This product is a calcium channel blocker that can prevent cell damage caused by pathological intracellular calcium overload due to ischemia and other reasons; it has the effects of relieving vasospasm, vestibular inhibition, anti-epileptic effect, myocardial protection, improving renal function and anti-histamine effect.

This product is a glucocorticoid drug with strong local anti-inflammatory and anti-allergic effects

After oral administration, this product is broken down by trypsin in the intestine, slowly releasing tannic acid, which precipitates the protein in the surface layer of the intestinal mucosa, forming a protective film to reduce irritation, reduce inflammatory permeability and intestinal peristalsis, and play an astringent and antidiarrheal role.

It can increase the activity of microsomal enzymes in liver cells and accelerate the liver's detoxification ability; it can also reduce the increase in serum glutamic-alanine aminotransferase in rats caused by carbon tetrachloride; it can also stabilize cell membranes of various types of liver damage caused by liver poisons such as carbon tetrachloride, phalloidin, thioacetamide, and crotalin, thereby achieving a significant liver protection effect.

It is a histamine H2 receptor antagonist, competitively binds to histamine H2 receptors, reversibly inhibits receptor function, blocks gastric acid formation and reduces basal gastric acid, significantly inhibits nocturnal gastric acid secretion and gastric acid secretion stimulated by food, caffeine, aminopyrazole and pentagastrin. Oral administration of 300 mg can significantly inhibit gastric acid secretion at night (about 12 hours), with an inhibition rate of 90%, and has no effect on pepsin activity.
