| Description | Fluorometholone acetate is a synthetic glucocorticoid corticosteroid and a corticosteroid ester. Fluorometholone acetate potently inhibits carbonic anhydrase (CA) with IC50s of 2.18 μM and 17.5 μM for hCA-I and hCA-II, respectively. Fluorometholone acetate has anti-inflammatory effect and has the potential for external ocular inflammation research[1][2][3]. |

| Target | IC50: 2.18 μM (human carbonic anhydrase (hCA)-I) and 17.5 μM (hCA-II)[2] Ki: 1.044 μM (hCA-I) and 9.98 μM (hCA-II)[2] |

| In Vitro | For Fluorometholone acetate, a Ki value from Lineweaver-Burk plots is obtained as 1.044 μM (noncompetitive) for hCA-I and 9.98 μM (non-competitive) for hCA-II[2]. |

| 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]. |
