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.
