Used primarily to reduce stomach acid production, this compound is widely prescribed for treating gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. It helps heal esophageal damage caused by acid reflux and provides relief from heartburn symptoms. Often taken orally, it is effective in both short-term and long-term management of acid-related conditions. It is also used in combination with antibiotics to eradicate Helicobacter pylori, a bacterium linked to gastric ulcers. Its action lasts for up to 24 hours, making once-daily dosing sufficient for most patients.
