Subjective effects of an initial dose of nicotine nasal spray predict treatment outcome.
BACKGROUND
Nicotine nasal spray (NS) is recommended as one of five first-line smoking cessation products. A clinically convenient tool to identify smokers most likely to benefit from NS could assist healthcare practitioners in selecting the optimal treatment for individual patients.


OBJECTIVE
To evaluate whether the subjective effects of an initial pre-treatment dose of NS predict 6 month abstinence rates following NS treatment for tobacco dependence.


METHODS
One hundred and seventy-five smokers received an initial 1 mg pre-treatment dose of NS and completed a new measure of NS subjective effects (initial spray experience, ISE). This measure, together with demographic and smoking history variables, was examined as a predictor of 6-month point-prevalence (biochemically verified) abstinence rates.


RESULTS
Factor analysis revealed positive and negative effects subscales of the ISE. Smokers with higher ratings of positive effects from the pre-treatment NS dose were significantly more likely to be abstinent at 6-month follow-up. These effects were partially mediated by reduction in urge to smoke.


CONCLUSIONS
Pending additional validation in human laboratory and clinical studies, assessment of the acute positive subjective effects of initial NS delivery may be an efficient way to predict who will be successful with NS treatment for tobacco dependence.
