Drug Interactions
Altered prothrombin time and increased serum concentration with coumarin anticoagulants (e.g. warfarin). May reduce the excretion and increase plasma concentrations of procainamide and N-acetylprocainamide (high dose ranitidine). May alter the absorption of pH-dependent drugs which may result in either an increase in absorption (e.g. triazolam, glipizide, midazolam) or decrease in absorption (e.g. atazanavir, gefitnib, ketoconazole, delaviridine). Decreased absorption with co-administration of high dose sucralfate.
