Abstract
Drug formulations comprising coated, very sparingly water-soluble drugs for inhalational pharmaceutical forms, and process for their preparation. Drug formulations comprising micronized particles of very sparingly water-soluble drugs which are coated with a natural, physiologically acceptable ampholytic surfactant soluble in water to give a micellar/colloidal solution, and a process for the preparation of these drug formulations, are described. When placed in an appropriate final container and after the addition of a chlorine-free, partially fluorinated propellant gas liquefiable under pressure, these formulations are suitable for inhalation.
