Ocular Drug Delivery: An Overview

Abstract

The eye is a well protected organ. It has been regarded as a challenging undertaking to develop an effective treatment for ocular illnesses, particularly those affecting the posterior segment. Scientists have been challenged to identify other modes of administration, such as periocular channels, due to the limitations of the usual route of administration. Due of its potential to get around several difficulties with existing therapy, targeted medication delivery has attracted a lot of attention in the field. The use of nanotechnology in the treatment of a variety of ailments has shown great promise. Several innovative ocular drug delivery technologies, including microemulsions, nanosuspensions, nanoparticles, liposomes, nano-some, dendrimers, implants, and hydrogels, have been briefly discussed in this review. There is potential in the innovative medicine delivery technologies that are currently gaining traction.
