Used primarily in the treatment of gastric and duodenal ulcers, lafutidine helps reduce stomach acid secretion and protects the gastric mucosa. It is effective in managing symptoms of acid-related disorders such as heartburn and acid reflux. Due to its dual action—blocking histamine H2 receptors and enhancing mucosal defense—it supports ulcer healing and prevents recurrence. Commonly prescribed for conditions like gastritis and gastroesophageal reflux disease (GERD), it offers faster symptom relief compared to some traditional H2 blockers.
