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.

WebApr 14, 2024 · The inhibition of FXa by CSL is depicted in the Lineweaver–Burk plots in Figure 5 A (inset), which shows a mixed-type inhibitory pattern. CSL induced a decrease in the V max, with a concomitant increase in the K m value of FXa on S-2222. We discovered that CSL inhibited FXa activity toward S-2222 at a K value of 3.71 μM. ( Table 2 ). WebMay 8, 2024 · These actions render clotting factors inactive and unable to participate in the clotting cascade. Warfarin's hepatic metabolism and protein binding are the most common mechanisms for the occurrence of drug-drug interactions. Warfarin is metabolized via the cytochrome P450 system by CYP 2C9, 1A2, and 3A4. WebLabel This is thought to be due to warfarin's inhibition of vitamin K recycling as VKA is needed for the carboxylation of matrix Gla protein. 13 This protein is an anti-calcification factor and its ...
