Summary
Antacid buffering raises gastric pH, which can change the release of pH-dependent extended-release methylphenidate capsules. This may alter the speed or extent of drug release and change the clinical effect.
What this interaction means in plain words
Aspirin / citric acid / sodium bicarbonate and Methylphenidate 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
Increased gastric pH alters the release of pH-dependent extended-release methylphenidate formulations.
What to do
Avoid giving the antacid together with extended-release methylphenidate capsules, and monitor response and adverse effects if combined use is needed.
