Brief summary
Single-dose pharmacokinetics with two new oral nicotine replacement products and Nicorette® gum.
Detailed description
The study is a single-dose, randomized, cross-over study. The investigational products will be given as single doses at separate visits. The product administrations comprise 30 minutes of chewing. Periods without NRT, lasting for at least 36 hours, will separate treatment visits. Before and after the start of product administration at each treatment visit, blood will be sampled for pharmacokinetic analyses, pre-dose, and during 8 hours after start of product administration. Used gums will be collected and analyzed to determine the amount of remaining nicotine. Subjects will also be monitored to capture any adverse events that may occur. Treatment labels will be concealed from subjects and study personnel.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pharmacokinetic measurements | Baseline and during 8 hours after product administration | Pharmacokinetic measurements including: * the maximum observed nicotine concentration in plasma (Cmax) * the area under the plasma concentration-vs.-time curve until the last measurable concentration (AUCt) * the area under the plasma concentration-vs.-time curve until infinity (AUC∞) |
Secondary
