Gentamicin sulfate More Info

Gentamicin sulfate is an aminoglycoside antibiotic primarily used to treat various bacterial infections. It is effective against a wide range of gram-negative bacteria and some gram-positive bacteria, making it a valuable option in clinical settings, particularly for serious infections.

Mechanism of Action

Gentamicin acts by binding to the 30S ribosomal subunit of bacteria, inhibiting protein synthesis. Its mechanism involves:
Disruption of Translation: By binding to the ribosomal RNA at helix 44 of the 16S rRNA, gentamicin alters the normal function of the ribosome, leading to the misreading of mRNA. This results in the incorporation of incorrect amino acids into proteins, producing non-functional proteins that can lead to bacterial cell death.
Bactericidal Effect: The accumulation of mistranslated proteins and the disruption of protein synthesis ultimately cause cell lysis and death, making gentamicin bactericidal rather than merely bacteriostatic.

Applications

Gentamicin is indicated for the treatment of:
Serious Infections: Such as sepsis, pneumonia, and urinary tract infections caused by susceptible organisms.
Bone Infections: Including osteomyelitis.
Endocarditis: Often in combination with other antibiotics.
Intra-abdominal Infections: Particularly in cases where gram-negative bacteria are suspected.

Routes of Administration

Gentamicin can be administered through various routes:
Intravenous (IV): Commonly used for serious infections requiring immediate action.
Intramuscular (IM): An alternative route when IV access is not available.
Topical: Available as ointments or solutions for localized infections.
