B01AA04 - Phenprocoumon |
Propably not porphyrinogenic |
PNP |
Rationale
Phenprocoumon is metabolized by CYP 2C9, 3A4 and 2C8, but induction or inhibition of the CYP enzymes are not observed or suspected.
Chemical description
Phenprocoumon is a coumarin derivate.
Therapeutic characteristics
Phenprocoumon is a vitamin K antagonist that acts as a long acting oral anticoagulant.
It is administered orally and has a half- life of 5-9 days (Ufer 2004).
Metabolism and pharmacokinetics
In vitro, CYP2C9 and CYP3A4 is found to be the main catalyzing enzymes of the R-enantiomer of phenprocoumon hydroxylation while CYP 2C8 has part in the hydroxylation of the S-enantiomer (Ufer 2004, 2005).
No CYP relevant drug-drug interaction with phenprocoumon as a perpetrator has been reported in the literature (Drugbank, Lexi-Interact, Micromedex, SPC).
