The present study investigated the release profiles of insulin from Pluronic F-127 (PF-127) gel containing unsaturated fatty acids such as oleic acid (18:1), eicosapentaenoic acid (20:5) or docosahexaenoic acid (22:6) and the hypoglycemic effect of insulin following the buccal administration of the gel formulations in normal rats. Insulin release from the gels decreased in the presence of unsat...

BACKGROUND AND OBJECTIVES Rheological evaluation of thermoreversible mucoadhesive nasal gel of zolmitriptan is done to determine the steady shear behaviour and gelation temperature. The thermoreversible mucoadhesive polymers are sucessesfully used to increase the contact time of the therapeutic compound in the nasal cavity as well as they cause enhancement in permeation of drug through the nasa...

The challenge in developing oral drug delivery systems of poorly soluble basic drugs is primarily due to their pH dependent solubility. Cinnarizine (CNZ), a model for a poorly soluble basic drug, has pH dependent solubility; where it dissolves readily at low pH in the stomach and exhibits a very low solubility at pH values greater than 4. It is also characterized by a short half life of 3-6h, w...

Zebrafish embryos selected at the 64-cell stage were exposed to various concentrations of amide functionalized single-walled carbon nanotubes (SWCNTs) ranging from 1 to 10 μg/ml dissolved in 1% Pluronic F-68 (a cell culture grade surfactant), and the development of embryos was examined from 24 to 120 hours post fertilization (hpf). Incubation of embryos in 1% F-68 did not induce overt abnormal ...

The purpose of this study was to prepare and evaluate the intravenous emulsion (BCOE) containing Brucea javanica oil (BJO) and Coix seed oil (CSO), which is used in anti-tumor treatment. The formulation and preparation of BCOE were systematically investigated. High-pressure homogenization, particle size distribution, zeta-potential and HPLC were carried out. The pharmacokinetics of the main com...

Gold nanoparticle-coated Pluronic-b-poly(L-lysine) nanoparticles (Pluronic-PLL@Au NPs) were synthesized via an easy one-step method and employed as carriers for the delivery of paclitaxel (PTX) in chemo-photothermal therapy, in which Pluronic-PLL acts as the reductant for the formation of AuNPs without the need for an additional reducing agent. METHODS The deposition of AuNPs on the surface o...

The aim of the present study was to develop Exemestane loaded polymeric nanoparticles for improved oral bioavailability of Exemestane. Exemestane loaded nanoparticles were prepared by solvent displacement method with Eudragit RL 100 and Eudragit L 100 as polymers and Pluronic® F-68 as surfactant. The influence of various formulation factors (drug: polymer ratio and concentration of surfactant) ...
