Azithromycin is a 15-membered macrolide antibiotic. In vitro tests have shown that it has antibacterial effects on a variety of common pathogens, including Gram-positive aerobic bacteria (such as Staphylococcus aureus, Streptococcus pyogenes, etc.), Gram-negative aerobic bacteria (such as Haemophilus influenzae, Moraxella catarrhalis, etc.), anaerobic bacteria (such as Bacteroides fragilis, etc.), sexually transmitted disease microorganisms (such as Treponema pallidum, Neisseria gonorrhoeae, etc.) and other microorganisms (such as Borrelia tenuissima, Mycoplasma pneumoniae, etc.). The mechanism of action is the same as that of erythromycin, mainly binding to the 50S subunit of the bacterial ribosome to inhibit 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 pathogens in clinical practice, 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, which mainly binds to the 50S subunit of the bacterial ribosome and inhibits RNA-dependent protein synthesis.

The mechanism of action is the same as that of erythromycin, mainly binding to the 50S subunit of the bacterial ribosome to inhibit RNA-dependent protein synthesis.

It achieves antibacterial effect by inhibiting the activity of bacterial DNA gyrase and hindering the replication of bacterial DNA. It has the characteristics of broad antibacterial spectrum and strong antibacterial effect, and has good antibacterial effect on most Enterobacteriaceae, Gram-negative bacteria, some Gram-positive bacteria, Legionella, Mycoplasma, Chlamydia, but has poor effect on anaerobic bacteria and enterococci.
