| B01AA07 - Acenocoumarol | Propably not porphyrinogenic | PNP | 
Rationale
Acenocoumarol is metabolized by CYP 2C9, 1A2 and 2C19, but induction or inhibition of the CYP enzymes are not observed or suspected. 
    Chemical description
Acenocoumarol is a coumarin derivate.
    Therapeutic characteristics
Acenocoumarol is a coumarin derivative and functions as vitamin K antagonist. It is used in the treatment and prevention of thromboembolic diseases.
It is administered orally and the elimination half-life from the plasma is from 8 to 11 hours.
    
    Metabolism and pharmacokinetics
Acenocoumarol is metabolized mainly by CYP 2C9, but CYP1A2 and CYP 2C19 are also involved (Thijssen 2000, Ufer 2005).
No CYP relevant drug-drug interaction with acenocoumarol as a perpetrator has been reported in the literature (Lexi-Interact, Micromedex, SPC).
    
    
    
    IPNet drug reports
