Preparation and evaluation of PCL-PEG-PCL micelles as potential nanocarriers for ocular delivery of dexamethasone
Objective(s): Micelles have been studied as nanoparticulate drug delivery systems for improving the topical ocular delivery of hydrophobic drugs. The objective of this study was to develop and characterize dexamethasone-loaded polycaprolactone-polyethylene glycol-polycaprolactone (PCL-PEG-PCL) micelles to improve patient compliance and enhance the ocular bioavailability of poorly water-soluble ...

متن کاملDegradability, cytocompatibility, and osteogenesis of porous scaffolds of nanobredigite and PCL–PEG–PCL composite
Biocomposite scaffolds were fabricated by incorporation of nanobredigite (n-BD) into the polymer of poly(ε-caprolactone)-poly(ethyleneglycol)-poly(ε-caprolactone) (PCL-PEG-PCL). The results revealed that the addition of n-BD into PCL-PEG-PCL significantly improved water absorption, compressive strength, and degradability of the scaffolds of n-BD/PCL-PEG-PCL composite (n-BPC) compared with PCL-P...
متن کاملPreparation and Characterization of PCL-PEG-PCL Copolymeric Nanoparticles as Polymersomes for Delivery Hydrophilic Drugs
Background: A novel drug delivery system using poly (ε-caprolactone) - poly (ethylene glycol) -poly (ε-caprolactone) (PCL-PEG-PCL) was established in this study. Methods: Ceftriaxone (CTX) was encapsulated within PCL-PEG-PCL nanoparticles by a double emulsion technique (w/o/w), leading to creation of ceftriaxone-loaded PCL-PEG-PCL (CTX/PCL-PEG-PCL) polymersomes. The resulting polymersomes...
متن کاملPreparation and characterization of PCL-PEG-PCL polymersomes for delivery of clavulanic acid
The Clavulanic acid (CLV) is a suicide inhibitor of bacterial beta-lactamase enzymes from Streptomyces clavuligerus. In the present study, a reliable drug delivery system using poly (ε-caprolactone)-poly (ethylene glycol)-poly (ε-caprolactone) (PCL-PEG-PCL) was synthesized and the release profile of the CLV from the drug-loaded polymersomes was evaluated. In this study, CLV was encapsulated wit...
