摘要:
Described are controlled release nanoparticulate formulations comprising a nanoparticulate agent to be administered and a rate-controlling polymer which functions to prolong the release of the agent following administration. The novel compositions release the agent following administration for a time period ranging from about 2 to about 24 hours or longer.
摘要:
Nanoparticulate compositions comprising at least one poorly soluble MAP kinase inhibitor and at least one surface stabilizer are described. The nanoparticulate compositions have an average particle size of less than about 2000 nm. The invention also describes methods of making and using such compositions.
摘要:
A pharmaceutical composition for the oral or parenteral administration of a compound of Formula (I) comprising an oil in water emulsion, wherein the oil phase comprises the free base of or a pharmaceutically acceptable salt thereof of a compound of Formula (I), and one or more surfactants which are soluble in the oil phase and/or the aqueous phase. The emulsion optionally contains one or more excipients that are soluble in the oil phase and/or the aqueous phase, such as pH modifying agents such as buffers, osmolality/tonicity modifying agents, emulsifying agents, water-soluble polymers, and preservatives. The compound of Formula (I) can be formulated as a solid material and stored until needed. Kits for forming the emulsion are provided. Prior to administration, the solid material can be reconstituted in an aqueous medium to form the emulsion.
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.
