Primary outcomePrimary: Area Under the Plasma Concentration Versus Time Curve From Time Zero to Time t [AUC(0-t)] — 18.84; 20.71; 34.71; 33.68 nanogram (ng).hour (hr)/millilitre (mL)
Summary
To compare the bio equivalence of new nicotine lozenge formulation with the reference nicotine lozenge so as to deliver the same nicotine blood profile.
