Novel formulations that overcome the solubility limitations of poorly water soluble drugs (PWSD) are becoming ever more critical to a drug development process inundated with these compounds. There is a clear need for developing bio-enabling formulation approaches to improve oral

The objective of this study was to develop novel docetaxel phospholipid nanoparticles (NDPNs) for intravenous administration. Modified solvent diffusion-evaporation method was adopted in the NDPN preparation. Central composite design (CCD) was employed in the optimization of the critical formulation factor

The current study determined the extent to which the desorption of lipid-based formulations (LBFs) from a mesoporous magnesium aluminometasilicate (Neusilin®-US2) carrier is governed by drug properties, LBF composition, and LBF-to-adsorbent ratio. A secondary objective was to evaluate the impact of

The Lipid Formulation Classification System Consortium looks to develop standardized in vitro tests and to generate much-needed performance criteria for lipid-based formulations (LBFs). This article highlights the value of performing a second, more stressful digestion test to identify LBFs near

For over 20years, stealth drug delivery has been synonymous with nanoparticulate formulations and intravenous dosing. The putative determinants of stealth in these applications are the molecular weight and packing density of a hydrophilic polymer (commonly poly(ethylene glycol) (PEG)) that forms
