Abstract
A method for forming and packaging an iontophoretic patch in an inert atmosphere to provide increased shelf-life. The method includes a number of sub-assemblies for forming a well in a laminate material, forming the reservoir and dosing the reservoir, sealing the laminate material and another laminate material together to form a continuous web from which the individual patches are cut. In addition, the patch can be subsequently enclosed in an individual package. In this way, the patch and/or package provides a commercially suitable shelf-life to the drug-filled patch stored therein.

A method of forming and packaging an iontophoretic patch including a drug filled reservoir comprising the steps of:
- forming a well in a first laminate material;
- placing a reservoir material in said well and placing at least a portion of a dose of medication therein to fill said reservoir material;
- placing a second laminate material over said well;
- sealing said laminate materials together to form a continuous web, so that a chamber is formed therebetween having an inert gas contained in said chamber;
- and
- cutting an individual patch from said web.
A method of forming and packaging an iontophoretic patch including a drug filled reservoir comprising the steps of:
- placing a reservoir material on a first laminate material and dosing said reservoir material with at least a portion of a medicament to at least partially fill said reservoir material;
- sandwiching said reservoir material between said first laminate material and a second laminate material with said reservoir material positioned therebetween;
- sealing said laminate materials together to form a continuous web, so that a chamber is formed therebetween having an inert gas contained in said chamber;
- and
- cutting an individual patch from said web.
