Solid lipid nanoparticles (SLN) as alternative intravenous colloidal drug carriers were produced by high pressure homogenisation of the melted lipid cetylpalmitate. The crystallographic properties of the used cetylpalmitate SLN were characterised by small angle X-ray scattering (SAXS) and X-ray diffraction (XRD). It was found that the SLN are available(More)
A method for determination of drug substances solubility in lipophilic solvents is presented. The solubility was determined in lipophilic suppository bases meltings, in pharmaceutical lipoids as Oleum Ricini, Oleum Arachidis, Cera perliquida, Paraffinum perliquidum and in chemically defined lipoids as n-hexadecane, 1-hexadecane, cetylic alcohol, palmitic(More)
Solubility of 18 drugs used in rectal therapy in molten suppository base, (Massa suppositoriorum 15, Pharmacopeia of the G.D.R. Rosupol U, 37 degrees C) is determined. Separation of drug-saturated base from drug cristals is carried out in an air-heated centrifuge followed by a partition step between petroleum ether and an aqueous medium and photometrical(More)
