Lansoprazole is used to treat acid-related throat problems (erosive esophagitis). It works by blocking acid production in the stomach. This medication is known as a proton pump inhibitor (PPI). Decreasing excess stomach acid can help relieve symptoms such as heartburn, difficulty swallowing, persistent cough, and trouble sleeping. It can also prevent serious acid damage to your digestive system (e.g., ulcers, cancer of the esophagus).
