This product is a dopamine 2 (D2) receptor antagonist, and also has a 5-hydroxytryptamine 4 (5-HT4) receptor agonist effect, and has a mild inhibitory effect on 5-HT3 receptors. It can act on dopamine receptors in the medullary emetic chemoreceptor zone (CTZ) to increase the threshold of CTZ, and has a strong central antiemetic effect. This product can also block hypothalamic dopamine receptors, inhibit prolactin inhibitory factor, and promote the secretion of prolactin, so it has a certain lactation effect. The inhibitory effect on other parts of the central nervous system is relatively small, with a weak sedative effect and less hypnotic effect. The effect on the gastrointestinal tract is mainly in the upper digestive tract, promoting the movement of the stomach and upper intestinal segments; increasing the tension of the gastrointestinal sphincter in the resting state, increasing the tension and contraction amplitude of the lower esophageal sphincter, and increasing the pressure at the lower end of the esophagus.

It has astringent, gastric mucosal protective and antibacterial effects. Because this product is insoluble in water, it forms a protective film on the gastric mucosal wound surface after oral administration, reducing the irritation of food to the gastric mucosa; in the intestine, bismuth combines with hydrogen sulfide to form insoluble bismuth sulfide (Bi2S3) on the intestinal mucosa, slowing down intestinal peristalsis; at the same time, bismuth salts also have antibacterial effects.

It has anti-inflammatory, antipyretic and analgesic effects. Its mechanism of action is to reduce the synthesis of prostaglandins by inhibiting cyclooxygenase. It stops the formation of pain nerve impulses in inflammatory tissues and inhibits inflammatory reactions, including inhibiting the chemotaxis of leukocytes and the release of lysosomal enzymes. As for the antipyretic effect, it acts on the hypothalamic temperature regulation center, causing peripheral vasodilation and sweating, which increases heat dissipation. This central antipyretic effect may also be related to the inhibition of prostaglandin synthesis in the hypothalamus.
