Summary for Patent: 6,645,466

Title:	Dry powder for inhalation
Abstract:	The aim of the invention is to improve the moisture resistance of dry powder formulations for inhalation which contain a pharmaceutically ineffective carrier of not-inhalable particle size and a finely divided pharmaceutically active compound of inhalable particle size and to also improve the storage stability of said formulations. To this end, magnesium stearate is used in said formulations. One of the features of the inventive dry powder is that a high fine particle dosage or fine particle fraction can be maintained also under relatively extreme temperature and humidity conditions.
