Azithromycin is a 15-membered macrolide antibiotic. In vitro tests have shown that azithromycin has antibacterial effects on a variety of common clinical pathogens, including Gram-positive aerobic bacteria, Gram-negative aerobic bacteria, anaerobic bacteria, sexually transmitted disease microorganisms and other microorganisms. The mechanism of action is the same as that of erythromycin, mainly binding to the 50S subunit of the bacterial ribosome and inhibiting RNA-dependent protein synthesis.

Azithromycin is a 15-membered macrolide antibiotic. In vitro tests have shown that azithromycin has antibacterial effects on a variety of common clinical pathogens, including: Gram-positive aerobic bacteria, Staphylococcus aureus, Streptococcus pyogenes (Group A b-hemolytic streptococci), Pneumococcus, a-hemolytic streptococci (grass-green streptococci) and other streptococci, diphtheria (rod-shaped) bacilli. This product shows cross-resistance to erythromycin-resistant Gram-positive bacteria, including fecal streptococci (enterococci) and methicillin-resistant Staphylococcus aureus strains. Gram-negative aerobic bacteria: Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis, Acinetobacter, Yersinia, Legionella pneumophila, Bordetella pertussis, Bordetella parapertussis, Shigella, Pasteurella, Vibrio cholerae, Parahaemolyticus, Shigella-like Pyrimonas. The activity of this product against the following Gram-negative bacteria depends on the strain, and sensitivity testing is required: Escherichia coli, Salmonella typhi, Enterobacter, Hydrophila, Klebsiella. Anaerobic bacteria: Bacteroides fragilis, Bacteroides, Clostridium perfringens, Peptostreptococcus, Fusobacterium necroticum, Propionibacterium acnes. Sexually transmitted disease microorganisms: Treponema pallidum, Neisseria gonorrhoeae, Haemophilus dukei. Other microorganisms: including Borrelia tenens (Lyme disease body), Mycoplasma pneumoniae, Mycoplasma hominis, Ureaplasma urealyticum, Chlamydia trachomatis, Pneumocystis carinii, Mycobacterium avium, Campylobacter, Listeria monocytogenes. The following Gram-negative bacteria are usually resistant: Proteus, Serratia, Morganella, Pseudomonas. The mechanism of action is the same as erythromycin, mainly binding to the 50S subunit of the bacterial ribosome, inhibiting RNA-dependent protein synthesis.

It has a bactericidal effect by inhibiting the bacterial DNA gyrase and has antibacterial effects on Gram-negative bacteria (such as Escherichia coli, Klebsiella pneumoniae, etc.) and some Gram-positive bacteria (such as Staphylococcus aureus and hemolytic Streptococcus).
