摘要: Warfarin and other oral vitamin K antagonists (VKAs) have been the primary pharmacologic options with well-established efficacy data in high-risk patient populations. dose requirements to achieve therapeutic anticoagulation are highly variable. This variability response results increased risk for adverse events, including thromboembolism bleeding. Genetic variants CYP2C9 VKORC1 identified shown explain some of warfarin response. Prospective trials suggest that incorporation genotype faster time range than without; however, whether these improvements result improved clinical outcomes is unclear. The target-specific anticoagulants alternatives do not require laboratory monitoring. Some pharmacogenetic variation their may exist as well. Ongoing will provide a clearer picture genotype-based dosing improves may, therefore, subsequently be compared agents.
