A dose strip (60) for use with a powder inhaler (50) includes a base strip (76) having spaced apart blisters (78) containing a pharmaceutical powder (80). A lid strip (84) is attached over the base strip (76), sealing the pharmaceutical powder (80) within the blisters (78). Lid tabs (82) are attached to the lid strip (84) over each blister. A peel strip or string (86) is joined to each lid tab (82). The dose strip (60) is preferably wound into a compact coil, so that it may be contained within an inhaler (50). To access a dose of pharmaceutical powder (80), the peel strip (86) is pulled away from the base strip (76) and lid strip (84), causing a lid tab (82) to shear open the lid strip (84). The peel strip (86) and attached lid tabs (82) are wound on a first take up reel (62), and the base strip (76) and lid strip (84) are separately wound on a second take up reel (64), within the inhaler (50), after a dose within each blister is accessed. |
