Dexit 0.5 mg + 10 mg combines two active ingredients, Dexlansoprazole and Domperidone, to treat gastrointestinal conditions. Dexlansoprazole is a proton pump inhibitor (PPI) that reduces stomach acid production, providing relief from conditions like acid reflux and gastroesophageal reflux disease (GERD). Domperidone, a dopamine antagonist, helps promote gastric motility and reduces nausea and vomiting, improving overall digestive function.
