This study will be performed at two sites and two-hundred and fifty (250) healthy male and female subjects will be included. Treatments comprise single doses of an experimental Nicotine Replacement Therapy (NRT) and Nicorette Freshfruit gum 4 mg, which are chewed during 30 minutes. All subjects will be given both treatments in a crossover setting. The length of the time interval separating treatment visits, and during which no NRT must be used, will be at least 36 hours.
The subjects will abstain from smoking from 8 pm the evening before until the end of each visit. The subjects will take the gums according to instructions from the study personnel. After chewing, used gums will be collected for nicotine analysis.
Electronic diaries will be used to collect data. Urges to smoke will be scored on a 100 mm visual analogue scale (VAS) before the start of treatment and during 5 hours thereafter. Subjects will also be monitored to capture any adverse events that may occur.
