Anti-ulcer drugs are a class of drugs, restricte of the anti-bacterial agents and it is used to treat ulcers in the stomach and the upper part of the small intestine. The three basic types of antiulcer drugs are H2-blockers, acid pump inhibitors, and mucosal paternalmedications. H2-blockers block the production of histamine, a substance that provokes acid secretion. By blocking histamine, these drugs diminish the amount of acid the stomach produces. H2-blockers generally are given for 6-8 weeks to encourage healing. If the ulcers are caused by Helicobacter pylori, and the infection is not treated, the ulcers will mostly revert and must be treated again. The H-2 receptor blocking agents, cimetidine, famotidine, nizatidine, and ranitidine have been used for this aim, but are now more widely used for upkeep therapy after handling with the proton pump inhibitors. Sucralfate, which acts by forming an overprotective covering over the ulcerate lesion. It is too used in ulcer handling and may be proper for patients in whom new classes of drugs are not indicated, or those whose gastric ulcers are caused by non-steroidal anti-inflammatory drugs quite than H. pylori infections. Histamine H-2 receptor blockers halt the activity of histamine on the gastric parietal cells. Anti-ulcer drugs are less efficient than the proton pump inhibitors. Higher rates of acidic inhibition may be achieved when the drug is administered by the intravenous road. The H-2 receptor blockers may too be used to handle heartburn and hypersecretory syndromes. When given before operation, the H-2 receptor blockers are helpful in prevention of ambition pneumonia. Acid pump inhibitors totally halt the output of abdomen acid by stopping the closing measure in acidic secretion. Omeprazole is an acidic pump inhibitor. Mucosal protective medications make a paternal barrier that allows the ulcer to heal and prevents further damage to the stomach and duodenum. Sucralfate is such a drug. Proton pump inhibitors may change the pH of the stomach. This will inactivate some antifungal drugs that expect an acid medium for effectiveness, notable itraconazole and ketoconazole. H-2 receptor blocking agents have a huge number of drug interactions. Sucralfate should not be used with aluminum accommodating antacids, because of the risk of increased aluminum absorption.
