline therapy may induce hyperpigmentation in many organs, including nails, bone, skin, eyes, thyroid, visceral tissue, oral cavity (teeth, mucosa, alveolar bone), sclerae and heart valves. Skin and oral pigmentation has been reported to occur independently of time or amount of drug administration, whereas other tissue pigmentation has been reported to occur upon prolonged administration. Skin pigmentation includes diffuse pigmentation as well as over sites of scars or injury.. 5.11Development of Drug-Resistant Bacteria. Bacterial resistance to the tetracyclines may develop in patients using SOLODYN, therefore, the susceptibility of bacteria associated with infection should be considered in selecting antimicrobial therapy. Because of the potential for drug-resistant bacteria to develop during the use of SOLODYN, it should be used only as indicated.. 5.12Superinfection. As with other antibiotic preparations, use of SOLODYN may result in overgrowth of nonsusceptible organisms, including fungi. If superinfection occurs, SOLODYN should be discontinued and appropriate therapy instituted.. 5.13Laboratory Monitoring. Periodic laboratory evaluations of organ systems, including hematopoetic renal and hepatic studies should be performed. Appropriate tests for autoimmune syndromes should be performed as indicated.
