Metoclopramide binds to dopamine 2 (D2) receptors in the peripheral nervous system (PNS), antagonizing dopamine-mediated relaxation of gastrointestinal smooth muscle and promoting gastroprokinesis; the pyloric sphincter and the duodenal bulb are relaxed, peristalsis of the duodenum and jejunum increase, and gastric emptying and intestinal transit accelerate.
