Esolyst-D Capsule SR is a combination medication containing Domperidone 30mg and Esomeprazole 40mg, formulated to provide sustained relief from gastrointestinal disorders. Domperidone, a peripheral dopamine D2 receptor antagonist, enhances gastrointestinal motility and accelerates gastric emptying, thereby alleviating symptoms such as nausea, vomiting, bloating, and discomfort associated with delayed gastric emptying. Esomeprazole, a proton pump inhibitor, suppresses gastric acid secretion by irreversibly inhibiting the H+/K+ ATPase enzyme system in the gastric parietal cells, effectively reducing acid-related damage and promoting mucosal healing. This synergistic combination is indicated for the management of gastroesophageal reflux disease (GERD), erosive esophagitis, peptic ulcers, and functional dyspepsia, particularly when accompanied by motility disturbances. Esolyst-D Capsule SR is designed for sustained release, ensuring prolonged therapeutic plasma concentrations and improved patient compliance. It should be administered as prescribed, typically before meals, and is contraindicated in patients with known hypersensitivity to its components, prolactinoma, or gastrointestinal hemorrhage. Caution is advised in patients with hepatic impairment or cardiac arrhythmias. Common adverse effects may include headache, dry mouth, and abdominal discomfort. Consultation with a healthcare professional is recommended prior to initiation to optimize treatment outcomes and monitor for potential drug interactions.
