Multidrug and toxin extrusion (MATE) 1 and MATE2-K, H(+)/organic cation antiporters, are located at the brush-border membrane of renal proximal tubules. The present study aimed to clarify the role of MATE transporters in tubular secretion of varenicline. Varenicline at a dose of 5 mg/kg was administered to wild-type and Mate1-knockout mice via the jugular vein, and its uptake was measured by hi...
Late-life onset manic attacks generally occur secondary to general medical conditions or drug use. Varenicline is an α4β2 nicotinic acetylcholine receptor partial agonist, used for the cessation of smoking. In this case report, we present a 67-year-old male patient with a new-onset manic episode following varenicline treatment. The patient's manic symptoms started on the seventh day of varenicl...
Since a substantial proportion of smokers have comorbid mood disorders, the smoking cessation aid varenicline might occasionally be prescribed to patients who are simultaneously treated with antidepressants. Given that varenicline is a selective nicotinic acetylcholine receptor partial agonist and not a substrate or inhibitor of drug metabolizing enzymes, pharmacokinetic interactions with vario...
The data shows attentional function, impulsivity, motivation, motor function, and motor activity in rats treated with varenicline, a stop-smoking aid. The data also shows these parameters in rats treated with varenicline after acute/chronic nicotine administration. Our interpretation and discussion of these data were described in the article "Varenicline Provokes Impulsive Action by Stimulating...
INTRODUCTION Varenicline is widely used for smoking cessation. It has shown efficacy over placebo and bupropion in manufacturer-sponsored trials. Those with mental illness were excluded from these trials. There are case reports of exacerbation of mental illness and development of psychiatric symptoms with varenicline use. CASE PRESENTATION A 61-year-old male Caucasian being treated for post-t...
Smoking is the leading preventable cause of morbidity and mortality in the US, and decreasing smoking prevalence is a public health priority. Patients achieve the greatest success when quit attempts involve behavioral therapy combined with pharmacotherapy. Varenicline is the most recent addition to the pharmacotherapeutic armamentarium for the treatment of tobacco dependence. Varenicline is eff...
OBJECTIVES A recent trial showed the clinical benefit of retreatment with varenicline in subjects failing on the initial treatment, or relapsing after initial success. The objective of this study was to evaluate the cost-effectiveness of retreatment with varenicline compared with other smoking cessation interventions. METHODS A published Markov model was adapted to compare one quit attempt of...
BACKGROUND Smoking remains a serious public health concern. Pharmacotherapy for smoking cessation, including bupropion and varenicline, are proven means to increase quit rates. Post-marketing reports describing suicidal behaviours have raised concerns about the safety of varenicline. However, whether varenicline imparts a higher risk of suicide relative to bupropion remains uncertain. METHODS...
Recently, the smoking cessation therapeutic varenicline, a nicotinic acetylcholine receptor (nAChR) partial agonist, has been shown to reduce alcohol consumption. However, the mechanism and nAChR subtype(s) involved are unknown. Here we demonstrate that varenicline and alcohol exposure, either alone or in combination, selectively activates dopaminergic (DAergic) neurons within the posterior, bu...
INTRODUCTION Current smoking cessation guidelines recommend setting a quit date prior to starting pharmacotherapy. However, providing flexibility in the date of quitting may be more acceptable to some smokers. The objective of this study was to compare varenicline 1 mg twice daily (b.i.d.) with placebo in subjects using a flexible quit date paradigm after starting medication. METHODS In this ...
