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...
