ABSTRACT: Most peptic ulcers can be healed with proper treatment. 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.
