PEDIATRIC USE SECTION.


Pediatric use. Safety and effectiveness in pediatric patients below years of age have not been established.

PRECAUTIONS SECTION.


PRECAUTIONS. General. Albuterol, as with all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension; in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus; and in patients who are unusually responsive to sympathomimetic amines.Clinically significant changes in systolic and diastolic blood pressure have been seen in individual patients and could be expected to occur in some patients after use of any beta-adrenergic bronchodilator.Large doses of intravenous albuterol have been reported to aggravate preexisting diabetes mellitus and ketoacidosis. As with other beta-agonists, albuterol may produce significant hypokalemia in some patients, possibly through intracellular shunting, which has the potential to produce adverse cardiovascular effects. The decrease is usually transient, not requiring supplementation.. Information for patients. The action of Albuterol Sulfate Syrup may last up to hours or longer. Albuterol Sulfate Syrup should not be taken more frequently than recommended. Do not increase the dose or frequency of albuterol sulfate syrup without medical consultation. If you find that treatment with albuterol sulfate syrup becomes less effective for symptomatic relief, your symptoms get worse, and/or you need to take the product more frequently than usual, you should seek medical attention immediately. While you are taking albuterol sulfate syrup, other asthma medications and inhaled drugs should be taken only as directed by your physician. Common adverse effects include palpitations, chest pain, rapid heart rate, and tremor or nervousness. If you are pregnant or nursing, contact your physician about use of albuterol sulfate syrup. Effective and safe use of albuterol sulfate syrup includes an understanding of the way that it should be administered.. Drug Interactions. The concomitant use of Albuterol Sulfate Syrup and other oral sympathomimetic agents is not recommended since such combined use may lead to deleterious cardiovascular effects. This recommendation does not preclude the judicious use of an aerosol bronchodilator of the adrenergic stimulant type in patients receiving Albuterol Sulfate Syrup. Such concomitant use, however, should be individualized and not given on routine basis. If regular coadministration is required, then alternative therapy should be considered.. Monoamine Oxidase Inhibitors or Tricyclic Antidepressants. Albuterol should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within weeks of discontinuation of such agents because the action of albuterol on the vascular system may be potentiated.. Beta-Blockers. Beta-adrenergic receptor blocking agents not only block the pulmonary effect of beta-agonists, such as albuterol sulfate syrup, but may produce severe bronchospasm in asthmatic patients. Therefore, patients with asthma should not normally be treated with beta-blockers. However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents in patients with asthma. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.. Diuretics. The ECG changes and/or hypokalemia that may result from the administration of nonpotassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of beta-agonists with nonpotassium-sparing diuretics.. Digoxin. Mean decreases of 16% to 22% in serum digoxin levels were demonstrated after single-dose intravenous and oral administration of albuterol, respectively, to normal volunteers who had received digoxin for 10 days. The clinical significance of these findings for patients with obstructive airway disease who are receiving albuterol and digoxin on chronic basis is unclear. Nevertheless, it would be prudent to carefully evaluate the serum digoxin levels in patients who are currently receiving digoxin and albuterol.. Carcinogenesis, mutagenesis, impairment of fertility. In 2-year study in Sprague-Dawley rats, albuterol sulfate caused significant dose-related increase in the incidence of benign leiomyomas of the mesovarium