The Warfarin Clinical Response Panel (Aldocumar) analyzes genetic variants that determine individual sensitivity to and metabolism of this oral anticoagulant, widely used in the prevention and treatment of deep vein thrombosis, pulmonary embolism, and cardioembolic events. It evaluates the CYP2C9, CYP4F2, and VKORC1 genes, which are fundamental to the metabolic and pharmacodynamic pathway of warfarin. Variants in CYP2C9 alter the rate of drug metabolism, while polymorphisms in VKORC1 modify its sensitivity, increasing the risk of bleeding or sub-anticoagulation depending on the dose. The CYP4F2 gene influences vitamin K metabolism, modulating the overall anticoagulant response. This study allows for personalized adjustment of the initial and maintenance doses, reducing complications and optimizing therapeutic efficacy.
