Curcumin and Rutin are natural polyphenolic molecules exhibits several pharmacological actives like antibacterial, anticancer, antioxidant, chemo-preventive and anti-inflammatory properties. However till date, no studies have been reported on their combination efficacy, especially in treating multi-drug resistance of cancers because of their poor solubility and bioavailability. Hence in the present study, an attempt has been made to load both these drugs into a single nanoparticlulate system to enhance their bioavailability and efficacy. This novel formulation was prepared by solvent evaporation technique and was evaluated for particle size and shape using Zeta Sizer, Scanning Electron Microscopy (SEM) and Fourier Transform Infra Red (FT-IR) Spectroscopy. The optimized formulation was further subjected to in vitro and in vivo evaluations. The prepared nanoparticles were in the size range of 25–100nm and the release profile was found to be Non −Fickian transport. In-vivo pharmacokinetic studies were carried in rabbits and the pharmacokinetic profile was studied. The results indicate that oral bioavailability of Curcumin and Rutin has been increased to 3.06 and 4.24 folds respectively when compared to their pure drugs. This data suggest that the present novel nanoparticles loaded with these combinational drugs may have better therapeutic potential in treating drug resistant cancers.
