The invention relates to a method for treating overactive bladders and a device for storing and administering non-occluded oxybutynin topical compositions.

Method for treating overactive bladders and a device for storage and administration of topical oxybutynin compositions

A peelable pouch comprises a substantially flat enclosure formed by first and second opposing flexible plies. A seat extends along at least a portion of a perimeter of the opposing plies. A flat, flexible transdermal patch is disposed in the enclosure and includes a bioactive agent dissolved in a layer of adhesive. A release liner is removably attached over the layer of adhesive, with the patch and the release liner together being sufficiently resilient so as to generate a spring force when displaced out of the flat configuration. The first and the second plies each being separable along the seal and displaceable out of the flat configuration. The spring force generated by the patch and the release liner being sufficient to overcome an adhesive force created by the adhesive between the patch and one of the plies.
