Therapeutic indications:

For steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where bacterial infection or a risk of bacterial infection exists. Ocular corticosteroids are indicated in inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe where the inherent risk of corticosteroids 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 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: Staphylococcus aureus, Escherichia coli, Haemophilus influenzae, Klebsiella/Entero

CLINICAL PHARMACOLOGY
Corticosteroids suppress the inflammatory response to a variety of
agents and they
probably delay or slow healing. Since corticosteroids may inhibit the
body’s defense
mechanism against infection, a concomitant antimicrobial drug may be
used when this
inhibition is considered to be clinically significant in a particular
case.
When a decision to administer both a corticosteroid and an
antimicrobial is made, the
administration of such drugs in combination has the advantage of
greater patient
compliance and convenience, with the added assurance that the
appropriate dosage of
both drugs is administered, plus assured compatibility of ingredients
when both types of
drugs are in the same formulation and, particularly, that the correct
volume of drug is
delivered and retained.
