Ranitidine: Mechanism of Action and Therapeutic Effects

Ranitidine is a medication used to treat diseases related to stomach acid and belongs to the class of H2 receptor antagonists. The main functions and benefits of ranitidine are as follows: 1. Inhibits gastric acid secretion: Ranitidine reduces gastric acid secretion by inhibiting H2 receptors in the stomach lining cells. It effectively relieves symptoms such as stomach pain and heartburn caused by excessive stomach acid. 2. Treats gastric ulcers: This medication has a positive effect on the treatment of gastric and duodenal ulcers, promotes ulcer healing, and reduces the risk of recurrence. 3. Relieves gastroesophageal reflux disease (GERD): Ranitidine decreases the frequency of stomach acid flowing back into the esophagus, alleviating the burning and discomfort caused by GERD. When using ranitidine, it should be noted that long-term or high-dose use may cause side effects such as headache, dizziness, or gastrointestinal discomfort. Patients with impaired liver or kidney function should use it cautiously, and dosage adjustment may be necessary. Pregnant and breastfeeding women should consult a doctor before use.
