Qinghai Lukang Dadi Pharmaceutical Co., Ltd.

It has a broad-spectrum antimicrobial effect in vitro, including aerobic Gram-negative and Gram-positive bacteria, anaerobes, Rickettsia, spirochetes and Chlamydia. It has a bactericidal effect on Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis; it only has an antibacterial effect on anaerobic bacteria such as Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Group B hemolytic Streptococcus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhi, Salmonella paratyphi, Shigella, Bacteroides fragilis, etc. Pseudomonas aeruginosa, Acinetobacter, Enterobacter, Serratia marcescens, indole-positive Proteus, methicillin-resistant Staphylococcus and Enterococcus are usually resistant to chloramphenicol. Chloramphenicol is fat-soluble, enters bacterial cells by diffusion, and reversibly binds to the 50S subunit of bacterial ribosomes, inhibiting the formation of peptide chains, thereby preventing protein synthesis.

Dilate the coronary arteries, femoral arteries, and cerebral arteries, increase cerebral blood flow, strengthen blood circulation in the limbs, reduce blood viscosity, weaken vascular resistance, reduce myocardial oxygen consumption, improve cardiac function, enhance microcirculation, increase peripheral blood flow, change blood rheology, lower blood pressure, and improve heart rhythm

It has high antibacterial activity against common aerobic Gram-positive bacteria, such as Staphylococcus aureus (including those resistant to penicillin G), Staphylococcus epidermidis, beta-hemolytic Streptococcus, viridans Streptococcus and Streptococcus pneumoniae. It has good antibacterial effect on anaerobic bacteria, including Clostridium diphtheriae, and Clostridium perfringens. It has no activity against Gram-negative bacteria such as enterococci, meningococci, Neisseria gonorrhoeae, and Haemophilus influenzae, as well as fungi. There is no cross-resistance with penicillin, chloramphenicol, cephalosporins and tetracyclines, and there is partial cross-resistance with macrolides. It acts on the 50S subunit of the ribosome of sensitive bacteria, preventing the extension of the peptide chain, thereby inhibiting the protein synthesis of bacterial cells. It is generally an antibacterial agent, but at high concentrations, it also has a bactericidal effect on certain bacteria.

It is a multi-component macrolide antibiotic produced by Streptomyces. Its antibacterial properties are similar to those of erythromycin. It has strong antibacterial effects on Gram-positive bacteria and mycoplasmas, and also has antibacterial effects on some Gram-negative bacteria such as Neisseria meningitidis and Neisseria gonorrhoeae. Some erythromycin-resistant Staphylococcus aureus may still be sensitive to this product. It works by acting on the 50S subunit of the bacterial ribosome, hindering the synthesis of bacterial proteins, and is an antibacterial drug during the growth period.
