Comparison of Pharmacokinetic Profiles of 3 New Nicotine Gum Formulations With a Reference Gum

A Pilot, Open Label, Randomised, Single Dose, Four-Period, Four-Treatment, Four-Sequence, Four Way Crossover Comparative Pharmacokinetic Study of Three Different 4 mg Nicotine Chewing Gum Test Formulations of Fertin Pharma A/S, Denmark With Nicorette Freshmint 4 mg Medicated Chewing Gum of McNeil Denmark ApS as Reference Formulation in Healthy, Adult, Human Smokers Under Fasting Conditions
