Abstract:
The present invention relates to an inhaled formulation comprising a compound selected from a particular class of 5,6-dihydro-9H-pyrazolo[3,4-c]-1,2,4-triazolo[4,3-a]pyridines which is capable of delivering the compound as fine, solid particles to the lung and the use of such a formulation in the treatment of certain diseases such as respiratory diseases. By the use of such formulations, it is possible to eliminate the unwanted cough response associated with the use of these compounds in solution metered dose inhalers, which response can prevent the administration of a therapeutically effective dose and, in the long term, undermine patient compliance.
