Therapeutic indications:

For steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where bacterial 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 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/Enterobacter

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 infections, 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.
The relative potency of corticosteroids depends on the molecular
structure, concentration and release
from the vehicle.
