Abstract:
The present invention is concerned with a refinement of the processing of particles that are to form a dry powder formulation which is to be administered to the lung using a dry powder inhaler (DPI) device. In particular, the present invention provides the processing of particles of active material and particles of carrier material in the presence of additive material to provide a powder composition which exhibits excellent powder properties and which is economical to produce.
