Pharmacokinetic Study of 4 mg Nicotine Lozenge.
2015年1月12日 更新者：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.

Area Under the Curve From Time 0 to t, AUC (0-t)
大体时间：Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|
Area under the plasma concentration time curve from zero and extrapolated to the time of last quantifiable sample was determined from plasma concentration time profile of nicotine.
AUC(0 -t) was based on the baseline adjusted nicotine plasma concentration data.
|
Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing

Maximum Plasma Concentration (Cmax)
大体时间：Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|
Maximum plasma nicotine concentration was determined from plasma-concentration time profiles.
Cmax was based on the baseline adjusted nicotine plasma concentration data.
|
Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
