  • Patent number: 7658998
    Abstract: The present invention relates to a method for preparing an injectable composition of microparticles for the sustained release of a biologically active agent. The microparticles include a biocompatible polymer and a biologically active agent. The invention provides an improved process for the preparation of microparticles, wherein the physical characteristics of the microparticles, for example, the morphology, density and size, are independent of the process used to prepare the initially formed polymer/drug matrix. The method includes the steps of (a) providing a polymer/biologically active agent matrix; (b) compressing the polymer/biologically active agent matrix, thereby forming a compressed matrix; and (c) fragmenting the compressed matrix, thereby forming an injectable microparticle composition. The polymer/drug matrix can be provided by any suitable method.

  • Publication number: 20090194894
    Abstract: Methods for preparing microparticles having reduced residual solvent levels. Microparticles are contacted with a non-aqueous washing system to reduce the level of residual solvent in the microparticles. Preferred non-aqueous washing systems include 100% ethanol and a blend of ethanol and heptane. A solvent blend of a hardening solvent and a washing solvent can be used to harden and wash microparticles in a single step, thereby eliminating the need for a post-hardening wash step.

  • Patent number: 7556798
    Abstract: A method for delivering an agent to the pulmonary system, in a single, breath-activated step or a single breath, comprises administering from a receptacle enclosing a mass of particles, to a subject's respiratory tract, particles which have a tap density of less than 0.4 g/cm3 and deliver at least about 50% of the mass of particles. The particles are capable of carrying agents. The agent is (1) part of the spray-drying pre-mixture and thereby incorporated into the particles, (2) added to separately-prepared particles so that the agent is in chemical association with the particles or (3) blended so that the agent is mixed with, and co-delivered with the particles. Respirable compositions comprising carrier particles having a tap density of less than 0.4 g/cm3 and a composition comprising an agent are also disclosed. Methods of delivering these respirable compositions are also included.

  • Publication number: 20090022823
    Abstract: The present invention relates, in part, to the discovery that parenterally administered extended release formulations possess an unexpected advantage in treating patients possessing active CYP 3A4. This advantage is particularly beneficial where the individual is concomitantly administering a CYP 3A4 inhibitor or is in risk of doing so. Thus, the invention relates to a method for treating individuals possessing a functional CYP3A4 gene with an active agent metabolized by CYP3A4 comprising parenterally administering the active agent in a first extended release formulation in a first administration and the formulations for use in such methods. The invention further includes a method for preventing adverse drug reactions in individuals possessing a functional CYP3A4 gene with an active agent metabolized by CYP3A4 comprising parenterally administering the active agent in a first extended release formulation in a first administration.

  • Patent number: 7469488
    Abstract: Spray dried particles having specified aerodynamic characteristics are produced by atomizing a liquid feed and contacting the liquid feed with a drying gas, such as, for example, air or nitrogen. The humidity of the drying gas is controlled to a value, expressed, for instance, as dew point, which is known to produce particles having a specified tap density or aerodynamic diameter. Particles having a volume median geometric diameter greater than about 5 microns and a tap density less than about 0.4 g/cm3 are preferred.
