A dry-powder inhalation device including a casing having at least one push button located on an external portion thereof, the push button including at least one pin structure, an air inlet located at a first terminus of the casing a powder delivery port located at a second terminus of the casing and is positioned distal to the air inlet and an elongated support panel located within an interior of the casing and being fitted within the casing so as to partially rotate therein about a single axis. The support panel has at least one compartment containing dry-powder located proximal to the first terminus, and the at least one pin structure is located proximal to the air inlet and arranged above the dry-powder compartment. The compartment with a dry-powder includes a blister structure encasing the dry-powder, whereby airflow through the device causes the elongated support panel to partially rotate repeatedly within the casing, thereby striking the plurality of needle-like structures and releasing the dry-powder in the airflow.
