An experimental platform for systemic drug delivery to the retina.
Degenerative retinopathies, including age-related macular degeneration, diabetic retinopathy, and hereditary retinal disorders--major causes of world blindness--are potentially treatable by using low-molecular weight neuroprotective, antiapoptotic, or antineovascular drugs. These agents are, however, not in current systemic use owing to, among other factors, their inability to passively diffuse...
متن کاملMicrodialysis and drug delivery to the eye.
The eye presents unique challenges in both the development of tools for elucidating drug disposition as well as for the development of modes of drug delivery for treatment of ocular diseases. In this paper, we present a discussion of the anatomical and physiological characteristics and limitations present in the eye for microdialysis sampling of endogenous substrates and xenobiotics. To date, o...
متن کاملreview of intravitreal implants for extended drug delivery to the posterior segment of the eye
intravitreal injection is the most common approach for drug delivery to the posterior segment in humans. however, following the injection, drugs are rapidly eliminated from the vitreous, with half-lives up to a few days. depending on the rate of clearance from the vitreous, large boluses and frequent administrations may be required to ensure therapeutic levels over an extended period of time. m...
متن کاملThermoresponsive hydrogels as a new ocular drug delivery platform to the posterior segment of the eye.
PURPOSE To characterize thermoresponsive hydrogels (liquids at room temperature, gels at body temperature) as a novel drug delivery platform to the posterior segment. METHODS Thermoresponsive hydrogels were synthesized using poly(N-isopropylacrylamide) (PNIPAAm), cross-linked with poly(ethylene glycol) diacrylate (PEG-DA). Proteins were then encapsulated into the hydrogels, including bovine s...
متن کاملIon-exchange, an Approach to Prepare an Oral Floating Drug Delivery System for Diclofenac
Using ion-exchange resins, a multiple-unit type of oral floating dosage system has been prepared to prolong gastric emptying time of dosage form. The system is composed of beads of drug-resin complex, which are loaded with bicarbonate ions and coated with a hydrophobic polymer. The system is so designed that when the beads reach the stomach, chloride ions are exchanged with bicarbonate and drug...
