What is tobramycin and dexamethasone? How does it work (mechanism of action)?
TOBRADEX® ST (tobramycin / dexamethasone ophthalmic suspension 0.3%/0.05%) ophthalmic suspension is indicated for steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where superficial bacterial ocular infection or a risk of bacterial ocular infection exists.
Ocular steroids are indicated in inflammatory conditions of the palpebral and bulbar conjunctiva, cornea and anterior segment of the globe where the inherent risk of steroid use in certain infective conjunctivitides is accepted to obtain a diminution in edema and inflammation. They are also indicated in chronic anterior uveitis and corneal injury from chemical, radiation or thermal burns, or penetration of foreign bodies.
The use of a combination drug with an anti-infective component is indicated where the risk of superficial ocular infection is high or where there is an expectation that potentially dangerous numbers of bacteria will be present in the eye.
The particular anti-infective drug in this product is active against the following common bacterial eye pathogens: Staphylococci, including S. aureus and S. epidermidis (coagulase-positive and coagulase-negative), including penicillin-resistant isolates. Streptococci, including some Group A and other beta-hemolytic species, some nonhemolytic species, and some Streptococcus pneumoniae. Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes, Proteus mirabilis, Morganella morganii , most Proteus vulgaris isolates, Haemophilus influenzae , H. aegyptius, Moraxella lacunata, Acinetobacter calcoaceticus and some Neisseria species.

The recommended dose is one or two drops (solution or ointment) or one drop (suspension) into the conjunctival sac every four to six hours. The dosing interval may be reduced to every two hours during the initial 24 to 48 hours. The hands should be washed before each use of Tobradex or any eye medication. The head is tilted back, and the lower eye lid is pulled down with the index finger to form a pouch. The tip of the dropper should not touch the eye or eyelid. The bottle of Tobradex should be squeezed slightly to allow the prescribed number of drops (generally one or two drops) into the pouch. If the ointment is being used, a small strip (about 1cm or 1/2 inch) of ointment should be squeezed into the pouch. The eye should then be closed gently for one to two minutes without blinking.
