title: Intravenous N-acetylcysteine, hepatotoxicity and plasma glutathione S-transferase in patients with paracetamol overdosage.
abstract: The concentration of glutathione S-transferase B1 (GST B1) subunits was measured in sequential plasma samples taken at frequent intervals for 48 h from ten patients with severe paracetamol poisoning who were treated with intravenous N-acetylcysteine. No significant increase in plasma GST B1 concentration was observed over the study period and with 4 h of starting treatment with N-acetylcysteine there were significant decreases in plasma GST B1 concentrations. None of the patients subsequently developed significant liver damage. At the dose used for the treatment of paracetamol poisoning, N-acetylcysteine has no hepatotoxic effects.
