    摘要： A method is provided for making an oral dosage form of a pharmaceutical agent which includes the steps of (a) providing particles which include a pharmaceutical agent; (b) blending the particles with particles of a pre-processed excipient to form a primary blend, wherein the pre-processed excipient is prepared by (i) dissolving a bulking agent (e.g., a sugar) and at least one non-friable excipient (e.g., a waxy or liquid surfactant) in a solvent to form an excipient solution, and (ii) removing the solvent from the excipient solution to form the pre-processed excipient in dry powder form; (c) milling the primary blend to form a milled pharmaceutical formulation blend that includes microparticles or nanoparticles of the pharmaceutical agent; and (d) processing the milled pharmaceutical formulation blend into a solid oral dosage form or liquid suspension for oral administration. The process yields formulations having improved wettability or dispersibility.

    摘要： Methods are provided for making a dry powder blend pharmaceutical formulation comprising (i) forming microparticles which comprise a pharmaceutical agent; (ii) providing at least one excipient in the form of particles having a volume average diameter that is greater than the volume average diameter of the microparticles; (iii) blending the microparticles with the excipient to form a powder blend; and (iv) jet milling the powder blend to deagglomerate at least a portion of any of the microparticles which have agglomerated, while substantially maintaining the size and morphology of the individual microparticles. Jet milling advantageously can eliminate the need for more complicated wet deagglomeration processes, can lower residual moisture and solvent levels in the microparticles (which leads to better stability and handling properties for dry powder formulations), and can improve wettability, suspendability, and content uniformity of dry powder blend formulations.

    摘要： Pharmaceutical formulations and methods are provided for the sustained delivery of a pharmaceutical agent to a patient by injection. The injectable formulation includes porous microparticles which comprise a pharmaceutical agent and a matrix material, wherein upon injection of the formulation a therapeutically or prophylactically effective amount of the pharmaceutical agent is released from the microparticles for at least 24 hours. A method for making the injectable, sustained release pharmaceutical formulation may include dissolving a hydrophobic matrix material in a volatile solvent to form a first solution; adding a pharmaceutical agent to the first solution to form an emulsion, suspension, or second solution; and removing the volatile solvent from the emulsion, suspension, or second solution to yield porous microparticles which comprise the pharmaceutical agent dispersed, entrapped or encapsulated within the structure of the hydrophobic matrix material.

    摘要： Methods and apparatus are provided for making particles comprising: (a) spraying an emulsion, solution, or suspension, which comprises a solvent and a bulk material (e.g., a pharmaceutical agent), through an atomizer and into a primary drying chamber, having a drying gas flowing therethrough, to form droplets comprising the solvent and bulk material dispersed in the drying gas; (b) evaporating, in the primary drying chamber, at least a portion of the solvent into the drying gas to solidify the droplets and form particles dispersed in drying gas; and (c) flowing the particles and at least a portion of the drying gas through a jet mill to deagglomerate or grind the particles. By coupling spray drying with “in-line” jet milling, a single step process is created from two separate unit operations, and an additional collection step is advantageously eliminated. The one-step, in-line process has further advantages in time and cost of processing.
