Microneedles for Ocular Drug Delivery
Statement of Purpose: Targeted drug delivery into the eye is a challenging task because of a variety of barriers that prevent safe and effective delivery. Topical application to the eye is hindered by low residence time resulting in poor diffusion of drug into intraocular tissues. Intravitreal injection can deliver drugs to the retina effectively but is invasive and carries risk of infection. I...
متن کاملStudies on In situ Hydrogel: A Smart Way for Safe and Sustained Ocular Drug Delivery
The present work describes the formulation development of ophthalmic in situ gelling system using thermo-reversible gelling polymer, i.e. Pluronic F 127 (PF127). Because of high concentration (20 to 25%w/v) of this polymer required for in situ gelation causes irritation to the eye. So, to reduce this concentration, an attempt was made to combine the PF127 with other polymers like hydroxy propyl...
متن کاملStimuli-responsive Hydrogel for Drug Delivery
Introduction Hydrogels have been extensively investigated as drug delivery carriers in biomedical applications.The stimuli-responsive hydrogel is generally created when an ionic monomer is incorporated into the hydrogel network, in which the charged group is formed and called fixed charge since its mobility is much less than that of freely mobile ions within the interstitial fluid. In this stud...
متن کاملOcular Drug Delivery
Traditionally, medication is delivered to the eye by three main mechanisms: Topical ocular administration, systemic administration, and intraocular or periocular injection. Each of these methods has significant disadvantages. Topical ocular solutions or ointments have less than a 1% penetration, have rapid dilution and tear washout, and rely substantially on owner compliance to administer the m...
