Specification
Tobramycin is also known as tobramycin or nepaxin. One of the aminoglycoside antibiotics. Usually sulfate. The antibacterial spectrum is similar to that of gentamicin, but the antibacterial activity against Pseudomonas aeruginosa (PseudChemicalbookomonasaeruginosa) is 2 to 4 times stronger, and it is also effective against gentamicin-resistant strains; it is also effective against other G-bacteria. The antibacterial activity is slightly inferior to that of gentamicin. Can be used to treat a variety of serious infections caused by Pseudomonas aeruginosa and other G-bacteria.
