Abstract
A child-resistant blister pack for fragile single-dosage forms, e.g. a fast-dissolving dosage form ((FDDF) is disclosed. Limited entry points are provided, and completion of a sequence of steps is necessary to access the dosage forms within the depressions. A blister film sheet with depressions for receiving dosage forms is sealed with a lidding sheet and perforated to provide lines of weakness to define single dosage units with a depression containing a dosage form in each dosage unit. Single- or double-entry embodiments are disclosed, allowing access from one or two points on the blister sheet. After tearing along the perforations, a single dosage unit is separated from the blister pack. The user may then access the single-dosage form in the associated single-dosage unit. In a first embodiment, the dosage unit has a tear strip for exposing an unsealed corner, thereby allowing access to the dosage form within by grasping the edge and peeling it off the blister film sheet. In a second embodiment, the unsealed corner is exposed upon separation of the dosage unit from the blister film sheet.
