It works by inhibiting DNA gyrase and DNA replication in bacterial prokaryotes. Due to its unique mechanism of action, it has the characteristics of a broad antibacterial spectrum and strong antibacterial activity, and has a strong antibacterial effect on both Gram-positive and Gram-negative bacteria. It is effective against infections such as Staphylococcus, Streptococcus pyogenes, Streptococcus hemolyticus, Enterococcus, Pneumococcus, Escherichia coli, Citrobacter, Klebsiella pneumoniae, Enterobacter, Serratia, Proteus, Pseudomonas aeruginosa, Haemophilus influenzae, Acinetobacter, CamPylobacter, PeptostoreptoCoCus, and Chlamydia sensitive strains. There is no cross-resistance between this product and other antibacterial drugs.

It has a significant effect on increasing the number of peripheral blood leukocytes in normal rabbits. The peak of the leukocyte count occurs on the 4th day after the first administration, which is 72% higher than before the administration, which is better than the leukocyte-raising drug shark liver alcohol. It has a significant effect on increasing leukocytes in rabbits induced by cobalt 60-gamma rays and deep X-ray irradiation. It also has a preventive effect on leukopenia when administered two days before irradiation. It can also prevent leukopenia in mice caused by mitomycin C. It has a synergistic inhibitory effect on solid Ehrlich carcinoma when used in combination with cyclophosphamide, and the toxicity of leukopenia caused by cyclophosphamide is significantly reduced.

This product belongs to the macrolide antibiotics, which is the ethyl succinate of erythromycin. It is more stable than erythromycin in gastric acid. It has antibacterial activity against Staphylococcus (except methicillin-resistant strains), various 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, some spirochetes, Mycoplasma pneumoniae, Rickettsia and Chlamydia. This product is an antibacterial agent, but it also has a bactericidal effect on some bacteria at high concentrations. This product can penetrate the bacterial cell membrane and form a reversible bond with 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 displacement of the polypeptide chain from the acceptor site (A site) to the P site, thereby inhibiting bacterial protein synthesis.

This product is a broad-spectrum antibiotic, the mechanism of action is to inhibit bacterial protein synthesis, and is effective against most Gram-negative and some Gram-positive bacteria, as well as Chlamydia trachomatis and Rickettsia.

This product is a bisphosphonate bone resorption inhibitor, which may mainly inhibit the dissolution and formation of hydroxyapatite by binding to the bone, thereby producing an anti-bone resorption effect. Its mechanism of action may also be related to the direct change of the morphology of osteoclasts or the direct inhibition of cytokines mediated by osteoblasts.
