Warfarin Sodium Tablets￥51.90 Warfarin Sodium Tablets are dicoumarin derivatives with a chemical structure of 3-(a-phenyl acetone)-4-hydroxycoumarin. It has no anticoagulant effect in vitro and mainly inhibits the synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X in liver microsomes. Warfarin sodium tablets are indirect-acting coumarin oral anticoagulants. By inhibiting vitamin K from synthesizing coagulation factors II, VII, IX, and X in liver cells, it exerts an anticoagulant effect. The carboxylase in liver microsomes can convert the glutamate of the above-mentioned coagulation factors into γ-carboxyglutamic acid, which is then combined with calcium ions to exert its coagulation activity. The manufacturer of Warfarin Sodium Tablets is the Finnish Orion Company. It is an imported drug and is much more expensive than the domestically produced drug.
