  • Publication number: 20030064034
    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.

  • Publication number: 20030064031
    Abstract: The present invention relates to an inhaled formulation comprising a combination of a compound selected from a particular class of 5,6-dihydro-9H-pyrazolo[3,4-c]-1,2,4-triazolo[4,3-a]pyridines of the formula (I) and a tiotropium salt or solvate thereof, which is capable of delivering the compound of the formula (I) as fine, solid particles to the lung. The invention also relates to 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 the compounds of the formula (I) in solution metered dose inhalers, which response can prevent the administration of a therapeutically effective dose and, in the long term, undermine patient compliance.

  • Patent number: 6109261
    Abstract: There is provided a device for the administration of an inhalation medicament, including a body defining a through-going air pathway having a longitudinal axis, an air inlet, an air outlet forming a mouthpiece, means for dispensing medicament into the pathway and air flow regulating means, characterized in that the air flow regulating means includes a movable obstructing means adapted to reduce the cross-sectional area of the pathway at a location between the air inlet and the means for dispensing medicament, and biassing means, whereby the obstructing means is biassed into a first resting position in which the cross-sectional area of the pathway is minimum and is adapted to move against the bias of the biassing means to a second position in which the cross-section area of the pathway is maximum in response to a pressure fall at the mouthpiece caused by inhalation and is adapted to move farther to a third position in which the cross-sectional area of the pathway is less than maximum in response to a greater p
