Omeprazole (30 mg/kg i.g.) famotidine (1 mg/kg, i.g.) and nitrendipine (16 mg/kg, i.p.) significantly prevented gastric ulceration. Nitrendipine reduced the mucus secretion and exhibited no important change in phospholipid content; thus, it failed to restore the damage in the gastric mucosal barrier due to cold-restraint stress. Omeprazole increased mucus secretion and phospholipid content of gastric mucosal barrier whereas famotidine tended to cause an increase in mucus and phospholipid levels; however, this difference did not attain statistical significance. Serum gastrin levels revealed lower values in the nitrendipine group as compared with controls; whereas it increased in omeprazole and famotidine groups, but more significantly in the omeprazole treated group.eninfo:eu-repo/semantics/closedAccessFamotidineNitrendipineOmeprazoleStress UlcerArticle221152-s2.0-0027936047Q1