at dietary doses of 2.0, 10, and 50 mg/kg (approximately 1/2 2, and 10 times, respectively, the maximum recommended daily oral dose for adults and children, on mg/m basis). In another study this effect was blocked by the coadministration of propranolol, non-selective beta-adrenergic antagonist. In an 18-month study in CD-1 mice albuterol sulfate showed no evidence of tumorigenicity at dietary doses of up to 500 mg/kg (approximately 60 times the maximum recommended daily oral dose for adults and children on mg/m basis). In 22-month study in the Golden hamster albuterol sulfate showed no evidence of tumorigenicity at dietary doses of up to 50 mg/kg (approximately times the maximum recommended daily oral dose for adults and children on mg/m basis). 2 Albuterol sulfate was not mutagenic in the Ames test with or without metabolic activation using tester strains TA1537, TA1538, and TA98 or WP2, WP2uvrA, and WP67. No forward mutation was seen in yeast strain S9 nor any mitotic gene conversion in yeast strain JD1 with or without metabolic activation. Fluctuation assays in TA98 and E. coli WP2, both with metabolic activation, were negative. Albuterol sulfate was not clastogenic in human peripheral lymphocyte assay or in an AH1 strain mouse micronucleus assay at intraperitoneal doses of up to 200 mg/kg. S. typhimurium E. coli S. cerevisiae S. cerevisiae S. typhimurium Reproduction studies in rats demonstrated no evidence of impaired fertility at oral doses up to 50 mg/kg (approximately 15 times the maximum recommended daily oral dose for adults on mg/m2 basis).. Pregnancy. Teratogenic effects. Pregnancy Category C. Albuterol has been shown to be teratogenic in mice. study in CD-1 mice at subcutaneous (sc) doses of 0.025, 0.25, and 2.5 mg/kg (approximately 3/1000, 3/100, and 3/10, respectively, the maximum recommended daily oral dose for adults on mg/m basis), showed cleft palate formation in of 111 (4.5%) fetuses at 0.25 mg/kg and in 10 of 108 (9.3%) fetuses at 2.5 mg/kg. The drug did not induce cleft palate formation at the lowest dose, 0.025 mg/kg. Cleft palate also occurred in 22 of 72 (30.5%) fetuses from females treated with 2.5 mg/kg of isoproterenol (positive control) subcutaneously (approximately 3/10 times the maximum recommended daily oral dose for adults on mg/m basis). 2 reproduction study in Stride Dutch rabbits revealed cranioschisis in of 19 (37%) fetuses when albuterol was administered orally at 50 mg/kg dose (approximately 25 times the maximum recommended daily oral dose for adults on mg/m basis). There are no adequate and well-controlled studies in pregnant women. Albuterol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.During worldwide marketing experience, various congenital anomalies, including cleft palate and limb defects, have been rarely reported in the offspring of patients being treated with albuterol. Some of the mothers were taking multiple medications during their pregnancies. No consistent pattern of defects can be discerned, and relationship between albuterol use and congenital anomalies has not been established.. Use in Labor and Delivery. Because of the potential for beta-agonist interference with uterine contractility, use of albuterol sulfate syrup for relief of bronchospasm during labor should be restricted to those patients in whom the benefits clearly outweigh the risk.. Tocolysis. Albuterol has not been approved for the management of preterm labor. The benefit:risk ratio when albuterol is administered for tocolysis has not been established. Serious adverse reactions, including maternal pulmonary edema, have been reported during or following treatment of premature labor with beta -agonists, including albuterol. . Nursing mothers. It is not known whether this drug is excreted in human milk. Because of the potential for tumorigenicity shown for albuterol in some animal studies, decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.. Pediatric use. Safety and effectiveness in pediatric patients below years of age have not been established.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


