Evaluation of Nicotine Pharmacokinetics and Subjective Effects following Use of a Novel Nicotine Delivery System.

Introduction: Novel nicotine delivery systems represent an evolving part of the tobacco harm reduction strategy. The pharmacokinetic (PK) profile of nicotine delivered by P3L, a pulmonary nicotine delivery system, and its effects on smoking urges and craving relief in relation to Nicorette inhalator were evaluated.

Methods: This open-label, ascending nicotine levels study was conducted in 16 healthy smokers.

Effect of varenicline on individual nicotine withdrawal symptoms: a combined analysis of eight randomized, placebo-controlled trials.

Introduction: Concerns exist that varenicline may cause neuropsychiatric side effects. Some of these symptoms (e.g.

Efficacy of the nicotine inhaler in smoking reduction: A double-blind, randomized trial.

Many smokers are not ready to quit but are interested in changing their smoking behavior, particularly if such a change is associated with a reduction in health risk. The present study evaluated the efficacy of the nicotine inhaler in reducing smoking. Exploratory studies assessed whether reduction in smoking was associated with reduction in markers of disease risk.

A comparison of a nicotine sublingual tablet and placebo for smoking cessation.

This study assessed the efficacy and safety of a nicotine sublingual tablet in smoking cessation in a randomized, double-blind, placebo-controlled outpatient trial conducted between January 1996 and May 1997. Two hundred and forty-one adult smokers (> or = 10 cigarettes/day for at least 3 years) used nicotine 2-mg sublingual tablet (n = 120) or placebo (n = 121) for up to 6 months (a 3-month treatment period followed by a 3-month tapering period). Subjects who scored <7 on the Fagerström Tolerance Questionnaire used 1 tablet/h (up to maximum of 20/day), whereas subjects who scored (7 used 2 tablets/h (up to maximum of 40/day).
