  • Patent number: 11504342
    Abstract: A pharmaceutical active-containing transmucosal delivery device comprises a polymer film comprising a polymer matrix, wherein the film has a pH in the range of about 4 to about 9, and a pharmaceutical active composition disposed on a surface of the polymer film. The composition comprises at least one pharmaceutical active ingredient in the form of particles, and wherein the particles have an average particle size of about 100 nm to about 5 microns, an anti-crystallization agent, and a pH adjusting agent, wherein the concentration of the pharmaceutical active ingredient is at least 20% w/w relative to the total weight of the pharmaceutical active composition. The delivery device exhibits a residence time in the mouth of a subject ranging from about 5 minutes to about 30 minutes and is substantially mucoadhesive to a mucosa surface when placed sublingually under the tongue or placed buccally at the inner lining of the cheek.

  • Publication number: 20220184841
    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.
