Comparative histological and histochemical studies between ranitidine and nizatidine in treatment of peptic ulcer with evaluation of their adverse effects on male sex hormones

Abstract

Peptic ulcer is an excoriated area of stomach or intestinal mucosa. Two experimental designs were proceeded: the first aimed. on twenty adult male albino rats, used to study the protective effect of both ranitidine and nizatidine; on the second, including sixty adult male albino rats, was used to study the therapeutic effect of ranitidine and nizatidine after induction of ulcer and also to evaluate the adverse effects of therapeutic doses of H2-receptor antagonists on male hormonal profile. The study aims to assess the gastroprotective effects of nizatidine and ranitidine and on treating of non-steroidal anti-inflammatory drugs (NSAIDs) induced peptic ulcer and to evaluate its adverse effect on male sex hormones. The result revealed that ranitidine and nizatidine reduced incidence of ulceration. Histopathological findings showed a significant recovery of the alteration, and disturbance in male sex hormones. Nizatidine is better than ranitidine in the management of NSAIDs induced peptic ulcer in rats.
