Pantoprazole 40 mg is a proton pump inhibitor (PPI) used to reduce the amount of acid produced in the stomach. Here's a quick rundown of its common uses: 🔹 Primary Uses of Pantoprazole 40 mg Gastroesophageal Reflux Disease (GERD): Treats symptoms like heartburn, acid regurgitation, and inflammation of the esophagus. Erosive Esophagitis: Helps heal damage to the esophagus caused by stomach acid. Zollinger-Ellison Syndrome: Manages excess acid production due to tumors in the pancreas or duodenum. Stomach Ulcers or Duodenal Ulcers: Often used in combination with antibiotics to treat ulcers caused by H. pylori infection. NSAID-induced Ulcer Prevention: Protects the stomach lining for those on long-term nonsteroidal anti-inflammatory drugs (like ibuprofen). 💊 How It Works Pantoprazole blocks the H+/K+ ATPase enzyme system (the proton pump) in the stomach lining, which is the final step of acid production. By inhibiting this, it significantly reduces gastric acid secretion.
