Summary
Acid suppression can change the release of pH-dependent extended-release methylphenidate formulations, which may alter drug exposure and the speed of onset. The effect varies by product and is usually modest.
What this interaction means in plain words
Methylphenidate and Omeprazole have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Methylphenidate belongs to Central Nervous System; Omeprazole belongs to Gastrointestinal Tract.
Why it happens
Raised gastric pH alters the dissolution of pH-dependent coatings in some extended-release methylphenidate products.
What to do
Monitor clinical response to methylphenidate when a PPI is started or stopped. Consider a non-pH-dependent formulation if response becomes erratic.
