Objective To evaluate the efficacy of using a nicotine patch for 5 months with a nicotine nasal spray for 1 year.
Setting Reykjavik health centre.
Subjects 237 smokers aged 22-66 years living in or around Reykjavik.
Interventions Nicotine patch for 5 months with nicotine nasal spray for 1 year (n=118) or nicotine patch with placebo spray. (n=119).
Treatment with patches included 16 mg of nicotine for 3 months, 10 mg for the fourth month, and 5 mg for the fifth month, whereas nicotine in the nasal spray was available for up to 1 year.
Both groups received supportive treatment.
Main outcome measure Sustained abstinence from smoking.
Results The log rank test for 6 years (X2=8.5, P=0.004) shows a significant association between abstinence from smoking and type of treatment Sustained abstinence rates for the patch and nasal spray group and patch only group were 51% v 35% after 6 weeks (P=0.011 (X2), 95% confidence interval 1.17%) to 3.32%), 37%1 v 25% after 3 months (P=0.045,1.01% to 3.08%), 31% v 16% after 6 months (P=0.005,1.27% to 4.50%), 27% v 11% after 12 months (P=0.001,1.50% to 6.14%), and 16% v 9% after 6 years (P=0.077,0.93% to 4.72%). Conclusions Short and long term abstinence rates show that the combination of using a nicotine patch for 5 months with a nicotine nasal spray for 1 year is a more effective method of stopping smoking than using a patch only.
