ABSTRACT:
The present invention relates to an improvement of the mouthpiece of a dry powder inhalation device wherein the medicament is packed in the blisters of single dose blister strips. According to the invention a portion of the air which enters the mouthpiece does not pass through the powder containing blister, but follows an alternative path through the mouthpiece, enabling therefore the modification of the resistance of the device in a simple and cost effective manner.
