As a histamine H1 receptor antagonist, this product can counteract the capillary dilation caused by allergic reactions, reduce the permeability of capillaries, and relieve wheezing caused by bronchial smooth muscle contraction. This product has a long-lasting antihistamine effect and also has a significant central inhibitory effect, which can increase the effects of anesthetics, analgesics, hypnotics and local anesthetics. This product is mainly metabolized in the liver.

Dopamine 2 (D2) receptor antagonist, 5-hydroxytryptamine 4 (5-HT4) receptor agonist, has a mild inhibitory effect on 5-HT3 receptors. It acts on dopamine receptors in the medullary chemo-emetic zone (CTZ) to increase the threshold of CTZ, and has a strong central antiemetic effect; it blocks hypothalamic dopamine receptors, inhibits prolactin inhibitory factor, promotes prolactin secretion, and has a certain lactation effect; it has a slight inhibitory effect on other parts of the central nervous system, has a weak sedative effect, and rarely causes hypnotic effects; it promotes the movement of the stomach and upper intestinal segments, increases the tension of the gastrointestinal sphincter in the resting state, increases the tension and contraction amplitude of the lower esophageal sphincter, and increases the pressure at the lower end of the esophagus.

Participates in bone formation and reconstruction of bone tissue after fracture, as well as muscle contraction, nerve transmission, coagulation mechanism and reduces capillary permeability, etc.
