Abstract
Mouthpieces for particulate inhalers typically have either stationary particle deflectors or rotatable devices for changing the flow of particulate material through the mouthpiece. However, these mouthpieces do not prevent the build up of particulate drug on the walls of the mouthpiece. Thus, there is provided a mouthpiece ( ) for use in an inhaler for particulate medicament, the mouthpiece having an inlet ( ) and an outlet ( ) for particulate medicament, a helical member ( ) disposed between the inlet and the outlet for, in use, imparting a rotational movement to an air flow which is drawn through the mouthpiece and in which medicament is entrained, wherein the helical member ( ) is, in use, axially movable between a first position and a second position such that it restricts the build up of medicament on the inside of the mouthpiece ( ).
