title: Ifosfamide plasma clearance in relation to polymorphic debrisoquine oxidation.
abstract: Ifosfamide (IF) pharmacokinetics and the plasma (NBP)-alkylating activity were determined in 33 patients with different tumours after the administration of IF as single-agent chemotherapy. All subjects had been phenotyped for debrisoquine oxidation. There is a lack of correlation between the debrisoquine metabolic ratio (DMR) and either the total plasma clearance of IF (CLIF) or the AUC of the plasma NBP-alkylating activity.
