[The effect of transdermal nicotine patches in smoking cessation. A randomized trial in pharmacy customers in Denmark].
The aim of the study was to examine the effect of 24-hour nicotine patches in smoking cessation among over-the-counter customers in Denmark based on a randomized, double-blind, placebo-controlled trial. Participants were consecutive customers to whom nicotine patches were offered free of charge and as the only treatment. Forty-two pharmacies in the areas of Aarhus and Copenhagen in Denmark participated in the trial, and 522 customers who smoked 10 or more cigarettes per day were randomized to either nicotine or placebo patches from January to March 1994. Twenty-four-hour patches were offered for a three-month period. Those smoking 20 or more cigarettes per day started on 21 mg/day patches. Customers who smoked less started on 14 mg/day patches and all the participants were gradually reduced to 7 mg/day patches during the study period. Smoking behaviour and compliance were recorded by means of self-administered question-naires and telephone interviews. Smoking status was recorded following each four-week treatment period, and 26 weeks after inclusion. There was a significant increase in smoking cessations rates, but only among smokers who started on 21 mg/day patches after eight weeks of follow-up. No significant differences in smoking cessation rates were seen among smokers who started with the low dose nicotine or placebo patches.
