Fluorometholone Acetate is the acetate salt form of fluorometholone, a synthetic glucocorticoid with anti-inflammatory and anti-allergic properties. Fluorometholone acetate exerts its effect by interacting with cytoplasmic glucocorticoid receptors and subsequently activates glucocorticoid receptor mediated gene expression. The synthesis of certain anti-inflammatory proteins is induced while the synthesis of certain inflammatory mediators is inhibited. As a result, there is an overall reduction in chronic inflammation and autoimmune reactions.
