Difluprednate is a corticosteroid, a derivative of prednisolone obtained by fluorination at the 6- and 9-positions, followed by esterification of the 17 and 21-hydroxyl groups with butyric acid and acetic acid, respectively (see figure). Accordingly, difluprednate is sometimes abbreviated DFBA, for difluoroprednisolone butyrate acetate.


On June 24, 2008, the US Food and Drug Administration (FDA) approved difluprednate for the treatment of post-operative ocular inflammation and pain.[1] It is marketed by Sirion Therapeutics under the tradename Durezol.

Clinical Trials

Difluprednate ophthalmic emulsion 0.05% is also being studied in other ocular inflammatory diseases, including a U.S. Phase 3 study evaluating difluprednate for the treatment of anterior uveitis.[2]
