  • Patent number: 5522383
    Abstract: An inhaler for inhaling pulverulent medicament from within a capsule comprises a chamber (24) within which the capsule is free to rotate while having its longitudinal axis in the median plane of the chamber and thus generally parallel to the front and rear walls (30) and (31) of the chamber, by virtue of the fact that the spacing between said front and rear walls is less than the axial length of the capsule but just greater than the diameter of the capsule. The device includes pins (21) serving as opening means to pierce the ends of the capsule while it is seated in a recess (25), whereupon the retraction of the pins (21) allows the capsule to be entrained into swirling airflow in the chamber (24) during inhalation of air through air inlets (26) and out through a mouthpiece nozzle (27).

  • Patent number: 5413782
    Abstract: In a method in which an ionizable pharmaceutical material, such as theophylline, having a pharmaceutically-active anionic group is bonded to an anion exchange resin having cationic groups bonded to displacable anionic groups by bringing said material and said resin into contact with each other under conditions such that the pharmaceutically-active anionic group of said material is bonded to the cationic group of said resin and replaces the anionic group thereof, the improvement comprising effecting said contact in an environment which is substantially free of carbon dioxide and/or bicarbonate ion, a pharmacologically active composition comprising said pharmaceutically active anion and said resin, including a composition in which at least about 40% of the binding capacity of the resin comprises said pharmaceutically active anion, and a sustained release pharmaceutical composition, including enteric coated particles of the composition, and stabilizing said composition by maintaining it in an environment substan
