Vitamin E loaded resveratrol nanoemulsion for brain targeting for the treatment of Parkinson’s disease by reducing oxidative stress
Open accessAbstract
Resveratrol, a potent natural antioxidant, possesses a wide range of pharmacological activities, but its oral bioavailability is very low due to its extensive hepatic and presystemic metabolism. The aim of the present study was to formulate a kinetically stable nanoemulsion (o/w) using vitamin E:sefsol (1:1) as the oil phase, Tween 80 as the surfactant and Transcutol P as the co-surfactant for the better management of Parkinson's disease. The nanoemulsion was prepared by a spontaneous emulsification method, followed by high-pressure homogenization. Ternary phase diagrams were constructed to locate the area of nanoemulsion. The prepared formulations were studied for globule size, zeta potential, refractive index, viscosity, surface morphology and in vitro and ex vivo release. The homogenized formulation, which contained 150 mg ml(-1) of resveratrol, showed spherical globules with an average globule diameter of 102 ± 1.46 nm, a least poly dispersity index of 0.158 ± 0.02 and optimal zeta potential values of -35 ± 0.02. The cumulative percentage drug release for the pre-homogenized resveratrol suspension, pre-homogenized nanoemulsion and post-homogenized nanoemulsion were 24.18 ± 2.30%, 54.32 ± 0.95% and 88.57 ± 1.92%, respectively, after 24 h. The ex vivo release also showed the cumulative percentage drug release of 85.48 ± 1.34% at 24 h. The antioxidant activity determined by using a DPPH assay showed high scavenging efficiency for the optimized formulation. Pharmacokinetic studies showed the higher concentration of the drug in the brain (brain/blood ratio: 2.86 ± 0.70) following intranasal administration of the optimized nanoemulsion. Histopathological studies showed decreased degenerative changes in the resveratrol nanoemulsion administered groups. The levels of GSH and SOD were significantly higher, and the level of MDA was significantly lower in the resveratrol nanoemulsion treated group.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
