How SiSu® Works

The SiSu® platform consists of a blend of proprietary, hydrophobic biodegradable polymers, and proprietary blends of regulatorily accepted solvents. These materials are matched to drug characteristics, target tissue, and release requirements to produce the final formulated product. Upon introduction of the formulation into an aqueous environment within the eye, e.g. the vitreous, the SiSu® platform forms a semi-solid depot of polymer-bound drug. As the aqueous environment interacts with the depot, the polymer is slowly dissolved, releasing the drug into the eye.
