Summary
Cholinesterase inhibitors increase gastric acid secretion and may promote GI irritation, which adds to the mucosal injury risk from aspirin. Rectal aspirin still has systemic salicylate effects, so ulcer and bleeding risk can be additive.
What this interaction means in plain words
Aspirin rectal and Rivastigmine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive GI toxicity from cholinergic stimulation of gastric acid secretion and salicylate-induced mucosal injury.
What to do
Watch for dyspepsia, melena or GI bleeding, especially with long-term or higher-dose aspirin; consider gastroprotection in high-risk patients.
