Dry powder for inhalation
摘要:
PROBLEM TO BE SOLVED: To improve the moisture resistance of dry powder formulations for inhalation and to improve the storage stability of the formulations.SOLUTION: For improving the moisture resistance of dry powder formulations for inhalation and improving the storage stability of the formulations, the formulations contain a phamaceutically not effective carrier of not-inhalable particle size and a finely divided phamaceutically effective substance of inhalable particle size. For the improvement, magnesium stearate is used in the formulations. One of the features of the inventive dry powder is that a high fine particle dosage or fine particle fraction can be maintained under relatively extreme temperature and humidity conditions.
