Gentamicin is an aminoglycoside antibiotic primarily used for the treatment of serious Gram-negative bacterial infections. It acts by inhibiting bacterial protein synthesis. While its systemic use is approved and common, the ATC code S03AA06 refers to gentamicin for ophthalmic use in the treatment of eye infections such as conjunctivitis and blepharitis.
Pharmacokinetics
Pharmacokinetic parameters reported for adult patients, receiving intravenous administration for systemic infections. Ophthalmic absorption is minimal and systemic exposure is generally considered negligible; therefore, the PK model is based on IV data in adults.
