Changes in microsomal drug oxidizing enzymes, microsomal lipids, hepatic glutathione (GSH), glutathione S-transferase (GST) and malondialdehyde (MDA) formation following administration of rats with therapeutic doses of three structurally related antimalarial drugs, amodiaquine (AQ). mefloquine (MQ) and halofantrine (HF) were investigated. There was a significant decrease in the activities of aniline hydroxylase, p-nitroanisole O-demethylase and pentoxyresorufin O-dealkylase in AQ, MQ and HF treated rats. AQ elicited the greatest effect with 50, 37 and 67% reductions in the activities of aniline hydroxylase, p-nitroanisole O-demethylase and pentoxyresorufin O-dealkylase, respectively. All the drugs prolonged hexobarbital-sleeping time to varying extents. The three drugs increased significantly the cholesterol pet phospholipid ratio. AQ, MQ and HF decreased significantly the GSH level, GST activity and increased the formation of MDR. The results indicate that the alterations in hepatic microsomal components and lipid peroxidation caused by the antimalarials are related to the structural differences in the compounds.
