    摘要: Improved porous particles for drug delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the porous particles are made of a biodegradable material and have a mass density less than 0.4 g/cm3/. The particles may be formed of biodegradable materials such as biodegradable polymers. For example, the particles may be formed of a functionalized polyester graft copolymer consisting of a linear &agr;-hydroxy-acid polyester backbone having at least one amino acid group incorporated therein and at least one poly(amino acid) side chain extending from an amino acid group in the polyester backbone. In one embodiment, porous particles having a relatively large mean diameter, for example greater than 5 &mgr;m, can be used for enhanced delivery of a therapeutic agent to the alveolar region of the lung. The porous particles incorporating a therapeutic agent may be effectively aerosolized for administration to the respiratory tract to permit systemic or local delivery of wide variety of therapeutic agents.

    摘要: The present invention is based, in part, on the unexpected discovery that particles for pulmonary delivery of a therapeutic, prophylactic or diagnostic agent that comprise a phospholipid and a sufficient amount of leucine can produce sustained effect of the agent. Specifically, particles for pulmonary delivery of a therapeutic, prophylactic or diagnostic agent that contain a phospholipid or combination of phospholipids, wherein the phospholipid or combination of phospholipids is present in the particles in an amount of about 1 to 46 weight percent; and leucine, wherein leucine is present in the particles in an amount of at least 46 weight percent, can contribute to sustained effect of the agent. Particles that comprise at least 46 weight percent leucine but that do not contain phospholipids do not exhibit these same sustained effect properties.
