Effect of nicotine mouth spray on urges to vape: A randomized, placebo-controlled, pharmacodynamic clinical trial in exclusive e-cigarette users.
Aims: To determine whether nicotine mouth spray provides rapid and prolonged relief of urges to vape and measure the steady-state plasma nicotine levels during vaping and ad libitum mouth spray usage in e-cigarette users.
Setting: Single site at Hammersmith Medicines Research Ltd (HMR), London, UK.
Participants: 216 (25.9% females, average age 27.6 ± 7.63 [standard deviation, SD]) exclusive vapers who used their e-cigarette within 30 minutes of waking up and had vaped about 2 years on average.
Interventions: Two sprays of 1 mg nicotine mouth spray (Nicorette QuickMist Freshmint, n = 109), or placebo (identical in appearance and presentation, n = 107).
Measurements: Urge to vape was rated on a 100 mm visual analogue scale before and repeatedly for 2 hours after administration. The primary outcome measured average change from baseline in urges to vape ratings during the first hour.
Findings: Nicotine mouth spray achieved statistically significantly greater reductions in urges to vape than placebo from the first assessment point at 30 seconds to 1 hour, when the estimated mean treatment difference was 11.90 mm (95% confidence interval [CI] = 6.86-16.95, P < 0.001). The integrated urge to vape over 11 hours ad libitum usage showed a statistically significant benefit compared with placebo (2.00 [0.88 SD] vs 2.51 [0.84 SD], P < 0.001). Mean steady-state plasma nicotine concentrations were lower after nicotine mouth spray usage compared with vaping (6.22 [4.70 SD] ng/ml vs 9.91 [7.59 SD] ng/ml, respectively). Adverse events were more commonly reported in the nicotine mouth spray group and were mostly mild.
Conclusions: Among regular e-cigarette users, nicotine mouth spray provided statistically significant and fast relief of urges to vape one hour after dosing. Nicotine mouth spray showed statistically significant reductions in urges to vape as soon as 30 seconds and up to 2 hours after dosing compared with placebo, and nicotine mouth spray was well-tolerated and safe.
期刊介绍：
Addiction publishes peer-reviewed research reports on pharmacological and behavioural addictions, bringing together research conducted within many different disciplines.
Its goal is to serve international and interdisciplinary scientific and clinical communication, to strengthen links between science and policy, and to stimulate and enhance the quality of debate. We seek submissions that are not only technically competent but are also original and contain information or ideas of fresh interest to our international readership. We seek to serve low- and middle-income (LAMI) countries as well as more economically developed countries.
Addiction’s scope spans human experimental, epidemiological, social science, historical, clinical and policy research relating to addiction, primarily but not exclusively in the areas of psychoactive substance use and/or gambling. In addition to original research, the journal features editorials, commentaries, reviews, letters, and book reviews.
