There are many pro-gastrointestinal dynamics drugs, commonly used 5-hydroxytryptamine receptor agonists, M cholinergic receptor agonists, dopamine receptor antagonists and so on. 1.5-Hydroxytryptamine agonist: It can play a role in increasing the tension of the lower esophageal sphincter, increasing the ability of gastric contraction and gastroduodenal coordination. Commonly, there are cisapride, tegaserod and so on. Commonly used in the treatment of decreased gastric motility, reflux esophagitis and so on. 2.M choline receptor agonists: mainly through the enhancement of gastrointestinal dynamics, but can not make the stomach and duodenum coordinated movement, at the same time can increase the secretion of gastric juice and other digestive juices. Common drugs include carbamylcholine. 3. Dopamine receptor antagonist: can increase the lower esophageal sphincter tone, increase gastric contractility. Common drugs include domperidone. The use of specific drugs should be under the guidance of a doctor.
