Summary
Urinary paracetamol metabolites from Sprague-Dawley and Wistar rats were analysed by reversed-phase HPLC. Variations in the metabolic profile were observed as a function of dose, age, sex, species and route of administration. In addition the effect of 3-methylcholanthrene as an inducer of cytochrome P450 mixed function oxidase on paracetamol metabolism was also studied. Increased oxidative metabolism which lead to the formation of 3-thiomethylparacetamol conjugates along with paracetamol mercapturic acid could be correlated with increased susceptibility to hepatic demage. Furthermore it appears that the length of time taken for excretion and the level of free drug excreted may be involved in the aetiology of chronic renal damage.
