This product belongs to the benzamide antipsychotic drug. Its characteristic action is to selectively block the dopamine (DA2) receptors of the mesolimbic system, with little effect on other neurotransmitter receptors, mild anticholinergic effect, and no obvious sedative and anti-excitement and agitation effects. This product also has strong antiemetic and gastric juice secretion inhibitory effects.

Tetracycline antibiotics are broad-spectrum antibacterial agents with bactericidal effects at high concentrations. They inhibit peptide chain growth and bacterial protein synthesis by binding to the A position of the bacterial ribosome 30S subunit. They are sensitive to many Rickettsia, Mycoplasma, Chlamydia, atypical mycobacteria, spirochetes, etc. They are more effective against Gram-positive bacteria than Gram-negative bacteria, but Enterococci are resistant to them.

By inhibiting the production of very low-density lipoprotein and triglyceride and increasing their catabolism at the same time, it reduces blood low-density lipoprotein, cholesterol and triglyceride; it also increases the production of apolipoprotein A1 and A11, thereby increasing high-density lipoprotein. This product also has the effect of reducing blood uric acid in normal people and patients with hyperuricemia. Animal experiments have shown that fenofibrate is teratogenic and carcinogenic.

Calcium ion antagonists exert their pharmacological effects by regulating the influx of calcium ions on the cell membranes of myocardial conduction cells, myocardial contractile cells, and arterial smooth muscle cells; they dilate the main coronary arteries and arterioles in normal and ischemic parts of the heart, antagonize spontaneous or ergonovine-induced coronary artery spasm, increase myocardial oxygen delivery in patients with coronary artery spasm, relieve and prevent coronary artery spasm; they reduce total peripheral resistance and myocardial oxygen consumption; they reduce the influx of calcium ions, prolong the effective refractory period of the atrioventricular node, and slow down conduction.
