Little is known regarding the biotransformation of drugs in Down's syndrome. In particular, there are no published studies that examine metabolic pathways such as N-acetylation, which can exhibit genetically-determined variability. The objective of the present investigation was to compare the

The human acetylation genotype was determined by measuring urinary caffeine metabolites by use of a modification of a previously published HPLC method. The problem of separation of 7-methylxanthine (7X) from 1-methyluric acid (IU) in urine extracts was achieved by adding

p-Phenylenediamine (PPD) has been widely distributed as hair dye ingredient and may be responsible for contact dermatitis. Since not all the subjects exposed to PPD react to the substance, we tested a possible predisposing factor of cutaneous drug metabolism. Eighty-five

The use of two caffeine metabolite ratios for acetylator phenotyping was validated by demonstrating concordance with two sulfamethazine tests in 178 unrelated healthy subjects. The caffeine metabolites used for this purpose were 5-acetylamino-6-amino-3-methyluracil (AAMU), 1-methylxanthine (1X), and 1-methylurate (1U). The

Previously published methods allow the determination of the genetically controlled acetylator status using caffeine as a test drug, based on the urinary excretion of a ring-opened metabolite of caffeine, an acetylated uracil (5-acetylamino-6-formylamino-3-methyluracil). 5-Acetylamino-6-formylamino-3-methyluracil is labile but can be converted
