설명

Aspirin combined with fluoxetine increases GI hemorrhage risk through synergistic platelet impairment and CYP2C9-mediated interactions.

기전

Fluoxetine depletes platelet serotonin and inhibits COX-2 at higher concentrations; aspirin inhibits COX-1. Both reduce platelet aggregation through different but additive mechanisms.

임상적 중요성

Epidemiological studies document a 3- to 5-fold increase in upper GI bleed risk with combined antiplatelet + SSRI.

관리 방법

Co-prescribe a PPI; counsel patients on GI bleeding signs; use the lowest effective dose of each agent.
