Identification
- Generic Name
- (S)-Warfarin
- DrugBank Accession Number
- DB14055
- Background
Warfarin consists of a racemic mixture of two active enantiomers—R- and S- forms—each of which is cleared by different pathways. S-warfarin is 2-5 times more potent than the R-isomer in producing an anticoagulant response.1
