Amorphous drug transdermal systems, manufacturing methods, and stabilization

摘要

The present invention refers to a transdermal delivery device comprising a backing layer, an adhesive matrix layer comprising a supersaturated concentration of an active agent substantially in amorphous form within the adhesive matrix, and a release liner. The present invention also refers to a method of preparing an adhesive matrix containing at least one supersaturated active agent substantially in amorphous form. Further, the present invention refers to a method to stabilize and a method to reestablish the meta-stable amorphous-drug transdermal system during its manufacturing, storing, shipping and handling process.
