Abstract (en)
[origin: CA2505126A1] An adherent, soluble oral patch for delivering topical medication in the mou th including a hydrophilic polymer that is liquid at human mouth temperatures. Preferably, the hydrophilic polymer gels to a solid at temperatures just bel ow human mouth temperatures, preferably collagen such as animal gelatin. The structure of the oral patch is formed with a porous network that remains sol id at human mouth temperatures and slowly dissolves in saliva. In some embodiments, the network is elasto-plastic and in some cases it is hydrophilic. The hydrophilic polymer is located within pores of the network, along with a desired medication. The oral patch is formed by mixing and hydrating the ingredients, bringing them to above an activation temperature below boiling, and cooling them to form a gel. The hot mixture may be poured into molds, including a flat sheet, and the mold may also serve as packaging for delivery. The packaging may comprise a germ barrier moisture passing fil m which allows the oral patch to dry out or become re-hydrated without growing mold.
