Solid lipid nanoparticles (SLN) as alternative intravenous colloidal drug carriers were produced by high pressure homogenisation of melted lipids (glycerolbehenate, cetylpalmitate). Their surface was modified by using hydrophilic poloxamine 908 and poloxamer 407 blockcopolymers in order to reduce the phagocytic uptake by the reticuloendothelial system (RES)(More)
Solid lipid nanoparticles (SLN) composed of two different lipid matrices were produced to assess their in vivo toxicity in mice. Matrix substances were (i) Compritol (glycerol behenate), a physiological lipid with GRAS status (generally recognized as safe [FDA]), and (ii) cetyl palmitate, a less physiological compound. Physicochemical data proved the(More)
