Fluorometholone acetate, also known as oxylone acetate and sold under the brand names Flarex, Florate, and Omnitrol, is a synthetic glucocorticoid corticosteroid and a corticosteroid ester, as well as a progestogen and progestogen ester.^{[1][2][3][4]: 186} It is the C17α acetate ester of fluorometholone.^[1][2][3]

In addition to its potent corticosteroid activity, fluorometholone acetate is a progestogen.^[4] It has been studied in the treatment of breast cancer in women and has been found to be effective, producing remission in about 20% of women with advanced breast cancer at an oral dosage of 50 mg/day.^[4] However, it also produces severe Cushing's syndrome-like symptoms like plethora, moon face, glycosuria, marked weight gain, hypertension, and osteoporosis at this dosage due to its glucocorticoid activity.^[4]
