Lansoprazole is a medication used to treat certain stomach and esophagus problems, such as acid reflux, gastroesophageal reflux disease (GERD), and ulcers. It works by decreasing the amount of acid your stomach makes. Lansoprazole is a proton pump inhibitor (PPI). This type of medicine helps reduce the amount of acid made by the stomach. It is available as a prescription and over-the-counter (OTC) medicine.
Lansoprazole is a medication classified as a proton pump inhibitor (PPI) [1]. It works by reducing the amount of acid produced by the stomach. Here's a breakdown of its uses and mechanism of action:
What is Lansoprazole used for?
Lansoprazole is used to treat and prevent various stomach and esophagus conditions caused by excess acid production. Here are some common applications:
- Gastroesophageal Reflux Disease (GERD): This condition occurs when stomach acid backs up into the esophagus, causing heartburn and irritation [1, 2]. Lansoprazole helps heal existing damage in the esophagus and prevent further acid reflux.
- Peptic ulcers: These are sores that develop in the lining of the stomach or duodenum (the first part of the small intestine) due to stomach acid and digestive juices [2]. Lansoprazole promotes healing of ulcers and reduces the risk of recurrence.
- Erosive esophagitis: This is inflammation of the esophagus caused by prolonged exposure to stomach acid [2]. Lansoprazole helps heal the inflamed esophagus.
- Zollinger-Ellison syndrome: This is a rare condition where a tumor in the pancreas or small intestine produces excessive amounts of gastrin, a hormone that stimulates acid production in the stomach [2]. Lansoprazole helps control acid secretion in these patients.
- H. pylori infection: Lansoprazole can be used in combination with antibiotics to treat stomach ulcers caused by Helicobacter pylori (H. pylori) bacteria [2]. H. pylori can disrupt the stomach lining and increase acid production.
How does Lansoprazole work?
Lansoprazole works by targeting proton pumps within the stomach cells. These pumps are responsible for producing stomach acid. By inhibiting the pumps, Lansoprazole significantly reduces the amount of acid released into the stomach [1]. This provides relief from symptoms like heartburn, indigestion, and stomach discomfort.
