    • The present invention provides a nasal drug delivery composition comprising nicotine or a pharmacologically-acceptable salt or derivative thereof wherein the composition is adapted to delivery a pulse of nicotine for rapid absorption and a controlled release of nicotine for subsequent sustained absorption. The controlled release phase can be achieved by providing an ion-exchange material which will form a complex with the nicotine. The ion-exchange material may be a polymeric material such as a polysaccharide, or may be in the form of bioadhesive ion-exchange microspheres. The pulse release can be achieved by overloading the ion-exchange material with nicotine so that the composition contains some excess nicotine for immediate release and absorption. Alternatively, some nicotine may be associated with a non ion-exchange material which will release the nicotine immediately on contact with the nasal mucosa, for example non-ion-exchange bioadhesive microspheres.

    • Compositions for delivery of pharmacologically active agents and methods for their administration are provided. In one embodiment, the compositions include a complex of a polycationic polymer and a pharmacologically active agent in a pharmaceutically acceptable carrier. The compositions in one embodiment permit transport of pharmacologically active compounds across mucosal membranes for systemic delivery. The polycationic polymer may be, for example, a polycationic carbohydrate such as a chitosan or a chitosan salt or derivative. The therapeutic agent a preferred embodiment is a vaccine or a nucleic acid, such as a gene or antisense oligonucleotide. The composition may be provided in different forms such as a solution, dispersion, powder or in the form of microspheres.
    • 提供用于递送药理学活性剂的组合物及其给药方法。 在一个实施方案中,组合物包括在可药用载体中的聚阳离子聚合物和药理活性剂的复合物。 在一个实施方案中的组合物允许药物活性化合物跨越粘膜进行系统递送。 聚阳离子聚合物可以是例如聚阳离子碳水化合物如壳聚糖或壳聚糖盐或衍生物。 治疗剂优选的实施方案是疫苗或核酸,例如基因或反义寡核苷酸。 组合物可以以不同形式提供,例如溶液,分散体,粉末或微球形式。

    • Hollow microcapsules or solid microspheres for use in diagnostic procedures, as well as methods for making the microcapsules, are provided, which are formed by combining a volatile oil with an aqueous phase including a water soluble material such as a starch, modified starch or proteinaceous material, or a polyethylene glycol (PEG) conjugate, to form a primary emulsion. The primary emulsion then is combined with a second oil, to form a secondary emulsion, and the material is permitted to harden and to form microcapsules around a liquid core of the volatile oil. At least part of the volatile oil then may be removed by evaporation to produce hollow microcapsules. Optionally, all of the volatile oil may be removed prior to hardening of the material, which produces solid microspheres. The The microcapsules can be used in a variety of applications for diagnostic purposes and for drug delivery.
