摘要：
Dry powder formulations for inhalation comprising spray-dried particles and their use in the treatment of an obstructive or inflammatory airways disease. Each particle has a core of a first active ingredient in substantially crystalline form that is coated with a layer of a second active ingredient in substantially amorphous form that is dispersed in a pharmaceutically acceptable hydrophobic excipient. A process for preparing such formulations is also described.
