    摘要: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful election of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry powder comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

    摘要: A multiparticulate bisoprolol formulation for once-daily oral administration, each particle of which comprises a core of bisoprolol or a pharmaceutically acceptable salt thereof surrounded by a polymeric coating, the polymeric coating being effective to achieve an initial lag of bisoprolol release in vivo of at least 4-6 hours following administration and thereafter maintaining therapeutic concentrations of bisoprolol for the remainder of the twenty-four hour period. The formulation can be used for night-time dosing so as to minimize the likelihood of acute cardiovascular occurrences in the well-documented high risk period in the morning.

    摘要: Small diameter particles of biologically active molecules are produced by atomizing solutions of the molecules through a nozzle into very cold liquified gases, which immediately freeze the atomized droplets. The resulting frozen particles having diameters of approximately 10 to 90 micrometers are lyophilized to produce porous particles, suspended in a non-solvent for the molecules, and exposed to ultrasonic energy or homogenization to produce particles having diameters of 0.1 to 10 micrometers with greater than 70 to 95% of the initial biological activity of the molecules in solution.
