This product is a calcium channel blocker, and its action is related to the inhibition of calcium ion influx during myocardial and vascular smooth muscle depolarization. This product can effectively dilate the epicardial and subendocardial coronary arteries, relieve spontaneous angina pectoris or angina pectoris caused by coronary artery spasm induced by ergonovine; by slowing down the heart rate and lowering blood pressure, it reduces myocardial oxygen demand, increases exercise tolerance and relieves exertional angina pectoris. This product can relax vascular smooth muscle, reduce peripheral vascular resistance, and lower blood pressure; the extent of its blood pressure reduction is related to the degree of hypertension, and only slightly reduces blood pressure in people with normal blood pressure. This product has a negative inotropic effect and can slow down the conduction of the sinoatrial node and atrioventricular node.

This product is a phenothiazine antipsychotic, and its mechanism of action is mainly related to its blocking of dopamine receptors (DA2) in the mesolimbic system and mesocortical pathways. It has a blocking effect on dopamine (DA1) receptors, 5-hydroxytryptamine receptors, M-type acetylcholine receptors, and α-adrenaline receptors, and has a wide range of effects. In addition, this product can inhibit the dopamine receptors in the medulla oblongata emetic chemoreceptor area at low doses, and directly inhibit the vomiting center at high doses, producing a strong antiemetic effect. It inhibits the body temperature regulation center and lowers the body temperature. The body temperature can change with changes in the external environment. It blocks the action of peripheral α-adrenaline receptors, dilates blood vessels, causes a drop in blood pressure, and also has a certain effect on the endocrine system.

This product is a dibenzodiazepine antipsychotic. It has a strong blocking effect on the 5-hydroxytryptamine (5-HT2A) receptor and dopamine (DA1) receptor in the brain, and also has a blocking effect on the dopamine (DA4) receptor, and a weaker blocking effect on the dopamine (DA2) receptor. In addition, it also has anticholinergic (M1), antihistamine (H1) and anti-α-adrenaline receptor effects. Extrapyramidal reactions are rare, and generally do not cause an increase in blood prolactin. It can directly inhibit the ascending activation system of the brainstem reticular formation and has a strong sedative and hypnotic effect.

This product is a dried yeast body, rich in B vitamins, and has an auxiliary therapeutic effect on indigestion.

It has a strong antibacterial effect on most anaerobic bacteria, and the antibacterial spectrum includes Bacteroides fragilis and other Bacteroides, Fusobacterium, Clostridium perfringens, Eubacterium, Veillonella, Peptococcus and Peptostreptococcus. The bactericidal concentration is slightly higher than the inhibitory concentration. In addition, it also has a strong killing effect on amoeba and Trichomonas. The bactericidal mechanism is that nitro is reduced to a cytotoxin, which acts on the DNA metabolism process of bacteria and promotes cell death. The mechanism against amoeba is to inhibit its redox reaction, causing the nitrogen chain of the protozoa to break.
