Clotting factors inhibited by warfarin

WebTwo major genes are involved in warfarin pharmacogenomics: CYP2C9 and VKORC1 (VKORC1; vitamin K epoxide reductase complex). CYP2C9 metabolizes warfarin to an inactive metabolite. VKORC1 is the molecular target inhibited by warfarin, thus reducing the production of vitamin K-dependent clotting factors. WebThe effect of warfarin is influenced by many factors. These include the dose, patient compliance, diet and vitamin K status, various lifestyle factors such as alcohol intake, concomitant medications which affect the metabolism of warfarin, and comorbid illness especially liver and cardiac disease.
