Cisapride (CAS 81098-60-4) is a high-purity prokinetic agent API with a targeted gastrointestinal regulatory mechanism. It enhances the release of acetylcholine in the myenteric plexus, stimulating the contraction of gastrointestinal smooth muscles to accelerate gastric emptying, improve esophageal peristalsis and promote intestinal transit. It is mainly used for the research of functional dyspepsia, gastroesophageal reflux disease and other gastrointestinal motility disorders. Its refined crystalline form ensures consistent bioactivity and low impurity profiles, making it a reliable active ingredient for gastroenterology pharmaceutical R&D.
