Oskar DSR 30 mg/20 mg Capsule is a combination pharmaceutical formulation containing Domperidone 30 mg and Omeprazole 20 mg, indicated for the treatment of gastroesophageal reflux disease (GERD), peptic ulcers, and related acid-peptic disorders. Domperidone, a peripheral dopamine D2 receptor antagonist, enhances gastrointestinal motility and accelerates gastric emptying, thereby alleviating symptoms such as nausea, vomiting, and bloating. Omeprazole, a proton pump inhibitor (PPI), suppresses gastric acid secretion by irreversibly inhibiting the H+/K+ ATPase enzyme system in the gastric parietal cells, promoting ulcer healing and symptom relief. The synergistic action of these two agents provides effective management of acid reflux and dyspeptic symptoms by reducing gastric acidity and improving gastric motility. Oskar DSR is typically administered orally once daily before meals, with dosage adjustments based on clinical response and patient tolerance. It is contraindicated in patients with known hypersensitivity to either component, and caution is advised in individuals with hepatic impairment or prolonged QT interval. Adverse effects may include headache, dry mouth, abdominal cramps, and, rarely, extrapyramidal symptoms. This combination therapy offers a comprehensive approach to managing acid-related gastrointestinal disorders, improving patient compliance through a single-dose regimen.
