    • 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 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 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 are expected to have a significantly prolonged shelf-life than currently available nanoemulsions.
    • 本发明公开了一种改进的纳米乳液,其包含非常小的粒子纳米尺寸直径的均匀和离散范围。 这种均匀性导致了各种药代动力学参数中反映的掺入化合物(即药物或营养药物)的生物利用度的改善,其包括但不限于降低的最大值。 ,并增加AUC。 与用于产生纳米颗粒组合物的常规研磨和研磨技术相比,制备这些均匀纳米乳液的改进方法利用微流化,其在工艺和力学上都不同。 此外,改进结果部分地从将基本上可溶的化合物混合到加热的分散介质中的新步骤。 这与将不溶性化合物与未加热的分散介质混合的当前纳米颗粒组合物方法不同。 此外,观察到这些纳米乳液在温度和pH变化中都具有细菌抗性并且极端稳定。 因此,预期这些纳米乳液比目前可获得的纳米乳液具有显着延长的保存期限。
