Sintesi

Omeprazole inhibits CYP2C19, reducing clopidogrel’s bioactivation and antiplatelet effect, which may increase risk of thrombotic/cardiovascular events.

Cosa significa questa interazione in parole semplici

Clopidogrel and Omeprazole can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Clopidogrel belongs to Cardiovascular; Omeprazole belongs to Gastrointestinal Tract.

Livello di evidenza: High

Perché avviene

CYP2C19 inhibition by omeprazole decreases formation of clopidogrel’s active metabolite → reduced platelet inhibition.

Cosa fare

Avoid coadministration. Use an alternative acid suppressant (e.g., pantoprazole) or consider a non–CYP2C19-dependent P2Y12 inhibitor when appropriate.

Cosa chiedere al farmacista
