The present invention relates to the delivery of beta-blockers through an inhalation route. Specifically, it relates to aerosols containing atenolol, pindolol, esmolol, propranolol, or metoprolol that are used in inhalation therapy. In a composition aspect of the present invention, the aerosol comprises particles comprising at least 5 percent by weight of atenolol, pindolol, esmolol, propranolol, or metoprolol. In a method aspect of the present invention, one of atenolol, pindolol, esmolol, propranolol, or metoprolol is delivered to a mammal through an inhalation route. The method comprises: a) heating a composition, wherein the composition comprises at least 5 percent by weight of atenolol, pindolol, esmolol, propranolol, or metoprolol, to form a vapor; and, b) allowing the vapor to cool, thereby forming a condensation aerosol comprising particles, which is inhaled by the mammal. In a kit aspect of the present invention, a kit for delivering atenolol, pindolol, esmolol, propranolol, or metoprolol through an inhalation route to a mammal is provided which comprises: a) a composition comprising at least 5 percent by weight of atenolol, pindolol, esmolol, propranolol, or metoprolol; and, b) a device that forms a atenolol, pindolol, esmolol, propranolol, or metoprolol containing aerosol from the composition, for inhalation by the mammal.
本发明涉及通过吸入途径给药β-受体阻滞剂。具体而言,本发明涉及用于吸入治疗的含有阿替洛尔、吲哚洛尔、艾司洛尔、普萘洛尔或美托洛尔的气雾剂。在本发明的组合物方面,气雾剂包括至少 5%(按重量计)阿替洛尔、吲哚洛尔、艾司洛尔、普萘洛尔或美托洛尔的颗粒。在本发明的一个方法方面,通过吸入途径将阿替洛尔、吲哚洛尔、艾司洛尔、普萘洛尔或美托洛尔中的一种递送给哺乳动物。该方法包括:a) 加热一种组合物,其中该组合物包含按重量计至少5%的阿替洛尔、吲哚洛尔、艾司洛尔、普萘洛尔或美托洛尔,以形成蒸气;b) 让蒸气冷却,从而形成包含颗粒的冷凝气溶胶,由哺乳动物吸入。在本发明的一个试剂盒方面,提供了一种通过吸入途径向哺乳动物提供阿替洛尔、吲哚洛尔、艾司洛尔、普萘洛尔或美托洛尔的试剂盒,该试剂盒包括:a) 一种组合物,按重量计至少含有 5%的阿替洛尔、吲哚洛尔、艾司洛尔、普萘洛尔或美托洛尔;以及 b) 一种装置,从组合物中形成含有阿替洛尔、吲哚洛尔、艾司洛尔、普萘洛尔或美托洛尔的气溶胶,供哺乳动物吸入。
