Gastronix-DSR Capsule is a combination medication containing Domperidone 10mg and Omeprazole 20mg, formulated to manage gastrointestinal disorders characterized by acid reflux, heartburn, and delayed gastric emptying. Domperidone, a peripheral dopamine D2 receptor antagonist, enhances gastrointestinal motility by increasing the tone of the lower esophageal sphincter and accelerating gastric emptying, thereby alleviating symptoms such as nausea, vomiting, and bloating. Omeprazole, a proton pump inhibitor, suppresses gastric acid secretion by irreversibly inhibiting the H+/K+ ATPase enzyme system in gastric parietal cells, providing effective relief from acid-related conditions including gastroesophageal reflux disease (GERD), erosive esophagitis, and peptic ulcers. The synergistic action of these two agents in Gastronix-DSR Capsule offers both symptomatic relief and promotes mucosal healing. It is indicated for patients experiencing gastroesophageal reflux with associated delayed gastric emptying or dyspepsia. The capsule should be taken orally, preferably before meals, as directed by a healthcare professional. Caution is advised in patients with cardiac arrhythmias, liver impairment, or those on medications that prolong the QT interval. Adverse effects may include dry mouth, headache, abdominal discomfort, and rarely, extrapyramidal symptoms. Regular monitoring and adherence to prescribed dosage enhance therapeutic outcomes and minimize risks.
