Clinical Context

Nicotine replacement therapy (NRT) is described by the FDA as providing the body with smaller doses of nicotine over time without exposing users to the toxic chemicals in cigarette smoke; NRT is intended to be used in conjunction with a behavioral program and has been found to increase the success of smoking cessation [2]. Over-the-counter NRTs approved for sale to people age 18 and older include skin patches, chewing gum, and lozenges, while prescription nicotine products include nicotine spray and nicotine inhaler [2]. The FDA consumer material also lists two FDA-approved, non-nicotine, prescription tablet products for smoking cessation: varenicline tartrate and bupropion hydrochloride, and states the FDA evaluated these drugs and found that the benefits outweigh the risks [2]. The FDA finalized guidance for developing NRT drug products in May 2023 (Docket FDA-2019-D-0297) to assist sponsors in clinical development for smoking cessation and related indications [3].
