Abstract
Powdery pharmaceutical compositions including an active ingredient and carrier particles containing only a small amount of lubricant, 0.1-0.5% by weight, are used to prepare dry powder inhalers in order to increase the fine particle dose. A process for coating the surface of the carrier particles with such little amount of lubricant is also provided. Use of limited amount of lubricant is safe and provides ordered stable mixtures without segregation of the active particles during handling and before use.
