The first product, the Inhaler, consists of an inhaler consisting of a mouthpiece and a plastic cartridge delivering nicotine from a porous plug. The cartridge is inserted into the mouthpiece prior to use. Nicotine is released when air is inhaled through the inhaler. The inhaler is sold by prescription-only and taken under physician’s guidance.
The second product, the Nasal Spray, is also indicated as an aid to smoking cessation for the relief of nicotine withdrawal symptoms. The product consists of an aqueous solution of nicotine, the active ingredient, as well as a nasal spray delivery system which administers a metered spray of the nicotine solution to the nasal mucosa. The Inhaler, like the Nasal Spray, is sold by prescription-only and taken under a physician’s guidance. The user receives gradually decreasing amounts of nicotine to overcome nicotine dependence and enable the user to quit smoking.
