What is tobramycin-ophthalmic ointment, and how does it work (mechanism of action)?

Tobramycin is an aminoglycoside antibiotic that interferes with bacterial production of proteins, ultimately leading to bacterial death. Tobramycin, like other aminoglycoside antibiotics, targets various gram-positive and gram-negative bacteria. Targeted organisms include Staphylococcus aureus, Staphylococcus epidermidis, Streptococci, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes, Proteus mirabilis, Morganella morganii, Proteus vulgaris (most strains), Haemophilus influenzae, Haemophilus aegyptius, Moraxella lacunata, Acinetobacter calcoaceticus, and some Neisseria species. The FDA approved tobramycin ophthalmic solution in December 1980.
