Selectively inhibits succinate dehydrogenase in the muscles of the worm, affects the anaerobic metabolism of the muscles of the worm, and reduces energy production. It causes neuromuscular depolarization, and the muscles undergo continuous contraction and paralysis; the drug's mimetic cholinergic effect is conducive to the excretion of the worm. It may have an inhibitory effect on the microtubule structure of the worm. It also has immune regulation and immune preparation functions.

Nifedipine is a dihydropyridine calcium antagonist that selectively inhibits the transmembrane transport of calcium ions into myocardial cells and smooth muscle cells, and inhibits the release of calcium ions from cells without changing the plasma calcium ion concentration. 1) It can simultaneously dilate the coronary arteries in the normal blood supply area and the ischemic area, antagonize spontaneous or ergonovine-induced coronary artery spasm, increase the delivery of myocardial oxygen to patients with coronary artery spasm, and relieve and prevent coronary artery spasm. 2) It can inhibit myocardial contraction, reduce myocardial metabolism, and reduce myocardial oxygen consumption. 3) It can dilate peripheral resistance vessels, reduce peripheral resistance, reduce systolic and diastolic blood pressure, and reduce cardiac afterload. 4) It can delay the sinoatrial node function and atrioventricular conduction of isolated hearts; electrophysiological studies of whole animals and humans have not found that this product has the effect of delaying atrioventricular conduction, prolonging the recovery time of the sinoatrial node, and slowing down the sinoatrial node rate.

It binds to H2 receptors and inhibits gastric acid secretion. It is a potent H2 receptor blocker, and its gastric acid inhibition effect is 5 to 12 times that of cimetidine on a molar basis.

It is involved in the formation of antibodies and collagen in the body, tissue repair (including certain redox reactions), the metabolism of phenylalanine, tyrosine, and folic acid, the utilization of iron and carbohydrates, the synthesis of fat and protein, as well as the maintenance of immune function, hydroxylation of serotonin, maintaining the integrity of blood vessels, and promoting the absorption of non-heme iron.

Vitamin B6 is an important component of coenzymes, involved in the normal metabolism of sugar, protein, and fat, and is related to the production of white blood cells and hemoglobin.
