Debrisoquin hydroxylation polymorphism was studied in 326 unrelated healthy Turkish volunteers. Debrisoquin sulfate (10 mg) was administered to subjects, and debrisoquin and 4-hydroxydebrisoquin were determined in the 0- to 8-hour urine samples. Debrisoquin oxidation was polymorphic, with 11 subjects (3.37%;
Using capillary zone electrophoresis with a phosphate buffer at pH 2.5 containing 50 mM heptakis-(2,3,6-tri-O-methyl)-beta-CD as chiral selector, the separation of the enantiomers of the main metabolite of debrisoquine (DEB), 4-hydroxydebrisoquine (4-OHDEB), is reported. For extraction of underivatized urinary DEB

Considerable unexplained intersubject variability in the debrisoquine metabolic ratio (urinary debrisoquine/4-hydroxydebrisoquine) exists within individual CYP2D6 genotypes. We speculated that debrisoquine was converted to as yet undisclosed metabolites. Thirteen healthy young volunteers, nine CYP2D6*1 homozygotes [extensive metabolizers (EMs)] and four CYP2D6*4

Previous reports of the association between the debrisoquine metabolic polymorphism and lung cancer risk have been conflicting. We examined the hypothesis that the genetically determined ability to metabolize debrisoquine identifies individuals at increased risk for lung cancer in a study

Liver transplantation or the surgical construction of portacaval shunts may radically alter an individual's debrisoquine hydroxylation capacity. Good clinical management should encompass a full awareness of such changing needs and problems in patients who undergo hepatic surgery.
