Generic

Tobramycin

 

Indications

Tobramycin eye drops is indicated for thetreatment of external infections of the eye and its appendages such as bacterial conjunctivitis, keratitis, corneal ulcer caused by susceptible bacteria.

 

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. Cell death is poorly understood, and other mechanisms, such as changes in membrane permeability, may play a role.

 

Dosage & Administration

In mild to moderate infection, instill 1 drop 4-6 times daily into the conjunctival sac(s). In severe cases of infection, instill 1 drop hourly until improvement is obtained, then reduce the dose gradually. Duration of treatment is 5-15 days.
