Eprakast DSR Capsule is a combination medication that belongs to the proton pump inhibitors (PPIs) and dopamine antagonists category containing the active ingredients Esomeprazole and Domperidone. This drug treats conditions such as gastroesophageal reflux disease (in which the stomach acid and contents flow back into the esophagus), peptic ulcers (a sore or erosion that forms on the stomach lining), and nausea and vomiting. This medicine is contraindicated in people with a history of cardiac arrhythmias such as ventricular fibrillation, ventricular tachycardia, or QT prolongation or in those taking medications that prolong the QT interval. This tablet may cause side effects such as dizziness, drowsiness, or vision changes in some individuals. If these effects occur, avoiding activities requiring alertness, such as driving, cycling, or operating machinery, is important until you feel better. Long-term use of this medicine may result in low magnesium levels in the body (hypomagnesemia). Symptoms of low magnesium levels include fatigue, muscle spasms or weakness, irregular heartbeat, and seizures. If you develop any of these symptoms, notify your doctor immediately. It is necessary to discuss using Eprakast DSR Capsule with your physician if you are pregnant, suspecting pregnancy, or breastfeeding.
