ACTION: Gentamicin sulfate, a broad spectrum antibiotic, is a highly effective topical treatment in primary and secondary bacterial infections of the eye and surrounding tissues. Gentamicin is bactericidal in vitro against a wide variety of gram-positive and gram-negative bacteria. Concentrations of gentamicin sulfate required to inhibit growth of gram-positive and gram-negative clinical and laboratory strains of bacteria tested were less than those of neomycin in most instances.1,2 Gentamicin is active against most gram-negative bacteria including Pseudomonas aeruginosa, indole positive and negative Proteus species, Escherichia coli, Klebsiella sp. and Enterobacter sp. Gentamicin is also active against strains of gram-positive bacteria including Staphylococcus species and Streptococcus species.
