Pharmacokinetics With Two New Oral Nicotine Replacement Products and Nicorette® Gum

Study Overview
=================
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.
