Abstract

A method for manufacturing a plurality of pharmaceutical agent delivery patch devices includes: providing a supply web including an active layer containing a pharmaceutically active agent; and cutting the supply web to form cut lines through the active layer. The cut lines define in the active layer: a first active layer patch having a first peripheral edge formed by the cutting step; and a second active layer patch having a second peripheral edge formed by the cutting step. The first and second peripheral edges each include a corner portion. At least a first segment of the first peripheral edge and an opposing second segment of the second peripheral edge are formed by a shared one of the cut lines.

wherein the opioid drug is delivered to a mucosal surface in a unidirectional manner,

wherein the corner edge segments comprises one or more of a rounded corner edge segment, a circular corner edge segment or a diamond corner edge segment, and

wherein when dissolution testing is preformed comprising

positioning the pharmaceutical agent delivery patch in a dissolution basket comprising a cavity such that the patch is supported by a patch device holder and at least a portion of the patch is spaced apart from a sidewall and a bottom wall;
