The aim of the present study was to develop an oil-free o/w microemulsion, Cremophor EL:ethanol-propylene glycol:saline, for diallyl trisulfide (DATS) for intravenous (i.v.) administration to modify the safety and pharmacokinetics of DATS. The ternary diagram was constructed to identify the regions of dilutable microemulsions, and the optimal composition of(More)
The aim of the present study was to develop an oil-free o/w microemulsion, composed of pluronic F68, propylene glycol and saline, which solubilized poorly soluble anesthetic drug propofol for intravenous administration. The ternary diagram was constructed to identify the regions of microemulsions, and the optimal composition of microemulsion was determined(More)
Novel mixed polymeric micelles formed from biocompatible polymers, poly(ethylene glycol)-poly(lactide) (mPEG-PLA) and polyoxyethylene-660-12-hydroxy stearate (Solutol HS15), were fabricated and used as a nanocarrier for solubilizing poorly soluble anesthetic drug propofol. The solubilization of propofol by the mixed micelles was more efficient than those(More)
Therapeutic peptides are highly potent and specific in their functions, but difficulties in their oral administration require parallel development of viable delivery systems to improve their oral bioavailability. The objective of this study was to explore the feasibility of water-in-oil (w/o) microemulsions for improving the absorption of intraduodenally(More)
A series of monomethoxy poly(ethylene glycol)-poly(lactide) (mPEG-PLA) diblock copolymers were designed according to polymer-drug compatibility and synthesized, and mPEG-PLA micelle was fabricated and used as a nanocarrier for solubilization and oral delivery of Cyclosporine A (CyA). CyA was efficiently encapsulated into the micelles with nanoscaled(More)
The purpose of this work was to prepare and characterize a novel ethosomal carrier for tacrolimus, an immunosuppressant treating atopic dermatitis (AD), and to investigate inhibition action upon allergic reactions of mice aiming at improving pharmacological effect for tacrolimus in that commercial tacrolimus ointment (Protopic®) with poor penetration(More)
To improve the oral bioavailability of poorly water-soluble cyclosporin A (CyA), polymeric micelles based on monomethoxy poly(ethylene glycol)-b-poly(d,l-lactic acid) (mPEG-PLA) were prepared. In vitro release test showed that the cumulative release percentage, about 85%, of CyA from polymeric micelles within 24 h was comparable to that from Sandimmun(More)
The purpose of this study was to evaluate the feasibility of in situ thermosensitive hydrogel based on chitosan in combination with disodium α-d-Glucose 1-phosphate (DGP) for ocular drug delivery system. Aqueous solution of chitosan/DGP underwent sol-gel transition as temperature increased which was flowing sol at room temperature and then turned into(More)
The main objective of the present work was to prepare and assess dermal delivery of tacrolimus-loaded ethosomes versus classic liposomes. Both delivery systems were characterized for particle size, polydispersity index, and entrapment efficiency (EE), by dynamic laser diffraction and ultrafiltration or dialysis methods, respectively. The results indicated(More)
