Sodium bicarbonate enhances the absorption of propantheline in man

  • D. Mark Chaput de Saintonge
  • Andrew Herxheimer


Sodium bicarbonate (5 g) significantly increased the effects of simultaneously administered 45–60 mg propantheline on heart rate and saliva flow. An equivalent dose of sodium chloride (3.2 g) given with propantheline was without effect. This interaction is likely to affect patients taking both an antacid and an anticholinergic drug.
