Restores the imbalance between the excitation and inhibition of the cerebral cortex, has central inhibitory effects such as sedation, hypnosis and analgesia; increases cerebral blood flow and relieves cerebral vasospasm

This product can restore the imbalance between the excitation and inhibition process of the cerebral cortex, and has central inhibition effects such as sedation, hypnosis and analgesia. This product also has the effect of increasing cerebral blood flow and relieving cerebral vasospasm.

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.

This product is a lipid-regulating drug of the clofibric acid derivative class. Its mechanism of action in lowering blood lipids is not yet fully understood. It may involve peripheral fat decomposition, reduce the liver's uptake of free fatty acids and reduce the formation of triglycerides in the liver, inhibit the synthesis of very low-density lipoprotein apolipoproteins and reduce the production of very low-density lipoproteins. This product reduces blood triglycerides and increases blood high-density lipoprotein concentrations. Although it can slightly reduce blood low-density lipoprotein cholesterol blood concentrations, it may increase low-density lipoprotein in type IV hyperlipoproteinemia. A 5-year placebo-controlled study showed that this product can reduce the occurrence of severe coronary heart disease sudden death and myocardial infarction. Long-term administration of 10 times the human dose to rats increased the incidence of liver malignancies and benign testicular tumors.

Dihydropyridine calcium antagonists selectively inhibit calcium ions from entering smooth muscle cells and myocardial cells across the membrane, and have a greater effect on smooth muscle than on myocardium. They reduce peripheral vascular resistance and thus blood pressure by dilating peripheral arteries. They have no obvious negative inotropic effect at therapeutic doses and do not affect plasma calcium concentration.
