Interaction of Alin 150 mg
Delayed absorption and increased peak serum concentration with propantheline bromide. Alin 150 mg minimally inhibits hepatic metabolism of coumarin anticoagulants, theophylline, diazepam and propanolol. May alter absorption of pH-dependent drugs (e.g. ketoconazole, midazolam, glipizide). May reduce bioavailability with antacids.
