IPRATROPIUM BROMIDE AND ALBUTEROL SULFATE

INDICATIONS AND USAGE Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is indicated for the treatment of bronchospasm associated with COPD in patients requiring more than one bronchodilator.

DOSAGE AND ADMINISTRATION The recommended dose of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is one 3 mL vial administered 4 times per day via nebulization with up to 2 additional 3 mL doses allowed per day, if needed. Safety and efficacy of additional doses or increased frequency of administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution beyond these guidelines has not been studied and the safety and efficacy of extra doses of albuterol sulfate or ipratropium bromide in addition to the recommended doses of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution have not been studied. The use of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution can be continued as medically indicated to control recurring bouts of bronchospasm. If a previously effective regimen fails to provide the usual relief, medical advice should be sought immediately, as this is often a sign of worsening COPD, which would require reassessment of therapy. A Pari-LC-Plus™ nebulizer (with face mask or mouthpiece) connected to a PRONEB™ compressor was used to deliver Ipratropium Bromide and Albuterol Sulfate Inhalation Solution to each patient in one U.S. clinical study. The safety and efficacy of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution delivered by other nebulizers and compressors have not been established. Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be administered via jet nebulizer connected to an air compressor with an adequate air flow, equipped with a mouthpiece or suitable face mask.

CONTRAINDICATIONS Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is contraindicated in patients with a history of hypersensitivity to any of its components, or to atropine and its derivatives.

WARNINGS Paradoxical Bronchospasm In the clinical study of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, paradoxical bronchospasm was not observed. However, paradoxical bronchospasm has been observed with both inhaled ipratropium bromide and albuterol products and can be life-threatening. If this occurs, Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be discontinued immediately and alternative therapy instituted. Do Not Exceed Recommended Dose Fatalities have been reported in association with excessive use of inhaled products containing sympathomimetic amines and with the home use of nebulizers. Cardiovascular Effect Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, like other beta adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms. Although such effects are uncommon for Ipratropium Bromide and Albuterol Sulfate Inhalation Solution at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta agonists have been reported to produce ECG changes, such as flattening of the T-wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension. Immediate Hypersensitivity Reactions Immediate hypersensitivity reactions to albuterol and/or ipratropium bromide may occur after the administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution as demonstrated by rare cases of urticaria, angioedema, rash, pruritus, oropharyngeal edema, bronchospasm, and anaphylaxis.

Drug Interactions Anticholinergic agents Although ipratropium bromide is minimally absorbed into the systemic circulation, there is some potential for an additive interaction with concomitantly used anticholinergic medications. Caution is, therefore, advised in the co-administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution with other drugs having anticholinergic properties. β-adrenergic agents Caution is advised in the co-administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution and other sympathomimetic agents due to the increased risk of adverse cardiovascular effects. β-receptor blocking agents These agents and albuterol sulfate inhibit the effect of each other. β-receptor blocking agents should be used with caution in patients with hyperreactive airways, and if used, relatively selective β 1 selective agents are recommended. Diuretics The electrocardiogram (ECG) changes and/or hypokalemia that may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by β-agonists, especially when the recommended dose of the β-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the co-administration of β-agonist-containing drugs, such as Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, with non-potassium sparing diuretics. Monoamine oxidase inhibitors or tricyclic antidepressants Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents because the action of albuterol sulfate on the cardiovascular system may be potentiated.

ADVERSE REACTIONS Adverse reaction information concerning Ipratropium Bromide and Albuterol Sulfate Inhalation Solution was derived from the 12-week controlled clinical trial.

In the clinical trial, there was a 0.3% incidence of possible allergic-type reactions, including skin rash, pruritus, and urticaria. Additional information derived from the published literature on the use of albuterol sulfate and ipratropium bromide singly or in combination includes precipitation or worsening of narrow-angle glaucoma, acute eye pain, blurred vision, mydriasis, paradoxical bronchospasm, wheezing, exacerbation of COPD symptoms, drowsiness, aching, flushing, upper respiratory tract infection, palpitations, taste perversion, elevated heart rate, sinusitis, back pain, sore throat and metabolic acidosis. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Pregnancy TERATOGENIC EFFECTS Pregnancy Category C Albuterol sulfate Pregnancy Category C Albuterol sulfate has been shown to be teratogenic in mice. A study in CD-1 mice given albuterol sulfate subcutaneously showed cleft palate formation in 5 of 111 (4.5%) fetuses at 0.25 mg/kg (less than the maximum recommended daily inhalation dose for adults on a mg/m 2 basis) and in 10 of 108 (9.3%) fetuses at 2.5 mg/kg (approximately equal to the maximum recommended daily inhalation dose for adults on a mg/m 2 basis). The drug did not induce cleft palate formation when administered subcutaneously at a dose of 0.025 mg/kg (less than the maximum recommended daily inhalation dose for adults on a mg/m 2 basis). Cleft palate formation also occurred in 22 of 72 (30.5%) fetuses from females treated subcutaneously with 2.5 mg/kg isoproterenol (positive control). A reproduction study in Stride rabbits revealed cranioschisis in 7 of 19 (37%) fetuses when albuterol was administered orally at a dose of 50 mg/kg (approximately 55 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis). A study in which pregnant rats were dosed with radiolabeled albuterol sulfate demonstrated that drug-related material is transferred from the maternal circulation to the fetus. During worldwide marketing experience, various congenital anomalies, including cleft palate and limb defects, have been reported in the offspring of patients being treated with albuterol. Some of the mothers were taking multiple medications during their pregnancies. Because no consistent pattern of defects can be discerned, a relationship between albuterol use and congenital anomalies has not been established. Ipratropium bromide Pregnancy Category B Reproduction studies in CD-1 mice, Sprague-Dawley rats and New Zealand rabbits demonstrated no evidence of teratogenicity at oral doses up to 10, 100, and 125 mg/kg, respectively (approximately 15, 270, and 680 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis). Reproduction studies in rats and rabbits demonstrated no evidence of teratogenicity at inhalation doses up to 1.5 and 1.8 mg/kg, respectively (approximately 4 and 10 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis). There are no adequate and well-controlled studies of the use of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, albuterol sulfate, or ipratropium bromide in pregnant women. Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
