Quercetin Loaded Nanostructured Lipid Carriers for Nose to Brain Delivery: In Vitro and In Vivo Studies

Nehal L Patil and Hitendra S Mahajan

The main objective of the study was to utilize potential of nanostructured lipid carriers of the quercetin for direct nose to brain delivery of drug as tool for the targeted delivery. The aim of this study was to prepare and characterize quercetin loaded NLC and to study its brain distribution. Novel QUE-NLCs were formulated. NLC Formulation was evaluated for various physicochemical properties such as particle size, zeta potential, drug loading, percent entrapment efficiency, morphology, in vitro drug release, and histopathology. The size of the QUE-NLC was about 118.2nm with poly dispersity index of 0.220 and zeta potential of -20.1 mV. Nose to brain distribution studies were performed using wistar rats.QUE-NLC exhibited sustained delivery of drug. Significant targeting to brain was achieved when compare to quercetin.The result showed that NLCs might be the promising approach for the nose to brain delivery of quercetin.
