pluronic/bile salt/phospholipid mixed micelles (pluronic/bs/ps-mm) drug carrier system for solubilization hydrophobic drugs was developed. a typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. five pluronics, f68, f88, f98, f108, and f127 with different ppo chain length were studied. cmc data and solubilization capacities w...

Multidrug resistance (MDR) in tumor cells is a significant obstacle to the success of chemotherapy in many cancers. The purpose of this research is to test the possibility of docetaxel-loaded poly (e-caprolactone)/Pluronic F68 (PCL/Pluronic F68) nanoparticles to overcome MDR in docetaxel-resistance human breast cancer cell line. Docetaxel-loaded nanoparticles were prepared by modified solvent d...

The human immunodeficiency virus 1 (HIV-1) still remains one of the leading life-threatening diseases in the world. The introduction of highly active antiretroviral therapy has significantly reduced disease morbidity and mortality. However, most of the drugs have variable penetrance into viral reservoir sites, including gut-associated lymphoid tissue (GALT). Being the largest lymphoid organ, GA...

The treatment of squamous carcinoma, especially multidrug resistance (MDR) tumors, represents one of the most formidable challenges in oncology. In this study, integrin-mediated Pluronic-based micellar system (c(RGDyK)-FP-DP) was proposed as a drug delivery system to enhance the in vivo anti-tumor efficacy in MDR human squamous carcinoma (KBv)-bearing. Following the recognition by integrin prot...

conclusions this study demonstrated that physicochemical properties, in vitro release and rat intestine permeability were dependent upon the contents of s/c, water and oil percentage in formulations. background self-emulsifying drug delivery system is an isotropic mixture of natural or synthetic oils, non-ionic surfactants or, one or more hydrophilic solvent and co-solvents/surfactant and polym...

objective(s): the aim of this work was to prepare and characterize magnetic nanoparticles (mnps) as theranostic system to act simultaneously as drug carrier and mri contrast agent. chitosan-coated mnps (cmnps) were prepared and loaded with silymarin. silymarin-loaded cmnps were characterized with various techniques and their potential as mri contrast agent was also evaluated. materials and meth...

This investigation describes the formulation and characterization of rheologically structured vehicles (RSVs) designed for improved drug delivery to the vagina. Interactive, multicomponent, polymeric platforms were manufactured containing hydroxyethylcellulose (HEC, 5% w/w) polyvinylpyrrolidone (PVP, 4% w/w), Pluronic (PL, 0 or 10% w/w), and either polycarbophil (PC, 3% w/w) or poly(methylvinyl...
