May 01, 2010 · Ocular drug delivery has been a major challenge to pharmacologists and drug delivery scientists due to its unique anatomy and physiology. Static barriers (different layers of cornea, sclera, and retina including blood aqueous and blood–retinal barriers), dynamic barriers (choroidal and conjunctival blood flow, lymphatic clearance, and tear dilution), and efflux pumps in conjunction pose a ...Author: Ripal Gaudana, Hari Krishna Ananthula, Ashwin Parenky, Ashim K.

ocular drug delivery systems are as follows: The ocular bioavailability must be increased from less than 1% to 15-20% of the administered dose. Most of the currently marketed ocular drugs were initially developed for non-ocular applications, hence their low or nonspecificity. So, there is a need to develop new drug candidates primarily
