摘要:
Dry powder formulations for inhalation and their use in the treatment diseases and conditions. The formulation contains a uniform blend of a first spray-dried powder and a second spray-dried powder. The first spray-dried powder contains spray-dried particles of a therapeutically active ingredient dispersed in a pharmaceutically acceptable hydrophobic excipient. The second spray-dried powder contains spray-dried particles formed from a pharmaceutically acceptable hydrophobic excipient but are substantially free of any therapeutically active ingredient. The active ingredient in the first spray-dried powder is loaded sufficiently high to compensate for the second spray-dried powder being substantially free of any active ingredient. A process for preparing such formulations is also described.
