The present invention relates to the treatment of dry powder formulations, doses of which are measured out and placed into receptacles such as blisters or capsules, to be dispensed by a dry powder inhaler device (DPI). In particular, the present invention relates to methods of agitating a dose of a dry powder formulation to ensure that any compacted powder is broken up. It is easier to extract a loose powder from a receptacle than it is to extract powder which is compacted and so ensuring that the powder in a receptacle is not compacted can, in turn, lead to improvements in the administration of the powder formulation to the lung of the patient. |
