Embodiments of an inhaler device include a housing, a withdrawing assembly disposed within the housing for facilitating withdrawal of medicament from a target blister of a blister strip, the withdrawing assembly including an opening element adapted for opening the target blister of the blister strip while the target blister is positioned in the withdrawing assembly, and a dispensing element adapted for directing the withdrawn medicament toward the exterior of the inhaler device. A blister track is disposed within the housing for guiding each blister of the blister strip to the withdrawing assembly in succession, an advancing mechanism for advancing the blister strip by a predetermined distance each time the advancing mechanism is engaged, and an engaging element for engaging the advancing mechanism to advance the blister strip. The blister track includes a primary coil structure, a secondary coil structure, and a tertiary coil structure.
