Omez-DSR Capsule 15s are part of a class of drugs known as gastrointestinal agents that are used to treat conditions like Zollinger-Ellison syndrome, GERD, peptic ulcers, epigastric discomfort, heartburn, and indigestion. When stomach acid rushes back into the food pipe often, it causes gastroesophageal reflux disease (GERD) (oesophagus). Peptic ulcers are lesions that form on the stomach and intestines' inner linings. Overproduction of acid is a symptom of the Zollinger-Ellison syndrome, which is characterised by the growth of tumours in the upper small intestine. Omeprazole, a proton pump inhibitor, and Domperidone are combined as Omez-DSR Capsule 15s (a dopamine antagonist). The mechanism of action of omeprazole is the inhibition of the gastric proton pump, an enzyme that produces acid in the stomach. Disclaimer:For more information contact your physician.
