May 01, 2010 · Ocular drug delivery has been a major challenge to pharmacologists and drug delivery scientists due to its unique anatomy and physiology. Static barriers (different layers of cornea, sclera, and retina including blood aqueous and blood–retinal barriers), dynamic barriers (choroidal and conjunctival blood flow, lymphatic clearance, and tear dilution), and efflux pumps in conjunction pose a ...Author: Ripal Gaudana, Hari Krishna Ananthula, Ashwin Parenky, Ashim K.

The highly branched structure of dendrimers allows incorporation of wide range of drugs, hydrophobic as well as hydrophilic. In ocular drug delivery, few promising results were reported with these branched polymeric systems [4,92,93]. Poly (amidoamine) (PAMAM) dendrimers are …Author: Ashaben Patel, Kishore Cholkar, Vibhuti Agrahari, Ashim K Mitra

However, increasing the viscosity of the delivery solution only produces a modest gain in ocular drug absorption, particularly for lipid-soluble drugs. The residence time for many drugs is especially reduced by their pH, tonicity and the direct effect of certain drugs on lacrimation, which all affect the residence time of drugs in the lower fornix.

Sep 17, 2012 · ocular drug delivery systems 1. INTRODUCTION Ocular administration of drug isprimarily associated with the need totreat ophthalmic diseases. Eye is the most easily accessible site fortopical administration of a medication. Ideal ophthalmic drug delivery mustbe able to sustain the drug release andto remain in the vicinity of front of theeye for prolong period of time.

delivery. Drug delivery to eye has always been a daunting task in the field of pharmaceutical research due to unique anatomy and physiology of the eye. One of the major problems encountered by conventional ocular dosage forms include rapid precorneal drug loss due to nasolacrimal drainage, tear turnover and drug dilution resulting in
