Sucralfate in the prevention of acute gastric lesions induced by ischemia-reperfusion.

The role of Sucralfate in prevention of acute gastric injuries and its comparison with free radicals blockers as Allopurinol, Soybean Trypsin Inhibitor and Superoxide Dismutase was studied in the ischemia-reperfusion model by total occlusion of the celiac axis in Wistar rats. In control rats, the gross gastric mucosal necrotic area was of 80%; in contrast, the antioxidant drugs resulted in a necrotic area of 7%-15% and Sucralfate resulted in a necrotic area of only a 4%. It was concluded that Sucralfate, as antioxidant-cytoprotective drug, by enhancing the gastric defensive barrier was more important than the secondary aggression induced by free radicals.
