A
system intended to be employed for therapeutic purposes incorporates an
active ingredient (e.g., a source of
nicotine). Representative forms of
nicotine include
free base (e.g., as a mixture of
nicotine and
microcrystalline cellulose), a nicotine salt (e.g., as nicotine bitartrate) and nicotine polacrilex. The
system preferably comprises a lozenge incorporating the
active ingredient, adapted toprovide
oral administration of nicotine. The lozenge is in contact with a substrate (e.g., hollow tube) that can be manipulated within the mouth of the user (e.g., the hollow tube can be drawn upon tosimulate the
inhalation of
cigarette smoke). As such, the
active ingredient is administered and the user is able to experience certain other physiological sensations. The composition is useful for treatment of
central nervous system conditions, diseases, and disorders, and can be used as a
nicotine replacement therapy. The
system comprising: a substrate portion (35) having an upstream end and a downstream end, the upstream end allowing for passage of drawn
atmospheric air into the substrate and the downstream end adapted for positioning into a user's mouth for draw upon the substrate and
inhalation of
atmospheric air by the user, a lozenge portion (20) incorporating a source of active ingredient in a pharmaceutically acceptable form, the lozenge portion providing for oral
ingestion of theactive ingredient, the lozenge portion and the substrate portion being physically separate from one another but in contact with each other, the lozenge being positioned at the downstream end of the substrate, and the lozenge and substrate portions being positioned so that the lozenge portion and a portion of the substrate portion can be located in the user's mouth during use, to provide for delivery of active ingredient from the lozenge and drawn air through the substrate.
