Polymorphic paracetamol conjugation: phenotyping in a Hungarian population.

The authors studied the distribution of the paracetamol conjugation in a Hungarian population (53 adult Caucasian persons). The data indicated that the excretion of paracetamol glucuronide and sulphate were not normally distributed. Bimodality were apparent in both conjugation pathways: 15.1% of subjects was relatively extensive glucuronidators, and the 24.5% of subjects was extensive sulphatators. Monitoring the ratios of various urinary paracetamol conjugates/paracetamol may be useful as a tool for determining the glucuronide and sulphate conjugation capacity in humans.
