Abstract
The potential role of sodium sulphate in possible enhancement of the hepatoprotective action of N-acetylcysteine (NAC) in paracetamol (PCM) overdose was examined. The effects of sodium sulphate (200 mg/kg) in combination with NAC (400 mg/kg) administered intraperitoneally 2 h post-PCM dose, on mortality rate and plasma activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were investigated in mice 24 h after receiving a single oral dose of 400 mg/kg PCM. In addition, the effect on the mortality rate of PCM-treated animals of co-administering 400 mg/kg sodium sulphate with NAC (200 or 400 mg/kg) was also studied. NAC alone caused a marked reduction in the mortality rate of PCM-treated mice and a sharp drop in their plasma AST and ALT activities to near normal values. However, no additional reduction in plasma levels of AST and ALT was observed when sodium sulphate was co-administered with NAC. Similarly, sodium sulphate (200 mg/kg) administered alone to PCM-treated mice had no effect on the high mortality rate or the elevation in plasma AST and ALT activities observed in these animals. Furthermore, increasing the dose of sodium sulphate to 400 mg/kg did not influence the mortality rate. It is therefore concluded that sodium sulphate neither protects against paracetamol-induced hepatotoxicity nor enhances the hepatoprotective action of N-acetylcysteine.
