Patent ID: 8871243

Claim:
A dry oral film that is disintegrable in saliva and that has mucoadhesivity to the oral mucosa consisting of: a) at least 45 weight percent (based on the total weight of the dry film) of at least one water soluble film-forming polymer selected from the group consisting of cellulose, cellulose derivatives, polyalkylene oxides, polyalkylene glycols, synthetically or naturally occurring gums, acrylic acid polymers, acrylic acid copolymers, methacrylic acid polymers, methacrylic acid copolymers, polyacrylamides, carrageanan, pullulan, polyvinyl pyrrolidone, polyvinyl alcohol, alginic acid, polyethylene glycol-polyvinyl alcohol copolymers, salts of alginic acid, and carboxyvinyl polymers; b) a nicotine active; and, optionally, c) one or more compounds selected from the group consisting of taste-modifying agents, bioadhesive agents, coloring agents, stabilizing agents, inert fillers, emulsifying agents, permeation enhancers, plasticizers, and preservatives; wherein component (c) is not a pH adjusting agent or buffering agent, and wherein the film maintains at least partial integrity and active agent release capability after in vitro exposure to artificial human saliva solution for at least 15 minutes.
