DRUG FORMULATIONS COMPRISING COATED, VERY SPARINGLY WATER-SOLUBLE DRUGS FOR INHALATIONAL PHARMACEUTICAL FORMS, AND PROCESS FOR THEIR PREPARATION

摘要

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.
