[TABAC] sevrage tabagique:méthode de sevrage:méthode individuelle:approche pharmacologique:varéniclineIndex. décimale : TA 6.2.3.1.4 Autres substituts nicotiniques Résumé : Varenicline is a novel and selective α4β2 nicotinic acetylcholine receptor partial agonist developed for smoking cessation. The primary objectives of this double-blind, placebo-controlled, dose-escalation study were to determine the pharmacokinetics, safety, and tolerability of multiple oral doses of varenicline given as tablets once (1 mg, 2 mg, and 3 mg) or twice (1 mg) daily to healthy adult smokers. Within each dose level, 8 subjects were randomized to varenicline and 4 subjects to placebo. Varenicline was well tolerated at doses up to and including 2 mg daily. Dose-proportional increases in maximum observed plasma concentrations and area under the plasma concentration-time curve from time zero to the end of the dosing interval values were observed between the 1-mg and 2-mg daily doses of varenicline. Once- and twice-daily dosing resulted, on average, in an approximate 2- and 3-fold increase in varenicline systemic exposure, respectively, compared with single dose. There was no evidence of concentration- or time-dependent changes in the pharmacokinetics of varenicline upon repeat dosing.

The body-weight effect on varenicline pharmacokinetics, which resulted in higher exposure in individuals of smaller body size (<::55 kg), was adequately offset by administration of half the varenicline dose recommended in adults. Varenicline was generally well tolerated during the 14-day treatment period.

[TABAC] sevrage tabagique:méthode de sevrage:méthode individuelle:approche pharmacologique:varéniclineIndex. décimale : TA 6.2.3.1.4 Autres substituts nicotiniques Résumé : Varenicline is a novel and selective alpha4beta2 nicotinic receptor partial agonist that is under development for smoking cessation. The primary objectives of this double-blind, placebo-controlled, single-dose, dose-escalation study were to determine the clinical pharmacology of single doses of varenicline in healthy smokers and nonsmokers under fed and fasted conditions and to determine the clinical pharmacology of varenicline administered in the morning and in the evening to smokers. Within each subject group, 4 subjects were randomized to varenicline and 2 subjects to placebo. Subjects received one single oral administration of varenicline or placebo: 6 doses (0.01, 0.03, 0.1, 0.3, 1.0, and 3.0 mg) were investigated in nonsmokers and 7 doses in smokers (0.01, 0.03, 0.1, 0.3, 1.0, 3.0, and 10.0 mg). Varenicline was well tolerated after single doses up to 3.0 mg in smokers and 1.0 mg in nonsmokers. Nausea and vomiting at doses above 3.0 mg in smokers and 1.0 mg in nonsmokers were dose limiting. Systemic exposure to varenicline and pharmacokinetic variability were similar between smokers and nonsmokers. Coadministration with food, smoking restriction, and time-of-day dosing did not affect the pharmacokinetics of varenicline.

[TABAC] sevrage tabagique:méthode de sevrage:méthode individuelle:approche pharmacologique:varéniclineIndex. décimale : TA 6.2.3.1.4 Autres substituts nicotiniques Résumé : Smoking is a significant public health problem, and existing treatments have demonstrated only moderate efficacy in assisting smokers to quit. Varenicline, recently approved by the U.S. Food and Drug Administration and the European Agency for the Evaluation of Medicinal Products as an aid to smoking cessation treatment, has a novel mechanism of action, targeting the specific nicotinic acetylcholine receptor (nAChR) associated with nicotine-induced behaviors (alpha4beta2 nAChR). It has both agonistic and antagonistic properties that together are believed to account for reduction of craving and withdrawal as well as blocking the rewarding effects of smoking. The clinical efficacy and tolerability of varenicline has been demonstrated in phase III clinical trials involving more than 2,000 cigarette smokers. At the end of the treatment period in two 12-week, multicenter, randomized, double-blind, placebo-controlled studies, patients receiving varenicline (1 mg twice daily) experienced an increase in the odds of quitting smoking by nearly fourfold compared with those receiving placebo, and almost twofold compared with the odds for patients receiving 150 mg bupropion SR (sustained release) twice daily. In these two trials where patients were randomized to either varenicline or bupropion, the efficacy of varenicline was consistently superior at 12 weeks; this result sustained significance at 24 weeks in both studies and up to 52 weeks in one study. Nausea, a common adverse event reported in clinical trials, led to few treatment discontinuations. Its targeted mechanism of action, superior efficacy and excellent tolerability make varenicline a welcome and useful addition to the therapeutic options for smoking cessation.
