Effects of amodiaquine hydrochloride and artemisinin on indomethacin-induced lipid peroxidation in rats

In this study, the effects of two antimalarials-amodiaquine hydrochloride and artemisinin were investigated in ulcerated albino rats of Wistar strain. Rats were treated with amodiaquine (30 mg kg-1) and Artemisinin (2.86 mg kg-1) for 24 h after formation of ulcers induced by indomethacin. Treatments with Amodiaquine Hydrochloride led to significantly increased gastric lesions while artemisinin led to significantly decreased gastric lesions. Also, amodiaquine hydrochloride seemed to elaborate the indomethacin induced effects on gastric juice volume, pH and acid output, while artemisinin attenuated these changes. The data indicates that the use of amodiaquine hydrochloride may be dangerous to the integrity of the stomach, especially in existing gastric ulcers, while artemisinin is mild and ameliorating, may result from their lipid peroxidation/apoptosis activity interference. © 2008 Asian Network for Scientific Information.
