General description

Warfarin is an antagonist of vitamin K. It is an oral coumarin anticoagulant.

Application

(S)-(−)-Warfarin has been used in cell cultures.
Studies using (R)-(+)-warfarin have reported that it can upregulate hepatic CYP3A4 and CYP2C. It has also been used in HepG2 cells to study protein profiles.

Biochem/physiol Actions

Warfarin is used to regulate and inhibit thromboembolic disorders. The CYP2C9 (cytochrome P450 family 2 subfamily C member 9) protein plays a major role in the inactivation of potent S-warfarin.
CYP2C9 substrate; anticoagulant.

Packaging

warfarin is a commonly prescribed oral anticoagulant with narrow therapeutic index. It interferes with the vitamin K cycle to achieve anti-coagulating effects. Warfarin has two enantiomers, S(-) and R(+) and undergoes stereoselective metabolism, with the S(-) enantiomer being more effective.

Warfarin, an antagonist of vitamin K, is an oral coumarin anticoagulant widely used to control and prevent thromboembolic disorders. Warfarin is clinically available as a racemic mixture of R- and S-warfarin. The S-enantiomer has three to five times greater anticoagulation
