• Interventions: Drug: Nicotine Bitartrate Lozenge 4mg; Drug: Nicotine Polacrilex 4Mg Lozenge

• Registration Number: NCT03087786
• Lead Sponsor: Niconovum USA

Brief Summary

To study the oral mucosal effects in adult smokers associated with the use of two Nicotine Lozenge formulations.

Detailed Description

To assess the oral mucosal health associated with 3 weeks of use of test product, Nicotine Bitartrate 4 mg mint lozenge, relative to a reference product, Nicorette® \[Nicotine Polacrilex\] 4 mg mint lozenge, in healthy adult smokers motivated to quit smoking.

To evaluate the safety and tolerability of Nicotine Bitartrate 4 mg mint lozenge and Nicorette® \[Nicotine Polacrilex\] 4 mg mint lozenge in this subject population.
