Indications

Tobramycin is a topical antibiotic indicated in the treatment of external bacterial infections of the eye caused by susceptible organisms. Such as,

Gram-positive bacteria: Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus spp. of group A beta-hemolytic and some nonhemolytic species.

Gram-negative bacteria: E.coli, Pseudomonas aeruginosa, Enterobacter aerogenes, Klebsiella spp., Proteusmirabillis, Proteus vulgaris, Haemophilus influenzae, Morganella morganii, Acinetobacter calcoaceticus, Providentia, Serratia, Salmonella spp and some strains of Neisseria.

Pharmacology

Like other aminoglycosides, the bactericidal activity of Tobramycin is taken up into sensitive bacterial cells by an active transport process. Within the cell Tobramycin bind to the 30s, and to some extent to the 50s subunits of the bacterial ribosome, inhibiting protein synthesis and generating errors in the transcription of the genetic code. The manner in which cell death is brought about is imperfectly understood, and other mechanisms may contribute, including effects on membrane permeability.

Precautions

Minor sensitivity may occur to topically applied aminoglycosides in some patients. If a sensitivity reaction occurs, discontinue use. Prolonged use may result in overgrowth of nonsusceptible organisms and fungi.
