Descripción

Ibuprofen combined with SSRIs markedly increases the risk of GI bleeding through synergistic impairment of platelet function and gastric mucosal defense.

Mecanismo

SSRIs deplete serotonin in platelets, reducing aggregation; ibuprofen inhibits COX-1–mediated thromboxane A2 synthesis and damages gastric mucosa. Both effects converge to heighten GI hemorrhage risk.

Relevancia clínica

Epidemiological data show a 15-fold increase in upper GI bleed risk with NSAID + SSRI, compared with a 3-fold increase for each alone.

Manejo clínico

Avoid combination if possible; if co-administration is necessary, add a PPI and use the lowest NSAID dose for the shortest duration.
