Pharmacokinetic Study of 4 mg Nicotine Lozenge.
12 januari 2015 uppdaterad av: GlaxoSmithKline
A Randomized, Cross-Over, Single Dose Pharmacokinetic Study of 4mg Nicotine Lozenges.
This is a randomized, single center, open label, single dose, four way crossover study in fasted healthy male subjects to compare the pharmacokinetics of nicotine following administration of 3 prototype 4mg nicotine lozenge to an internationally marketed 4mg nicotine lozenge.
Blood samples will be drawn at pre-specified intervals for a total of 12 hours post dose in each treatment session and plasma samples analyzed for nicotine levels.
