What is gentamicin-injection, and how does it work (mechanism of action)?

Gentamicin is a broad spectrum aminoglycoside antibiotic that is most effective against aerobic gram-negative rods. Gentamicin is also used in combination with other antibiotics to treat infections caused by gram positive organisms such as Staphylococcus aureus and certain species of streptococci. Additionally, gentamicin is used in combination with a penicillin antibiotic to treat endocarditis (infection of the heart). Gentamicin kills bacteria (bactericidal) by inhibiting the synthesis of bacterial proteins. Gentamicin irreversibly binds to the 30S ribosomal subunits. This binding interferes with the formation of messenger RNA (mRNA) and the subsequent formation of nonfunctional proteins and the eventual death of susceptible bacteria. Gentamicin was approved by the US Food and Drug Administration (FDA) in 1966.
