An algorithm for managing warfarin resistance
WebMay 20, 2024 · Warfarin is an oral anticoagulant widely used to treat and prevent thromboembolic diseases. 1 Because warfarin has a narrow therapeutic index, effective dosing of this drug requires frequent anticoagulation monitoring and dose adjustments. WebApr 15, 2008 · Because of historically high rates of drug-associated adverse events, warfarin remains underprescribed. Further, interindividual variability in therapeutic dose mandates frequent monitoring until target anticoagulation is achieved. Genetic polymorphisms involved in warfarin metabolism and sensitivity have been implicated in variability of dose. hannah drake article
Heart Failure, COPD Exacerbations Elevate Warfarin Sensitivity
WebThe recently discovered enzyme VKORC1 of the vitamin K cycle, which is the target for the anticoagulant drug warfarin, has opened new opportunities to understand warfarin resistance and biosynthesis of vitamin K-dependent blood coagulation factors and other members of this protein family. WebThe CYP2C9 enzyme breaks down (metabolizes) compounds including steroid hormones and fatty acids. The CYP2C9 enzyme also plays a major role in breaking down the drug warfarin, which thins the blood and prevents blood clots from forming. This enzyme also assists in metabolizing other drugs such as ibuprofen, which reduces inflammation. WebNov 16, 2006 · Warfarin doses (mean ± SD) were compared across groups by analysis of variance (ANOVA). Frequencies of CYP2C9, VKORC1, and Asp36Tyr variants in the warfarin-resistant and -sensitive groups and in the control group were compared by χ 2 and Fisher exact tests. In the controls, logistic regression was used to evaluate the effect of age, … cgi password reset
