This product is a macrolide antibiotic. Its mechanism of action is similar to that of erythromycin, and its antibacterial spectrum is also similar to that of erythromycin, but its antibacterial activity against most Gram-positive bacteria is slightly worse. Some erythromycin-resistant Staphylococcus aureus are still sensitive to kitasamycin. This product also has considerable activity against diphtheria, tetani, Neisseria gonorrhoeae, pertussis, Rickettsia and Chlamydia trachomatis.

This product is a neutral compound of aspirin and acetaminophen bonded by an ester bond. It has antipyretic and analgesic effects, with fewer adverse reactions than aspirin, and is easily tolerated by patients.

This product is an aminoglycoside antibiotic that has good antibacterial effects on various Gram-negative and Gram-positive bacteria. Its mechanism of action is to bind to the 30S subunit of bacterial ribosomes and inhibit the synthesis of bacterial proteins. In recent years, the number of Gram-negative bacteria resistant to gentamicin has increased significantly.
