Conventional Opthalamic Drug Delivery System: An Outlook
The most sensitive and complex organ in the human body is the eye, so special attention should be needed for the administration of pharmaceutical substances into the eye. It is one of the most difficult for researchers in the preparation of drug delivery to the eye. The anatomical characteristics and physiological properties of the eye should be considered in drug delivery. The properties of pharmaceutical dosage forms depend upon the anatomy and physiology of the eye. Drug delivery on to the outer part as well as in the inner part of the ocular structure for the therapy is a unique and challenging one. Physiochemical, microbiological, and pharmaceutical properties lead to absorption and elimination of active therapeutic agents into and out of the eye. Loss of precorneal more and fastly occurs due to drainage in the region of extraocular are some of the drawbacks in ocular drug delivery of conventional dosage forms. To overcome these problems, advancements in conventional dosage forms take place.
