Physicochemical characterization and drug release of thermosensitive hydrogels composed of a hyaluronic acid/pluronic f127 graft.
Pluronic F127 (PF127) is a copolymer which forms thermosensitive hydrogels. Hyaluronic acid (HA) was grafted to PF127 to form a new hydrogel matrix (HP) for delivery of cisplatin and carboplatin. The physicochemical properties and drug delivery of the graft were examined in this study. HP system (20% HP copolymer in water) exhibited a similar sol-gel transition temperature (28.3 degrees C) as P...
متن کاملThermosensitive Pluronic® hydrogel: prolonged injectable formulation for drug abuse
OBJECTIVE The main objective of this study was to investigate thermosensitive Pluronic F-127 (PF-127) hydrogel for the modified release of a potent alcohol and opioid antagonist, naltrexone (NTX) hydrochloride, in a subcutaneous injectable dosage form. METHODS The NTX hydrogels were prepared by the cold method, and the in vitro release profiles of various formulations were evaluated at 37°C u...
متن کاملPreparation and characterization of a novel starch-based interpolyelectrolyte complex as matrix for controlled drug release.
A novel cationized starch-based interpolyelectrolyte complex (IPEC) was formed using kappa-carrageenan as the counter polyion. Characterization of the product by turbidity measurements and elemental analyses indicated a 1:1 interaction of the repeating units. FT-IR spectra for the IPEC showed some differences in comparison with either IPEC constituents or physical mixture. The swelling of table...
متن کاملHuperzine A-phospholipid complex-loaded biodegradable thermosensitive polymer gel for controlled drug release.
The huperzine A-phospholipid complex loaded biodegradable thermosensitive PLGA-PEG-PLGA polymer gel was studied as injectable implant system for controlled release of huperzine-A (HA). First, HA molecules were successfully incorporated into the soybean phosphatidylcholine (SP) molecules to form the huperzine-A-soybean phosphatidylcholine complexes (HA-SPC), which was proved by FT-IR, DSC, XRD, ...
متن کاملPluronic as nano-carier for drug delivery systems
A common approach for building a drug delivery system is to incorporate the drug within the nanocarrier that results in increased solubility, metabolic stability, and improved circulation time. However, recent developments indicate that selection of polymer nanomaterials can implement more than only inert carrier functions by being biological response modifiers. One representative of such mater...
