    摘要： The present invention relates to methods of making and compositions of microencapsulated small particles of an active agent. In accordance with the method of production, the active agent is dissolved in an aqueous or aqueous-miscible solvent containing a dissolved phase-separation enhancing agent (PSEA) to form a solution in a single liquid phase. The solution is then subjected to a liquid-solid phase separation to cause the active agent to form solid spherical small particles in the solid phase while the PSEA and solvent comprising the liquid phase. The spherical small particles formed are then microencapsulated within a polymeric matrix using an emulsion/evaporation process.

    摘要： Compositions of spherical insulin particles having improved pulmonary application potentials and methods of forming and using these compositions are disclosed in the present application. In one clinical trial with 30 healthy male human subjects, no coughing was observed upon a single pulmonary administration of the spherical insulin particles at an insulin dose of 6.5 mg, nor during the 10-hour post dosing period.

    摘要： The present invention is related to a method for preparing small spherical particles of an active agent by providing a solution in a single liquid phase. The single liquid phase comprises an active agent, a phase separation enhancing agent, and a first solvent. A phase change is induced at a controlled rate in the solution to cause a liquid-solid phase separation of the active agent and to form a solid phase and a liquid phase. The solid phase comprises solid small spherical particles of the active agent. The liquid phase comprises the phase separation enhancing agent and the solvent. The small spherical particles are substantially spherical and having a size from about 0.01 μm to about 200 μm.
