This product belongs to the macrolide antibiotics. It has antibacterial activity against Staphylococcus (except methicillin-resistant strains), all groups of streptococci and Gram-positive bacilli. Neisseria, Haemophilus influenzae, Bordetella pertussis, etc. are also sensitive to this product. This product also has antibacterial effects on various anaerobic bacteria except Bacteroides fragilis and Fusobacterium. It also has inhibitory effects on Legionella, Campylobacter fetus, certain spirochetes, Mycoplasma pneumoniae, Rickettsia and Chlamydia. This product is an antibacterial agent, but it also has a bactericidal effect on certain bacteria at high concentrations. It can penetrate the bacterial cell membrane and reversibly bind to the 50S subunit of the bacterial ribosome near the donor site ("P" site), blocking the transfer RNA (t-RNA) from binding to the "P" site, and also blocking the self-acceptor site ("A" site) of the polypeptide chain.

Tetracycline antibiotics. This product is a broad-spectrum antibacterial agent. Many Rickettsia, Mycoplasma, Chlamydia, and Spirochete are sensitive to this product. Enterococci are resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, Yersinia, etc. are also sensitive to this product. Due to the widespread use of oxytetracycline and tetracyclines over the years, common clinical pathogens have serious resistance to oxytetracycline, including Gram-positive bacteria such as Staphylococcus and most Gram-negative bacteria. There is cross-resistance between this product and different varieties of tetracycline antibiotics. The mechanism of action of this product is that the drug can specifically bind to the A position of the 30S subunit of the bacterial ribosome, inhibit the growth of the peptide chain and affect the synthesis of bacterial proteins.
