H2 antagonists block histamine-induced gastric acid secretion from the parietal cells of the gastric mucosa (lining of the stomach). H2 antagonists are used to treat gastroesophageal reflux …

Aug 11, 2024 · H2 receptor blockers, or H2 receptor antagonists (H2RAs), are gastric acid-suppressing agents frequently used in various gastric conditions. The FDA approves these drugs to treat uncomplicated gastroesophageal reflux disease (GERD), gastric or duodenal ulcers, gastric hypersecretion, and mild to infrequent heartburn or indigestion.

H2 antagonists, sometimes referred to as H2RAs[1] and also called H2 blockers, are a class of medications that block the action of histamine at the histamine H 2 receptors of the parietal cells in the stomach. This decreases the production of stomach acid.

Mar 18, 2024 · H2 blockers are medications that suppress stomach acid production. They’re a short-term treatment for stomach ulcers, duodenal ulcers and acid reflux. You can get them over the counter or by prescription. Brands include Tagamet®, Pepcid® and Axid®. What are H2 blockers (H2 antagonists)?

Dec 8, 2024 · H2 receptor blockers are drugs that are used to treat gastroesophageal reflux disease (GERD) and peptic ulcers. This drug is effective, cheap, and safe for relieving heartburn.

Jan 25, 2018 · The selective histamine type 2 receptor antagonists/blockers (H2 blockers) are widely used in the treatment of acid-peptic disease, including duodenal and gastric ulcers, gastroesophageal reflux disease and common heartburn.

Apr 13, 2022 · H2 antagonists suppress stomach acid and are used to treat or prevent a variety of stomach conditions, such as GERD and ulcers. H2 antagonists are also known as H2 receptor antagonists (H2RAs) or H2 blockers. They are available in brand name and generic formulations, and as prescription and over-the-counter (OTC) drugs.

Histamine H2 receptor antagonists (H2RAs) or H2-blockers are a class of stomach acid-suppressing agents and are used to treat gastroesophageal reflux and duodenal ulcers. H2RAs suppress the release of stomach acid to treat conditions caused by excess acid secretion.

Possible drug interactions with histamine (H2)-receptor antagonists (H2RAs) include: Azole antifungals — because of decreased gastric acidity, the absorption of ketoconazole or itraconazole may be reduced if taken with an H 2 RA. Protease inhibitors — atazanavir plasma levels are reduced by H 2 RAs.

May 4, 2024 · Here is a table of the most commonly used H2 antagonists. Histamine-2 antagonists block the release of hydrochloric acid in response to gastrin. These drugs include cimetidine (Tagamet), ranitidine (Zantac), famotidine (Pepcid), and nizatidine (Axid). The desired actions of H2 antagonists include the following:
