Brief summary
A comparison of three products for oral nicotine replacement with respect to pharmacokinetics after multiple-doses of nicotine.
Detailed description
This study compares a new oral Nicotine Replacement Therapy (NRT) product with NiQuitin™ lozenge 4 mg and Nicorette®gum 4 mg, after 12 hours of nicotine abstinence, with respect to steady-state nicotine pharmacokinetics, during 12 hours after start of the first administration. Multiple doses of each treatment are given once hourly during five separate treatment visits scheduled in a crossover setting with randomized treatment sequences. The study will include 40 healthy smokers between 18-50 years, who have been smoking at least 20 cigarettes daily during at least one year preceding inclusion. Subjects and study personnel will be aware of which treatment is administered at a given visit.
Interventions
Oral Nicotine either self-administered or provided by study personnel within 12 hours
Nicotine lozenge marketed as NiQuitin™ 4 mg hourly within 12 hours
Nicotine gum marketed as Nicorette® 4 mg hourly within 12 hours

This was a five-arm cross-over trial, with subjects randomized to the order they received the different treatments and with analysis performed on valid pharmacokinetic data. Therefore, Number of Participants Analyzed in each arm represents the same subjects, and the total is not consistent with numbers provided in the participant flow module.
