1. Dapsone is a potent anti-inflammatory and anti-parasitic compound, which is metabolised by cytochrome P-450 to hydroxylamines, which in turn cause methaemoglobinaemia and haemolysis. However, during the process of methaemoglobin formation, erythrocytes are capable of detoxifying the hydroxylamine
Methemoglobinemia and hemolysis are the most prominent side-effects of exposure to a wide variety of arylamine drugs, including agricultural and industrial chemicals. Recent studies with aniline and dapsone have identified N-hydroxyl metabolites as the red blood cell (RBC) mediators. This study
We have previously shown that cimetidine, given concurrently for 2 weeks to patients on chronic dapsone therapy, reduced methaemoglobinaemia by inhibiting the formation of the toxic hydroxylamine metabolite of dapsone. The aim of the present study was to examine the effect of this combination on the
