<P>PROBLEM TO BE SOLVED: To provide a dry powder composition comprising glycopyrrolate which exhibits greater stability than conventional dry powder glycopyrrolate formulations, and to provide a method for consistently and reliably preparing a stable dry powder composition comprising glycopyrrolate. <P>SOLUTION: The dry powder composition includes the glycopyrrolate which has been made particulate. The dry powder composition in which the glycopyrrolate is made to be particulate, thereby humidity absorbing nature can be reduced and powder dispersion nature can be raised, is stable for at least one year, more preferably at least two years, and most preferably for at least three years under the ordinary condition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
