The main pharmacological action is to relax vascular smooth muscle. Nitroglycerin releases nitric oxide (NO), which is the same as endothelial relaxing factor, activating guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP) in smooth muscle and other tissues, leading to dephosphorylation of myosin light chain, regulating the contractile state of smooth muscle, and causing vasodilation.

This product belongs to the lincomycin antibiotics, which is a derivative of lincomycin. Its antibacterial spectrum is the same as that of lincomycin, and its antibacterial activity is 4 to 8 times stronger than that of lincomycin. It has high antibacterial activity against Gram-positive bacteria such as Staphylococcus (including penicillin-resistant strains), Streptococcus, Corynebacterium diphtheriae, Bacillus anthracis, etc. It also has good antibacterial activity against Gram-negative anaerobic bacteria. Most of the Bacteroides, including Bacteroides fragilis, Fusobacterium, Peptococcus, Peptostreptococcus, and Clostridium perfringens, are highly sensitive to this product. Gram-negative aerobic bacteria, including Haemophilus influenzae, Neisseria, and Mycoplasma, are resistant to this product. There is no cross-resistance between this product and penicillin, chloramphenicol, cephalosporins and tetracyclines, but it has partial cross-resistance with macrolides and complete cross-resistance with lincomycin. The mechanism of action of this product is to bind to the 50S subunit of the bacterial ribosome, prevent the elongation of the peptide chain, and thus inhibit the protein synthesis of bacterial cells. This product is an antibacterial drug, but at high concentrations, it also has a bactericidal effect on certain bacteria.

Anti-platelet aggregation and disaggregation, dilation of arterioles, improvement of microcirculation, improvement of cerebral blood flow and blood circulation and stasis-removing effects

One of the eight essential amino acids for the human body, it combines with ATP to generate S-adenosine, promotes methylation of liver cell membrane phospholipids, reduces intrahepatic bile stasis, strengthens transsulfurization, restores normal physiological functions of liver cells, promotes the disappearance of jaundice and recovery of liver function, promotes choline synthesis by supplying methyl groups, promotes liver fat metabolism, protects the liver and has detoxification effects.

It combines with pyrophosphate in the body to form a cocarboxylase, participating in the oxidative decarboxylation reaction of pyruvate and α-ketoglutarate in glucose metabolism, and is necessary for glucose metabolism.

Adrenal cortex hormone drugs. They have multiple pharmacological effects such as anti-inflammatory, anti-allergic and immunosuppressive. 1 Anti-inflammatory effect: Glucocorticoids reduce and prevent tissue response to inflammation, thereby reducing the manifestation of inflammation. 2 Immunosuppressive effect: prevent or inhibit cell-mediated immune response, delayed allergic reaction, and reduce the expansion of primary immune response. 3 Anti-toxic and anti-shock effect: Glucocorticoids can counteract the stimulation of bacterial endotoxins on the body, reduce cell damage, and play a role in protecting the body.
