title: Paracetamol metabolism in pregnancy.
abstract: Paracetamol disposition was studied in groups of pregnant and non-pregnant women of comparable age. Paracetamol apparent oral clearance was 58% higher and elimination half-life was 28% lower in the pregnant women compared to the control group. The higher clearance in the pregnant women was due to increased activity of the glucuronidation (75% higher) and oxidative (88% higher) pathways of paracetamol metabolism. There was no difference between the two groups in paracetamol sulphation or renal clearance of unchanged drug.
