Tobramycin is an antibiotic that belongs to the aminoglycoside class. It is primarily used to treat infections caused by certain bacteria, particularly in patients with compromised immune systems or those with cystic fibrosis. Tobramycin works by inhibiting bacterial protein synthesis, effectively stopping the growth of bacteria. This medication can be administered through injections, inhalation, or eye drops, depending on the type of infection being treated. Common side effects may include kidney toxicity and hearing loss, especially with prolonged use. Regular monitoring is essential to minimize these risks while ensuring effective treatment.
