The Role of Alpha-2 Adrenergic Receptors in Anti-ulcer Activity

Abstract

Abstract

Although peptic ulcer disease has long been recognized, the proposed mechanisms of its etiopathogenesis change every year. This review shows that gastric ulcers have a significant relationship with alpha-2 adrenergic receptors. The aggravating factors of gastric ulcer formation have been reported to act by blocking alpha-2 adrenergic receptors, whereas drugs possessing anti-ulcer activity have been shown to ensure gastric protection by stimulating the alpha-2 adrenergic receptors. The data derived from the literature indicate the likelihood that any drug or substance selectively stimulating the alpha-2 adrenergic receptors may possess anti-ulcer activity.
