Medipan D 10 mg/40 mg Capsule is a combination of two medicines: Domperidone and Pantoprazole. Domperidone is a prokinetic which works on the upper digestive tract to increase the movement of the stomach and intestines, allowing the food to move more easily through the stomach. Pantoprazole is a proton pump inhibitor (PPI) which works by reducing the amount of acid in the stomach which helps in the relief of acid-related indigestion and heartburn.
