Eflone Usage And Synthesis

Chemical Properties

Off-White to Pale Yellow Solid

Uses

Fluorometholone Acetate is a glucocorticoid; anti-inflammatory.

Definition

ChEBI: A steroid ester resulting from the formal condensation of the 17-hydroxy function of fluorometholone with acetic acid. Used in the treatment of steroid responsive inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the eye.

brand name

Flarex (Alcon).

in vivo

Hourly topical administration of 0.1% Fluorometholone acetate ophthalmic suspension produced, on the average, a 47% reduction in the polymorphonuclear leukocytes invading the cornea during an experimentally induced inflammatory keratitis in New Zealand albino rabbits (1.5-2.0 kg). Fluorometholone acetate (0.1%) formulated as a high-viscosity carbomer gel and applied at three-hour intervals reduced invading leukocytes in the cornea an average of 48%, an effect not significantly different from hourly administration of the suspension[1].
