Tobramycin is an aminoglycoside antibiotic primarily used for the treatment of serious bacterial infections caused by Gram-negative organisms, including Pseudomonas aeruginosa. It is commonly used in hospital settings for infections such as bacteremia, respiratory tract infections, urinary tract infections, and is also used in inhalation form for cystic fibrosis. Tobramycin is an approved drug and remains in current clinical use.
