METHOD FOR FORMING AND PACKAGING IONTOPHORETIC DRUG DELIVERY PATCHES AND THE LIKE TO INCREASE STABILITY AND SHELF-LIFE

摘要

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.
