简要总结
A comparison of three products for oral nicotine replacement with respect to pharmacokinetics after single-dose of nicotine.
详细描述
This study compares a new oral Nicotine Replacement Therapy (NRT) product with NiQuitin™ lozenge 4 mg and Nicorette®gum 4 mg, after 12 hours of nicotine abstinence, with respect to nicotine pharmacokinetics, during 12 hours after start of administration. Single doses of each treatment are given once in the morning during five separate treatment visits scheduled in a crossover setting with randomized treatment sequences. The study will include 45 healthy smokers between 18-50 years, who have been smoking at least 15 cigarettes daily during at least one year preceding inclusion. Subjects and study personnel will be aware of which treatment is administered at a given visit.

结局指标
主要结局
Maximum Plasma Concentration
时间窗: During 12 hours after start of administration
Cmax, which is the maximum (peak) concentration (amount of drug) measurable in blood plasma after a dose is administered measured in nanograms/milliliter (ng/ml)
Bioavailability
时间窗: 12 hours
A measure of how much of the drug reaches a person's bloodstream within a given period of time for the body to use. The extent of product bioavailability is estimated by the area under the blood concentration vs time curve. The area under the curve (AUC) is calculated by plotting the drug's blood levels on a graph at different times during the set period to form a curve. The area under this curve reflects the amount of drug exposure in the set time period, calculated as hour\*nanograms/milliliter (h\*ng/ml).
次要结局
- Nicotine Plasma Concentration(During 10 minutes after start of administration)
- Time of Maximum Concentration(During 12 hours after start of administration)
- Terminal Elimination Rate Constant(During 12 hours after start of administration)
- Released Nicotine(After 30 minutes' chewing)
