Trade Names:FML-S- Ophthalmic Suspension 0.1% fluorometholone and 10% sodium sulfacetamide

Pharmacology

Fluorometholone

Depresses formation, release, and activity of endogenous mediators of inflammation as well as modifying body's immune response.

Sulfacetamide

Competitively antagonizes PABA, an essential component of folic acid synthesis.

Indications and Usage

Treatment of 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. Use of corticosteroids in combination with an anti-infective agent 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.
