A Bioequivalence Study of 21 Milligram (mg) Nicotine Transdermal Patches (NicoDerm CQ, GlaxoSmithKline [GSK] Dungarvan) Compared to the Current Marketed 21 mg Nicotine Transdermal Patches (NicoDerm CQ, Alza) in Healthy Adult Smokers

A Randomized, Open Label, Single Center, Single Dose, Two Period, Two Sequence Crossover Bioequivalence Study of 21 mg Nicotine Transdermal Patches (NicoDerm CQ, GSK Dungarvan) Compared to the Current Marketed 21 mg Nicotine Transdermal Patches (NicoDerm CQ, Alza) in Healthy Adult Smokers

The purpose of this study is to assess the bioequivalence of the 21mg nicotine transdermal patch from GSK Dungarvan (Test) compared to the 21mg nicotine transdermal patch currently manufactured by Alza (Reference).

This is a 2-arm, single center, single dose, open-label, randomized, two-sequence, two-period crossover, bioequivalence study in healthy adult smokers that have smoked more than 10 cigarettes per day for 1 year prior to initial dose. Carry-over effects will be avoided by a wash-out interval of at least 2 days (but no more than 4 days) from patch removal in the first treatment period to subsequent patch application. The study will consist of an ambulant screening day within 21 days prior first patch application.
