Lutein nanocrystals as antioxidant formulation for oral and dermal delivery

International Journal of Pharmaceutics
Khalil MitriRainer H Müller


Lutein is a well known antioxidant and anti-free radical used in cosmetic, nutraceutical industry with potential application in pharmaceutics as supportive antioxidant in treatments. As lipophilic molecule it is poorly soluble in water and has a low bioavailability. Lutein nanosuspension was prepared to enhance dissolution velocity, saturation solubility (C(s)), which are major factors determining oral bioavailability and penetration into the skin. High pressure homogenization (HPH) was used to prepare lutein nanosuspension. Particle size was determined by photon correlation spectroscopy (PCS) and laser diffractometry (LD). The lowest PCS diameter obtained was about 429 nm, the LD diameter 90% of 1.2 μm. The zeta potential was about -40 mV in water and -17 mV in the original dispersion medium. The 3 month storage study at different temperatures (4°C, 25°C, 40°C) confirmed physical stability despite the low zeta potential of -17 mV in original surfactant solution. A pronounced increase in saturation solubility by 26.3 fold was obtained for lutein nanocrystals compared to coarse powder. The lutein nanosuspension was converted into pellets and filled into hard gelatin capsules for nutraceutical use, showed a superior in vitro rele...Continue Reading
