Rabeprazole is a proton pump inhibitor that suppresses gastric acid production in the stomach. It has several medical uses: the management of conditions that involve excess gastric acid production (e.g. ZollingerEllison syndrome), conditions that are worsened by gastric acid (e.g. ulcerations of the gastrointestinal tract), and conditions involving prolonged exposure to gastric acid (e.g. symptomatic gastroesophageal reflux disease). Levosulpiride belongs to the class of antipsychotic medicines. However, it is primarily used for its gut motility properties i.e to improve food movement and treats disorders of the stomach and intestines.
