Delayed absorption and increased peak serum concentration with propantheline bromide. Ranitid 75 mg/5 ml 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.
