title: Debrisoquine oxidation in an Australian population.
abstract: The standard laboratory method for determination of debrisoquine phenotype has been modified and shortened with no loss of sensitivity. Debrisoquine metabolic ratios (MR) at 4 and 8 h showed excellent correlation indicating that collection time can also be shortened. Same day phenotyping is therefore possible. One hundred normal, Caucasian Australian subjects were phenotyped (46 males, 54 females) and 6% were poor metabolisers (PM) of debrisoquine. Fifty of the original subjects were also acetylation phenotyped and 34% were fast and 66% slow acetylators. One PM of debrisoquine was a fast acetylator of sulphadimidine and four PM were slow acetylators. This was a non-significant association.
