C:/NRPorlbl/DCC/SCG/4907465_ .DOC-5102/2013 Abstract The present invention discloses an improved nanoemulsion comprising a uniform and discrete range of very small particle nano-sized diameters. This uniformity results in improved 5 bioavailability of incorporated compounds (i.e., pharmaceuticals or nutraceuticals) as reflected in various pharmacokinetic parameters including, but not limited to, decreased Tmax, increased Cmax, and increased AUC. The improved method of making these uniform nanoemulsions utilizes microfluidization which differs in both process and mechanics when compared to conventional milling and grinding techniques used to generate nanoparticulate 10 compositions. Further, the improvement results, in part, from a novel step of mixing a substantially soluble compound into a heated dispersion medium. This is unlike current nanoparticulate composition methods that mix an insoluble compound with an unheated dispersion medium. Further, these nanoemulsions are observed to be bacterial-resistant and stable to extremes in both temperature and pH changes. Consequently, these nanoemulsions 15 are expected to have a significantly prolonged shelf-life than currently available nanoemulsions. |
