Abstract: Background and Purpose: Empagliflozin (EMP) is a sodium-glucose cotransporter 2 (SGLT2) inhibitor used for the management of type 2 diabetes mellitus. The danger of glaucoma in type 2 diabetes mellitus patients is known to be reduced using SGLT2 inhibitors. Empagliflozin is also believed to reduce the level of inflammatory markers. The present work has been undertaken for monitoring intraocular pressure and anti-inflammatory activity using the empagliflozin ocular film formulation. The effect of colloidal silicon dioxide upon the dynamics of swelling and drug release performance was also studied. Experimental Approach: Hydroxypropyl methylcellulose-based ocular film of empagliflozin was prepared, including silicon dioxide in different ratios as 1:0.00, 1:0.01, 1:0.02, 1:0.04, and 1:0.06 (namely, EMA0, EMA1, EMA2, EMA3 and EMA4, respectively) using casting and solvent evaporation. Swelling and drug release studies of the films were conducted in phosphate buffer solution (pH 7.4), and the kinetic mechanisms of swelling and drug release were evaluated. Intraocular pressure was measured after application of the film in the normotensive rabbit eye. Moreover, the anti-inflammatory effect was assessed using a rabbit ocular carrageenan-induced inflammation model. Key Results: Swelling behaviour followed Fickian mechanism in the order: EMA3<EMA2<EMA0<EMA4
