It can counteract the capillary dilation caused by allergic reactions, reduce capillary permeability, have a mild bronchial smooth muscle spasmolysis effect, and also has a significant central nervous system sedative effect and a certain antitussive effect.

A strong expectorant that increases the secretion of respiratory glands, dilutes sputum, and makes it easier to cough up.

Salt expectorants can reflexively increase the secretion of respiratory mucosal glands, making sputum easier to cough up and facilitating the removal of sticky sputum.

A broad-spectrum antibacterial drug, also effective against Chlamydia trachomatis. Mainly used to treat bacterial external eye infections, trachoma and bacterial intraocular infections.

It has special effects on Staphylococcus (Staphylococcus aureus, Staphylococcus epidermidis and penicillin-resistant strains), Streptococcus (Group A hemolytic streptococci, non-hemolytic streptococci and Streptococcus pneumoniae), Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis (indole-negative) and indole-positive Proteus, Haemophilus influenzae and Haemophilus conjunctivitis, Moraxella conjunctivitis, Acinetobacter calcoaceticus (Herellea vaginacola), and Neisseria. Gentomycin-resistant strains are still sensitive to tobramycin. No strains resistant to tobramycin have been found so far, but long-term use may lead to bacterial resistance.

This product belongs to the aminoglycoside antibiotics, and its antibacterial spectrum is similar to that of gentamicin. It has antibacterial effects on a variety of Gram-negative bacteria. Its antibacterial effect on Pseudomonas aeruginosa is 3 to 5 times stronger than that of gentamicin. Its mechanism of action is to bind to the 30S subunit of the bacterial ribosome and inhibit the synthesis of bacterial proteins.
