PATCH DEVICES, METHODS AND APPARATUS FOR FORMING, AND TESTING PHARMACEUTICAL AGENT DELIVERY PATCH DEVICES
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.

immersing the dissolution basket and the patch therein in a dissolution fluid; and
moving the dissolution basket with the patch device therein in the dissolution fluid to generate a flow of the dissolution fluid across the patch device,
wherein the pharmaceutical agent delivery patch comprising buprenorphine alone, the buprenorphine dissolves between about 54% to about 62% in 10 minutes.
9 . The pharmaceutical agent delivery patch of claim 8 , wherein the buprenorphine dissolves between about 54 and about 62% in 10 minutes and between about 95 and about 100% in about 60 minutes.
10 . The pharmaceutical agent delivery patch of claim 9 , wherein the buprenorphine dissolves between about 10% and about 20% slower in the first 10 to about 30 minutes.
11 . The pharmaceutical agent delivery patch of claim 9 , wherein the buprenorphine dissolves between about one or more of 48.6% to about 55.8% in about 10 minutes; 74.7% to about 80.1% in about 20 minutes; 81.9% to about 88.2% in about 30 minutes, 84.6% to about 90% in about 40 minutes, or 5.5% to about 100% in about 50 minutes.

providing a supply web comprising an active layer comprising a pharmaceutically active agent; and
cutting the supply web to form cut lines through the active layer, wherein the cut lines define in the active layer:
a first active layer having a first peripheral edge formed by the cutting step; and
a second active layer having a second peripheral edge formed by the cutting step;
wherein the first and second peripheral edges each include a corner edge segment; and
wherein 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.
17 . The method of claim 16 , wherein the corner edge segment comprise one or more of a rounded corner edge segment, a circular corner edge segment or a diamond corner edge segment.
18 .- 21 . (canceled)
22 . The method of claim 16 , wherein:
the cut lines define waste portions in the active layer; and
the method includes separating the first and second active layers from the waste portions.
23 . The method of claim 22 , wherein the waste portions are one or more of circular, oval, diamond, star or square shaped.
24 .- 29 . (canceled)
30 . The method of claim 16 , wherein the step of cutting the supply web comprises cutting through the active layer to form the cut lines using a punch cutting head.
31 . The method of claim 16 , wherein:
the supply web comprises a support web and the active layer is releasably bonded to the support web; and
the step of cutting the supply web comprises forming the cut lines fully through the active layer down to, but not through, the support web.
