Contents
Pariet tablets 5 mg are an acid secretion suppressant. They potently reduce gastric acid secretion and mitigate its harmful effects. As a result, they promote healing of gastric ulcers and gastroesophageal reflux disease (GERD) and relieve stomach pain and heartburn. They are also effective for gastric ulcers caused by aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs).
 
In addition, they are used as part of eradication therapy for Helicobacter pylori, the bacterium responsible for various gastric lesions including gastritis and peptic ulcers. In this use, Pariet is combined with two other antibiotics; reducing gastric acid enhances the efficacy of the antibiotics and increases eradication success rates.
 
Efficacy
It suppresses gastric acid secretion by inhibiting the acid-secreting mechanism of gastric mucosal cells. As a result, it promotes rapid healing of gastric and duodenal ulcers and relieves pain and heartburn associated with gastroesophageal reflux disease. It is commonly used to treat gastric ulcers, duodenal ulcers, and GERD, and as an adjunct in Helicobacter pylori eradication therapy. It is also used to prevent recurrence of gastric or duodenal ulcers during low‑dose aspirin therapy.
