Structure
Ranitidine Chemical Structure – C13H22N4O3S
Mode of action
The histamine H2 receptors located in the gastric parietal cells are competitively and irreversibly inhibited by ranitidine. As a result, there is a reduction in hydrogen ion concentration, gastrointestinal volume, and gastric acid secretion.
Uses
Used to treat and prevent stomach ulcers as well as indigestion, heartburn, acid reflux, and gastro-oesophageal reflux disease.
