Novel Ophthalmic Drug Delivery

Human eye is protected by a unique anatomy and physiology. Therefore, it minimizes the transport of medication by traditional dosage forms to the eye and the therapeutic concentrations of drugs might not be maintained for long duration of time. Development of ocular drug delivery systems helped to place the medication on the anterior segment of the eye, and treat ocular infections for a prolonged period. Various biodegradable or non-biodegradable polymer intravitreal implants, have been widely investigated for the treatment of chronic vitreoretinal diseases. In the treatment of chronic diseases, the dosing frequency can be reduced by developing ocular drug delivery systems which provide controlled release of medication.
