Research has found that the majority of peptic ulcers are caused by an infection with a bacterium called Helicobacter pylori (H. pylori), and standard treatment in these cases is a combination of drugs, including antibiotics and a proton pump inhibitorPeptic ulcers are open sores or erosions in the lining of either the duodenum (duodenal ulcers) or the stomach (gastric ulcers). The duodenum is the first part of the small intestine. Contrary to popular belief, ulcers are not caused by spicy food or stress but instead are most commonly due to either an infection or long-term use of certain medications. The main goals for treating a peptic ulcer include eliminating the underlying cause (particularly H. pylori infection or use of NSAIDs), preventing further damage and complications, and reducing the risk of recurrence. The discovery of the link between ulcers and H. pylori has resulted in a new treatment option. Now, in addition to treatment aimed at decreasing the production of stomach acid, doctors may prescribe antibiotics for patients with H. pylori. By eliminating H. pylori means the ulcer may now heal and most likely will not come back. However, antibiotics alone are not used to treat H Pylori. The most commonly recommended first-line treatment is a combination of a proton pump inhibitor and the antibiotics amoxicillin and clarithromycin for two weeks. In penicillin allergic people, a drug called metronidazole is sometimes substituted for the amoxicillin. Medication is almost always needed to alleviate symptoms and must be used to eradicate H. pylori. Surgery is required for certain serious or life-threatening complications of peptic ulcers and may be considered if medications are not working. Key words: Peptic Ulcerative Disorder.

It usually presents after the age of therapy for H. pylori eradication consists of a proton 15 and is equally common in both sexes. The currently pump inhibitor with either clarithromycin and most widely accepted causative agent is H. pylori. amoxicillin or clarithromycin and metronidazole. Approximately 95% of duodenal ulcers and 70% of Although many combinations and treatment durations gastric ulcers are associated with H. pylori (but only have been proposed, the most effective are the twice- 15% of H. pylori colonized individuals will develop daily dosing, 1-week duration regimens such as peptic ulcer disease).

Peptic ulceration is also more common in eradication regimens progressively change due to patients on NSAIDs (Non Steroidal Anti Inflammatory failure rates associated with the development of Drugs) (36%) as compared to patients who are not on antibiotic-resistant strains of H. pylori.

However, the failed initial eradication should consist of a different neutralizing action of these agents is short-lived, and combination of antibiotics to that used for initial frequent dosages are required. Magnesium containing treatment, administered for 10-14 days.

Ulcers frequently return when secondary endoscopy biopsy culture results.A proton antacids are discontinued. Studies have shown that a pump inhibitor is currently the standard treatment, and protein in the stomach called histamine stimulates part of triple therapy. Thereafter, symptomatic gastric acid secretion. Histamine antagonists (H2 patients, those with complicated peptic ulcer disease blockers) are drugs designed to block the action of (presenting with bleeding, stricture or perforation) and histamine on gastric cells, hence reducing acid output. those patients who require NSAIDs may still require Examples of H2 blockers are cimetidine (Tagamet), long-term proton pump inhibitor therapy. Intermittent ranitidine (Zantac), nizatidine (Axid), and famotidine on-demand therapy is suitable for patients without (Pepcid). While H2 blockers are effective in ulcer complications for the control of symptoms.Peptic ulcer healing, they have limited role in eradicating H. pylori surgery is now extremely rare for failed medical without antibiotics. Therefore, ulcers frequently return therapy due to the powerful acid suppression by proton when H2 blockers are stopped. Generally, these drugs pump inhibitors.

Side effects are uncommon; they treatment involves a proton-pump inhibitor include headache, diarrhea, constipation, nausea and medication, such as omeprazole (Prilosec), and two rash. Interestingly, proton-pump inhibitors do not have antibiotics, which may include clarithromycin, any effect on a person's ability to digest and absorb amoxicillin, or metronidazole.