Carcinogenesis, mutagenesis, impairment of fertility. In 2-year study in Sprague-Dawley rats, albuterol sulfate caused significant dose-related increase in the incidence of benign leiomyomas of the mesovarium at dietary doses of 2.0, 10, and 50 mg/kg (approximately 1/2 2, and 10 times, respectively, the maximum recommended daily oral dose for adults and children, on mg/m basis).

CLINICAL PHARMACOLOGY SECTION.


CLINICAL PHARMACOLOGY. studies and pharmacologic studies have demonstrated that albuterol has preferential effect on beta -adrenergic receptors compared with isoproterenol. While it is recognized that beta -adrenergic receptors are the predominant receptors in bronchial smooth muscle, data indicate that there is population of beta -receptors in the human heart existing in concentration between 10% and 50%. The precise function of these receptors has not been established (see ). In vitro in vivo 2 WARNINGS The pharmacologic effects of beta-adrenergic agonist drugs, including albuterol, are at least in part attributable to stimulation through beta-adrenergic receptors of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3, 5-adenosine monophosphate (cyclic AMP). Increased cyclic AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.Albuterol has been shown in most controlled clinical trials to have more effect on the respiratory tract, in the form of bronchial smooth muscle relaxation, than isoproterenol at comparable doses while producing fewer cardiovascular effects.Albuterol is longer acting than isoproterenol in most patients by any route of administration because it is not substrate for the cellular uptake processes for catecholamines nor for catechol- -methyl transferase. . Preclinical. Intravenous studies in rats with albuterol sulfate have demonstrated that albuterol crosses the blood brain barrier and reaches brain concentrations amounting to approximately 5.0% of the plasma concentrations. In structures outside the brain barrier (pineal and pituitary glands), albuterol concentrations were found to be 100 times those in the whole brain.Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histologic evidence of myocardial necrosis) when beta-agonists and methylxanthines are administered concurrently. The clinical significance of these findings is unknown.. Pharmacokinetics. Albuterol is rapidly absorbed after oral administration of 10 mL of Albuterol Sulfate Syrup (4 mg of albuterol) in normal volunteers. Maximum plasma concentrations of about 18 ng/mL of albuterol are achieved within hours, and the drug is eliminated with half-life of about hours.In other studies, the analysis of urine samples of patients given mg of tritiated albuterol orally showed that 76% of the dose was excreted over days, with the majority of the dose being excreted within the first 24 hours. Sixty percent of this radioactivity was shown to be the metabolite. Feces collected over this period contained 4% of the administered dose.. Clinical Trials. In controlled clinical trials in patients with asthma, the onset of improvement in pulmonary function, as measured by maximum midexpiratory flow rate (MMEF) and forced expiratory volume in one second (FEV ), was within 30 minutes after dose of Albuterol Sulfate Syrup, with peak improvement occurring between and hours. In controlled clinical trial involving 55 children, clinically significant improvement (defined as maintaining 15% or more increase in FEV and 20% or more increase in MMEF over baseline values) continued to be recorded up to hours. No decrease in the effectiveness was reported in one uncontrolled study of 32 children who took Albuterol Sulfate Syrup for 3-month period. 1.

WARNINGS SECTION.


WARNINGS. Cardiovascular Effects. Albuterol Sulfate Syrup, like all other beta-adrenergic agonists, can produce clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms. Although such effects are uncommon after administration of albuterol sulfate syrup at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, Albuterol Sulfate Syrup, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.. Deterioration of Asthma. Asthma may deteriorate acutely over period of hours or chronically over several days or longer. If the patient needs more doses of albuterol sulfate syrup than usual, this may be marker of destabilization of asthma and requires reevaluation of the patient and treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids.. Paradoxical Bronchospasm. Albuterol Sulfate Syrup can produce paradoxical bronchospasm, which may be life threatening. If paradoxical bronchospasm occurs, albuterol sulfate syrup should be discontinued immediately and alternative therapy instituted.. Use of Anti-Inflammatory Agents. The use of beta-adrenergic agonist bronchodilators alone may not be adequate to control asthma in many patients. Early consideration should be given to adding anti-inflammatory agents, e.g., corticosteroids.. Immediate Hypersensitivity Reactions. Immediate hypersensitivity reactions may occur after administration of albuterol, as demonstrated by rare cases of urticaria, angioedema, rash, bronchospasm, and oropharyngeal edema. Albuterol, like other beta-adrenergic agonists, can produce significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, symptoms, and/or electrocardiographic changes.Rarely, erythema multiforme and Stevens-Johnson syndrome have been associated with the administration of albuterol sulfate in children.
