Abstract

Foreliggende oppfinnelse tilveiebringer en tørrpulverinhalereringssammensetning som innbefatter. medikamentpartikler og en blanding av laktosepartikler med en VMD på mellom ca. 70 og 120 mikron og en diameter på mindre enn 250 mikron, hvor blandingen er kjennetegnet ved at opp til 96 vekt-% av laktosepartiklene er mindre enn 150 mikron i diameter, og hvori opp til 25 vekt-% av laktosepartiklene er mindre enn 5 mikron i diameter. Sammensetningene tilveiebringer en mer nøyaktig, enhetlig og. konsistent dispersjon når den for eksempel anvendes med en multidose tørrpulveirnhalerer.Også beskrevet er fremgangsmåter for anvendelse av sammensetningene ifølge oppfinnelsen.The present invention provides a dry powder inhalation composition which includes. drug particles and a mixture of lactose particles with a VMD of between approx. 70 and 120 microns and a diameter of less than 250 microns, wherein the mixture is characterized in that up to 96% by weight of the lactose particles are less than 150 microns in diameter, and in which up to 25% by weight of the lactose particles are less than 5 microns. in diameter. The compositions provide a more accurate, uniform and. consistent dispersion when used, for example, with a multidose dry powder inhaler. Also described are methods of using the compositions of the invention.
