Abstract
An inhaler for use with a dry powder pharmaceutical formulation, including: a chamber containing the dry powder formulation, a valve disposed in series with the chamber for regulating air flow through the chamber, and a bypass coupled around the combination of the chamber and the valve, where the valve and bypass cooperate for ensuring that the air flow is at least essentially fixed or kept constant or at a minimum accepted or desired or required flow rate through the chamber, and for varying air flow restriction through the inhaler with flow rate, or for keeping the air flow restriction generally constant.
