Summary
Famotidine raises gastric pH, which accelerates release of delayed-release risedronate and alters its absorption. Both ibuprofen and bisphosphonates can irritate the upper gastrointestinal tract.
What this interaction means in plain words
Ibuprofen / famotidine and Risedronate 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
Elevated gastric pH alters pH-dependent dissolution of delayed-release risedronate, changing its absorption.
What to do
Use immediate-release risedronate instead of the delayed-release form with acid suppression, and monitor for upper gastrointestinal symptoms.
