Patent Review on Nanotechnology in Ocular Drug Delivery

Author(s): Nandini Gupta, Shivangi Goel and Himanshu Gupta
Pages 37-46 (10)
Numerous scientific efforts have been made till date to provide an efficient ocular drug delivery system, but still it is challenging for pharmaceutical scientists.

Most of the ocular diseases are treated by topical drug application in the form of suspensions, solutions and ointments. But because of various anatomical and pathophysiological barriers prevailing in the eye, these conventional dosage forms suffer from the problem of poor ocular bioavailability. Nanotechnology emerges not only as a potential tool for ocular drug delivery but also as a solution to drug targeting and improved bioavailability including various solubility related problems,

This review provides an overview of various limitations associated with ocular drug delivery, summarizes recent findings and patents on various nanotechnology products in ocular drug delivery.
