Reactive oxygen species (ROS) have been implicated in the etiology of indomethacin-induced gastric mucosal damage. This study investigated amiodarone's protective effects against oxidative gastric mucosal damage induced by indomethacin. Amiodarone is a widely used antiarrhythmic agent. We have investigated alterations in the glutathione level, and the activities of antioxidative enzymes [superoxide dismutase, catalase, glutathione s-transferase glutathione reductase and myeloperoxidase], as markers for ulceration process following oral administration of amiodarone and ranitidine in rats with indomethacin-induced ulcers. In the present study we found that 1) amiodarone, lansoprazole and ranitidine reduced the development of indomethacin-induced gastric damages, at a greater magnitude for amiodarone and lansoprazole than for ranitidine; 2) amiodarone and ranitidine alleviated increases in the activities of catalase and glutathione s-transferase enzymes resulting from ulcers; 3) amiodarone and ranitidine ameliorated depressions in the glutathione level and the activities of superoxide dismutase and glutathione reductase enzymes caused by indomethacin administration; and 4) all doses of amiodarone amplified the myeloperoxidase activity resulting from indomethacininduced gastric ulcers. The results indicate that the gastroprotective activity of amiodarone, which may be linked to its intrinsic antioxidant properties, cannot be attributed to its effect on myeloperoxidase activity.
