:(±)-Varfarina
Descrição:
(±)-Varfarina é um anticoagulante sintético comumente utilizado na prevenção e tratamento de distúrbios tromboembólicos. Funciona inibindo a epóxido redutase da vitamina K, que é essencial para a síntese de fatores de coagulação dependentes da vitamina K no fígado. Este composto existe como uma mistura racêmica de dois enantiômeros, R e S, sendo o enantiômero S significativamente mais potente como anticoagulante. A varfarina é caracterizada por sua relativamente baixa solubilidade em água, mas é solúvel em solventes orgânicos, o que facilita sua formulação em várias preparações farmacêuticas. A substância tem uma fórmula molecular de C19H16O4 e um peso molecular de aproximadamente 308,34 g/mol. Sua farmacocinética envolve administração oral, com um início de ação retardado devido ao tempo necessário para que os fatores de coagulação existentes diminuam. A varfarina está sujeita a uma variabilidade interindividual significativa na dosagem devido a fatores como polimorfismos genéticos, ingestão dietética de vitamina K e interações com outros medicamentos, exigindo monitoramento cuidadoso dos parâmetros de coagulação durante a 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%Cor e Forma:White Slightly Brown Clear LiquidPeso molecular:308.33 g/molWarfarin
CAS: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.Fórmula:C19H16O4Pureza:99.35%Cor e Forma:SolidPeso molecular:308.3279
