- Addresses bleeding gastric or duodenal ulcers
- Reduces risk of gastric ulcers associated with NSAID usage
- Used in combination with amoxicillin to eradicate H. pylori infection
Mechanism of Action
- Inhibits hydrogen ion transport by binding to an enzyme on gastric parietal cells
- Action occurs in an acidic gastric environment, leading to decreased stomach acid production
Therapeutic Effects
