It has high antibacterial activity against common aerobic Gram-positive bacteria, such as Staphylococcus aureus (including those resistant to penicillin G), Staphylococcus epidermidis, β-hemolytic Streptococcus, viridans Streptococcus and Streptococcus pneumoniae. It has good antibacterial effect on anaerobic bacteria, including Clostridium diphtheriae, and Clostridium perfringens. It has no activity against Gram-negative bacteria such as enterococci, meningococci, Neisseria gonorrhoeae, and Haemophilus influenzae, as well as fungi. There is no cross-resistance with penicillin, chloramphenicol, cephalosporins and tetracyclines, and there is partial cross-resistance with macrolides. It acts on the 50S subunit of the ribosome of sensitive bacteria, preventing the extension of the peptide chain, thereby inhibiting the protein synthesis of bacterial cells. It is generally an antibacterial agent, but at high concentrations, it also has a bactericidal effect on certain bacteria.

Aminoglycoside antibiotics have good antibacterial effects on various Gram-negative and Gram-positive bacteria, and inhibit bacterial protein synthesis by binding to the bacterial ribosome 30S subunit.

Aminoglycoside antibiotics have good antibacterial effects on various Gram-negative and Gram-positive bacteria. Their 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.
