What does it do?

Ranitidine hydrochloride is a drug from the class of histamine H2 receptor antagonists that regulates gastric acid secretion. It is mainly used to treat gastrointestinal diseases such as peptic ulcers. It helps reduce mucosal damage caused by excessive gastric acid.

Ranitidine hydrochloride works by binding to the histamine H2 receptors in the gastric wall cells to inhibit gastric acid secretion. This reduction in gastric acid creates a favorable environment for the recovery of the mucosa at the ulcer site. It also helps alleviate pain and inflammation caused by excessive gastric acid.

Good to know

Unlike other gastric acid suppressants such as proton pump inhibitors, ranitidine hydrochloride directly blocks histamine receptors. As a result, its mechanism of action and side effect profile are different, and the gastric acid suppression effect appears relatively quickly. However, its use has been restricted recently due to some safety concerns.
