Cotinine is the major proximate metabolite of nicotine. The aims of our study were to assess the pharmacokinetics of oral cotinine comparing the use of saliva and plasma concentrations, and to characterize the subjective and cardiovascular effects of oral cotinine in nonsmokers. The clearance and half-life of cotinine measured using plasma or saliva concentrations were similar. There was no change in heart rate or blood pressure, and no differences in subjective response with cotinine compared to placebo. We conclude that administration of oral cotinine with measurement in saliva samples is easy, safe, and provides an accurate estimate of systemic clearance and half-life of cotinine.
