Nanostructured lipid carriers (NLC) developed from mixtures of solid lipid and spatially incompatible liquid lipid by solvent diffusion method. This new type of lipid nanoparticles offers the advantage of improved drug loading capacity and release properties. In this study, Glyceryl distearate and Glyceryl behenate were chosen as solid lipid and Glyceryl triacetate used as liquid lipid. Ubidecarenone used as model drug was incorporated into the NLC. The influences of different type of solid lipid and liquid lipid concentration on physiochemical properties of the NLC were characterized. As a result, the drug encapsulation efficiencies were improved by adding the liquid lipid into the solid lipid of nanoparticles. NLC had higher encapsulation efficiency and drug release. In addition, in vivo study showed that the antioxidant activity of the Ubidecarenone (Co. Q10 NLC) was more effective than the Ubidecarenone (Coenzyme Q10) solution form on DPPH scavenging, anti-lipid peroxidation, lowers the effect of amnesia induced by scopolamine and increased bioavailability observed in C max, T max, and AUC. These results indicated that nanostructured lipid formulation of Ubiquinone (Coenzyme Q10) has more antioxidant activity than that of solution form and it can be used to reduce the oxidative stress and to increase the antioxidant enzyme activity in many neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease etc.
