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.

Aug 11, 2024 · H2 receptor blockers, or histamine-2 receptor antagonists (H2RAs), are gastric acid-suppressing agents frequently used to treat various gastric conditions.

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)?

Jan 25, 2018 · These medications are extremely well tolerated and are used by a high proportion of the general population to treat peptic ulcer disease, heartburn, esophagitis, and miscellaneous minor upper gastrointestinal symptoms.

Oct 1, 2003 · In patients with reflux esophagitis, treatment is directed at acid suppression through the use of lifestyle modifications (e.g., elevating the head of the bed, modifying the size and composition of...

Proton pump inhibitors (PPIs) and H2 Receptor Antagonists (H2RAs) are indicated in the management of numerous gastrointestinal conditions including gastroesophageal reflux disease (GERD), duodenal ulcer, gastric ulcer, Helicobacter pylori infection, and to reduce the risk of non-steroidal anti-inflammatory drugs (NSAID)-associated gastric ulcers.

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.

Histamine 2 -receptor antagonists (H 2 RAs) slow gastric acid production by competitively and reversibly binding to one of the pathways for stimulation of acid production, the H 2 receptors on parietal cells [9, 10].

Histamine H2 receptor antagonists (H2RAs) competitively inhibit H2 receptors, resulting in a significant reduction in gastric acid secretion.

Histamine H2 receptor antagonists (H2RAs) were widely used to inhibit gastric acid secretion, but its association with adverse events remains controversial and unclear.
