Omzer-D Capsule contains a combination of Domperidone 10mg and Omeprazole 20mg, formulated to manage gastrointestinal disorders characterized by acid reflux, heartburn, and delayed gastric emptying. Domperidone is a peripheral dopamine D2 receptor antagonist that enhances gastrointestinal motility by increasing the movement of the stomach and intestines, thereby facilitating gastric emptying and reducing symptoms such as nausea and vomiting. Omeprazole, a proton pump inhibitor, suppresses gastric acid secretion by irreversibly inhibiting the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells, leading to prolonged reduction of gastric acid production. The combined action of these agents provides symptomatic relief in conditions such as gastroesophageal reflux disease (GERD), dyspepsia, and peptic ulcer disease. Omzer-D Capsule is indicated for patients requiring both acid suppression and improved gastric motility. It should be used under medical supervision, with caution advised in patients with known hypersensitivity to either component, liver impairment, or prolactin-related disorders. Common side effects may include headache, dry mouth, abdominal cramps, or dizziness. Omzer-D Capsule is contraindicated in patients with gastrointestinal hemorrhage, obstruction, or perforation. Proper adherence to prescribed dosage and duration is essential to optimize therapeutic outcomes and minimize adverse effects.
