Tobramycin

Indications

Tobramycin is a topical antibiotic used to treat external bacterial infections of the eye caused by bacteria that are susceptible to it. as an example,

• Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus spp. of group A beta-hemolytic and nonhemolytic species are Gram-positive bacteria.
• E.coli, Pseudomonas aeruginosa, Enterobacter aerogenes, Klebsiella spp., Proteus mirabilis, Proteus vulgaris, Haemophilus influenzae, Morganella morganii, Acinetobacter calcoaceticus, Providentia, Serratia, Salmonella spp., and certain Neisseria spp. Gram-negative bacteria: E.coli

Pharmacology

Tobramycin’s bactericidal action is taken up into susceptible bacterial cells via an active transport pathway, similar to other aminoglycosides. Tobramycin binds to the 30s and, to a lesser extent, the 50s subunits of the bacterial ribosome within the cell, blocking protein synthesis and causing transcription mistakes.The manner in which cell death is brought about is imperfectly understood, and other mechanisms may contribute, including effects on membrane permeability.

Dosage & Administration
