Albuterolinteractions

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 coadministration of ipratropium bromide and albuterol sulfate with other drugs having anticholinergic properties. ß-adrenergic agents: Caution is advised in the coadministration of ipratropium bromide and albuterol sulfate and other sympathomimetic agents due to the increased risk of adverse cardiovascular effects. ß-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 β1 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 coadministration of β-agonist-containing drugs, such as ipratropium bromide and albuterol sulfate, with non-potassium sparing diuretics. Monoamine oxidase inhibitors or tricyclic antidepressants: Ipratropium bromide and albuterol sulfate 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.
