Minisec (omeprazole) 20 mg is a proton pump inhibitor (PPI) used to reduce stomach acid production, offering relief from conditions such as gastroesophageal reflux disease (GERD), stomach ulcers, and erosive esophagitis. Omeprazole works by inhibiting acid production in the stomach, providing effective relief from heartburn and promoting the healing of the stomach and esophagus lining. Minisec is commonly prescribed for short-term management of acid-related conditions and is well-suited for individuals needing quick relief from acid discomfort.
