Mechanism of Action

Lansoprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the (H+, K+)-ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the parietal cell, lansoprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production. This effect is dose-related and leads to inhibition of both basal and stimulated gastric acid secretion irrespective of the stimulus. Lansoprazole does not exhibit anticholinergic or histamine type-2 antagonist activity.


PREVACID and PREVACID SoluTab are proton pump inhibitors (PPIs) indicated for the:
1. Treatment of active duodenal ulcer in adults.
2. Eradication of H. pylori to reduce the risk of duodenal ulcer recurrence in adults.
3. Maintenance of healed duodenal ulcers in adults.
4. Treatment of active benign gastric ulcer in adults.
5. Healing of non-steroidal anti-inflammatory drugs (NSAID)-associated gastric ulcer in adults.
6. Risk reduction of NSAID-associated gastric ulcer in adults.
7. Treatment of symptomatic gastroesophageal reflux disease (GERD) in adults and pediatric patients 1 year of age and older.
8. Treatment of erosive esophagitis (EE) in adults and pediatric patients 1 year of age and older.
9. Maintenance of healing of EE in adults.
10. Pathological hypersecretory conditions, including Zollinger-Ellison syndrome (ZES) in adults.
