:(±)-Warfarina
Descripción:
(±)-Warfarina es un anticoagulante sintético comúnmente utilizado en la prevención y tratamiento de trastornos tromboembólicos. Funciona inhibiendo la epóxido reductasa de vitamina K, que es esencial para la síntesis de factores de coagulación dependientes de vitamina K en el hígado. Este compuesto existe como una mezcla racémica de dos enantiómeros, R y S, siendo el enantiómero S significativamente más potente como anticoagulante. La warfarina se caracteriza por su relativamente baja solubilidad en agua, pero es soluble en disolventes orgánicos, lo que facilita su formulación en varias preparaciones farmacéuticas. La sustancia tiene una fórmula molecular de C19H16O4 y un peso molecular de aproximadamente 308.34 g/mol. Su farmacocinética implica administración oral, con un inicio de acción retrasado debido al tiempo requerido para que los factores de coagulación existentes disminuyan. La warfarina está sujeta a una variabilidad interindividual significativa en la dosificación debido a factores como polimorfismos genéticos, ingesta dietética de vitamina K e interacciones con otros medicamentos, lo que requiere un monitoreo cuidadoso de los parámetros de coagulación durante la terapia.

CAS:<p>Warfarin is a coumarin that is used as an oral anticoagulant. It has been in use for over 50 years and is still the most widely prescribed drug for the prevention of thromboembolic disease. Warfarin inhibits the synthesis of vitamin K-dependent clotting factors II, VII, IX, and X. This inhibition leads to a prolonged prothrombin time and increased bleeding time. Warfarin also prevents blood from clotting by inhibiting platelet aggregation. The molecular weight of Warfarin is 798 Da, which corresponds to its molecular weight heparin (MWH) binding site.<br>Warfarin has a narrow therapeutic window and requires careful monitoring by measuring prothrombin time in order to prevent adverse effects such as excessive bleeding or blood clots. Warfarin also interacts with many drugs, including aspirin and non-steroidal anti-inflammatory drugs like ibuprofen, which can lead to increased risk of bleeding</p>Fórmula:C19H16O4Pureza:Min. 95%Forma y color:White Slightly Brown Clear LiquidPeso molecular:308.33 g/molWarfarin
CAS:<p>Warfarin (Coumafene) is a vitamin K antagonist, and it works by blocking the action of vitamin K, which is necessary for the synthesis of clotting factors in the liver. Warfarin blocks the action of vitamin K by inhibiting the enzyme gamma-glutamyl carboxylase, which is responsible for the carboxylation of glutamate residues in the clotting factors. This prevents the production of functional clotting factors, leading to an anticoagulant effect.</p>Fórmula:C19H16O4Pureza:99.35%Forma y color:SolidPeso molecular:308.3279
