คำอธิบาย
Fluoxetine may reduce clopidogrel's antiplatelet efficacy by inhibiting CYP2C19-mediated bioactivation while also independently impairing platelet serotonin-mediated aggregation.
กลไก
Fluoxetine and norfluoxetine inhibit CYP2C19, reducing clopidogrel activation; paradoxically, fluoxetine's platelet serotonin depletion may partially offset this, but the net antiplatelet effect is uncertain.
ความสำคัญทางคลินิก
The clinical outcome impact is not well quantified; caution is warranted in high-risk cardiovascular patients on clopidogrel.
การจัดการ
Prefer escitalopram or sertraline (weaker CYP2C19 inhibition) when an SSRI is needed alongside clopidogrel.
