摘要： The present invention generally relates to reducing the mucoadhesive properties of a particle. In some embodiments, the particle is coated with and/or associated with a (poly(ethylene glycol))-(poly(propylene oxide))-(poly(ethylene glycol)) triblock copolymer. Methods for preparing inventive particles using a poly(ethylene glycol)-vitamin E conjugate as a surfactant are also provided. In some embodiments, methods are provided comprising administering to a subject a composition of particles of the present invention. Such particles with reduced mucoadhesive properties are useful in delivering agents to mucosal tissues such as oral, ophthalmic, gastrointestinal, nasal, respiratory, and genital mucosal tissues.

摘要： Improved aerodynamically light particles for drug delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the aerodynamically light particles are made of biodegradable material and have a tap density of less than 0.4 g/cm3 and a mass mean diameter between 5 μm and 30 μm. 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 α-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, aerodynamically light particles having a large mean diameter, for example greater than 5 μm, can be used for enhanced delivery of a therapeutic agent to the alveolar region of the lung. The aerodynamically light 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： Aerodynamically light particles incorporating a surfactant on the surface thereof for drug delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the aerodynamically light particles are made of a biodegradable material and have a tap density less than 0.4 g/cm.sup.3 and a mass mean diameter between 5 .mu.m and 30 .mu.m. The particles may be formed of biodegradable materials such as biodegradable polymers. For example, the particles may be formed of poly(lactic acid) or poly(glycolic acid) or copolymers thereof. Alternatively, the particles may be formed solely of the drug or diagnostic agent and a surfactant. Surfactants can be incorporated on the particle surface for example by coating the particle after particle formation, or by incorporating the surfactant in the material forming the particle prior to formation of the particle. Exemplary surfactants include phosphoglycerides such as L-.alpha.-phosphatidylcholine dipalmitoyl. The aerodynamically light particles incorporating a therapeutic or diagnostic agent and a surfactant may be effectively aerosolized for administration to the respiratory tract to permit systemic or local delivery of wide a variety of therapeutic agents.
