Anti-angina drug. This product belongs to the nitrate compound, which has the effect of preventing the free calcium ions in cells, increasing the permeability of cell membranes to potassium ions, dilating coronary blood vessels, continuously increasing coronary blood flow, and inhibiting coronary artery spasm. When dilating coronary blood vessels, it does not affect blood pressure, heart rate, myocardial contractility, and myocardial oxygen consumption. This product also has the effect of inhibiting platelet aggregation and preventing thrombosis.

It is a derivative of vitamin B6, which can promote the metabolism of glucose and amino acids in the brain and improve systemic assimilation. It increases carotid blood flow, improves cerebral blood flow, and strengthens brain function. It is suitable for improving symptoms such as headache, dizziness, insomnia, memory loss, lack of concentration, and mood changes caused by concussion syndrome, sequelae of brain trauma, encephalitis, and sequelae of meningitis; it is also used for cerebral arteriosclerosis, senile dementia, etc.

The structure is similar to that of papaverine. Single or continuous administration can increase blood flow to the brain, heart, kidneys and limbs. It can directly relax vascular smooth muscle to dilate blood vessels, and has a selective and sustained dilation effect on the brain, kidneys, blood vessels and coronary arteries, thereby increasing blood flow. The effect is weaker and more lasting than that of papaverine. This product can also promote collateral circulation. It has almost no effect on respiration, heart rate, cardiac output, myocardial oxygen consumption, blood pressure, etc.

This product has a broad-spectrum antimicrobial effect in vitro, including aerobic Gram-negative and Gram-positive bacteria, anaerobes, Rickettsia, spirochetes and Chlamydia. It has bactericidal effects on the following bacteria: Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis. It only has antibacterial effects on the following bacteria: Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Group B hemolytic Streptococcus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhi, Salmonella paratyphi, Shigella, Bacteroides fragilis and other anaerobic bacteria. The following bacteria are usually resistant to chloramphenicol: Pseudomonas aeruginosa, Acinetobacter, Enterobacter, Serratia marcescens, indole-positive Proteus, methicillin-resistant Staphylococcus and Enterococcus. This product is an antibacterial agent. Chloramphenicol is fat-soluble and enters bacterial cells by diffusion, and reversibly binds to the 50S subunit of the bacterial ribosome, which blocks the growth of the peptide chain (possibly due to the inhibition of the action of transpeptidase), thereby inhibiting the formation of the peptide chain and preventing protein synthesis.

It can improve the blood supply to the vertebral artery, regulate the function of the vestibular system, inhibit the vomiting center, and have anti-vertigo and antiemetic effects.
