<p>PCT No. PCT/GB93/01851 Sec. 371 Date Mar. 1, 1995 Sec. 102(e) Date Mar. 1, 1995 PCT Filed Sep. 1, 1993 PCT Pub. No. WO94/05358 PCT Pub. Date Mar. 17, 1994A drug capsule comprises a sleeve forming a side wall of the capsule and having first and second end caps which close the opened ends of the sleeve. The end faces of the end caps are frangible so that they can be ruptured by the open ends of the sleeve by causing the end caps to be displaced along the sleeve towards one another to open the capsule. A dispenser is formed from the combination of the capsule and a pair of elements, each element being adapted to receive a respective one of the end caps so that the capsule interconnects the elements, whereby the capsule can be opened by moving the elements towards one another. One of the elements provides a mouth piece and the other element provides an air flow passageway provided with a turbine to induce turbulence in the air flow through the capsule. The drug capsule and dispenser are primarily intended for administering powdered drugs by inhalation.</p> |
