Abstract: A fast-dissolving film to be placed in the oral cavity of a person includes melatonin, or melatonin analog, with or without menthol, or menthol analog, that can be absorbed through the oral mucosa directly into the person's bloodstream. The film is thin and made from a low-moisture, non-tacky material that becomes dissolved when hydrated and that is sized so that the substrate can be placed in oral cavities of persons. From 0.3 mg to 10 mg melatonin, or a melatonin analog, and, optionally, menthol, or a menthol analog, are added to the substrate, which is then packaged in a flat, sealed container that can be unobtrusively placed into a pocket carried by the person, thereby making the container readily accessible to the person. In use, the film is removed from the container and placed into the person's oral cavity so that it contacts a mucosal membrane in the oral cavity of the person to thereby hydrate the substrate.

Abstract: A fast-dissolving film to be placed in the oral cavity of a person includes nicotine, or nicotine analog, with or without menthol, or menthol analog, that can be absorbed through the oral mucosa directly into the person's bloodstream for the purpose of reducing a temporary craving for nicotine during periods when smoking is not possible, or for therapeutic purposes, the film being thin and made from a low-moisture, non-tacky material that becomes dissolved when hydrated and that is sized so that the substrate can be placed in oral cavities of persons. From 0.1 mg to 10 mg nicotine, or a nicotine analog, and, optionally, menthol, or a menthol analog, are added to the substrate, which is then packaged in a flat, sealed container that can be unobtrusively placed into a pocket carried by the smoker, thereby making the container readily accessible to the smoker.
