만성 신부전 환자에서 clopidogrel에 의해 유발된 호중구감소증 1예

Clopidogrel, a thienopyridine derivative, is an anti-platelet agent that acts as an antagonist of the platelet adenosine diphosphate receptor and considered for essential prophylaxis for intracoronary stent thrombosis in the treatment of ischemic heart disease. Clopidogrel is considered as safe as aspirin but a few cases of severe hematologic adverse reactions associated with clopidogrel had been reported such as neutropenia, aplastic anemia, thrombocytopenic purpura, and thrombocytopenia. We report a rare case of neutropenia induced by clopidogrel in chronic renal failure in a patient who underwent percutaneous coronary intervention.
