Ud over den aktive metabolit dannes inaktive metabolitter, herunder 2 hovedmetabolitter dannet ved hydroxylering af butylsidekæden og en metabolit af mindre betydning, en N- 2- tetrazolglucuronid.
In addition to the active metabolite, inactive metabolites are formed, including two major metabolites formed by hydroxylation of the butyl side chain and a minor metabolite, an N-2 tetrazole glucuronide.
