    摘要: Described are solid dose nanoparticulate naproxen formulations having high rates of dissolution. The solid dose nanoparticulate naproxen formulations can comprise an alkali compound, which functions to increase the dissolution rate of the naproxen following administration. Alternatively, the solid dose nanoparticulate naproxen formulation can comprise an alkali compound and an acidic compound, which can react together to form carbon dioxide. The formed carbon dioxide can also aid in increasing the dissolution rate of the naproxen following administration. Also described are solid dose nanoparticulate naproxen formulations having a decreased concentration of a binder/disintegrant agent. Such compositions also provide an increased rate of dissolution of naproxen following administration.

    摘要: Methods for stabilizing chemical compounds, particularly pharmaceutical agents, using nanoparticulate compositions are described. The nanoparticulate compositions comprise a chemical compound, such as a pharmaceutical agent, and at least one surface stabilizer. The component chemical compound exhibits chemical stability, even following prolonged storage, repeated freezing-thawing cycles, exposure to elevated temperatures, or exposure to non-physiological pH conditions.

    摘要: The present invention is directed to methods for preventing crystal growth and particle aggregation in nanoparticulate compositions. The methods comprise reducing a nanoparticulate composition to an optimal effective average particle size. The resultant nanoparticulate compositions exhibit prolonged particle size stability and minimal crystal growth, even following exposure to elevated temperatures.
