β¦ Synopsis
Investigations in animals have suggested that conjugation of paracetamol may be reduced in malaria. We have measured plasma concentrations and the urinary excretion of paracetamol and its phase II metabolites in eight Thai patients during uncomplicated falciparum malaria and in convalescence, following a 1000 mg single oral dose.
The apparent oral clearance (Malaria, 3.6; Convalescence, 3.9; ml. min -1. kg-1), the elimination half-life (Malaria, 3.8; Convalescence, 3.7 h) and apparent volume of distribution (Malaria, 1.2; Convalescence, 1.2; 1. kg -1) of paracetamol were similar during malaria and convalescence. In addition, the urinary excretion of paracetamol and its major phase II metabolites and their formation clearances from paracetamol were not significantly different between the two study phases.
These data show that clinical malaria infection has no effect on the conjugation of paracetamol in man.

We have compared the disposition of oral paracetamol (1.0 g t.d.s. for 10 days) in 6 healthy volunteers and 6 conservatively-managed patients with chronic renal failure (mean plasma creatinine 451 mumol.l-1). Blood was sampled daily for 10 days before the morning dose of paracetamol. Each day the pr
