Ocular drug delivery: a clue from nanotechnology

Ocular drug delivery: a clue from nanotechnology

Topical administration is the most common route of ocular drug delivery. Despite its apparent easy accessibility, the eye is well protected from foreign materials and drugs by a number of very efficient mechanisms such as blinking, induced lacrimation, tear turnover, nasolacrimal drainage, which cause rapid removal of substances from the eye surface and by the cornea, which forms the physical-b...

Nanotechnology Approaches for Ocular Drug Delivery

Blindness is a major health concern worldwide that has a powerful impact on afflicted individuals and their families, and is associated with enormous socio-economical consequences. The Middle East is heavily impacted by blindness, and the problem there is augmented by an increasing incidence of diabetes in the population. An appropriate drug/gene delivery system that can sustain and deliver the...

Nanotechnology: a New Approach for Ocular Drug Delivery System

In current drug delivery scenario, despite numerous scientific efforts, efficient ocular drug delivery remains a challenge for pharmaceutical scientists. In ocular drug delivery system, ocular infections are treated by various topical drug applications in the form of solutions, suspensions and ointment. These conventional dosage forms suffer from the problems of poor ocular bioavailability due ...
