Histological, histochemical and immunohistological comparative study between Ranitidine and Rebamipide in Gastric Mucosal protection after Dexamethasone induced injury in adult male albino rats

ABSTRACT

Background: Gastritis can be caused by many factors, one of them is drugs, and among these drugs is dexamethasone that has many uses in medicine. Dexamethasone prevent synthesis of gastric mucous barrier by surface epithelial cells, so the stomach wall will be injured by digestive enzymes and stomach HCl. Treatment of gastritis can be done by antisecretory drugs like H2 receptors blocker as ranitidine or by drugs that stimulate prostaglandins synthesize by surface epithelial cells of gastric mucosa to form the mucous barrier like rebamipide
