Single-dose pharmacokinetics with two new oral nicotine replacement products and Nicorette® gum.
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.

Pharmacokinetic measurements
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∞)
Time frame: Baseline and during 8 hours after product administration
tmax
The time of occurrence of Cmax following product administration
Time frame: During 8 hours after start of product administration
Lamda z
The terminal nicotine elimination rate constant (λz)
Time frame: During 8 hours after start of product administration
Released amount of nicotine
The amount of nicotine released from gums during 30 minutes' chewing.
Time frame: After 30 minutes of chewing
