Eficacia y seguridad del uso de medicamentos para la cesación de la adicción al tabaco: Revisión de guías de práctica clínica

Objective To review the efficacy and safety of pharmacotherapy for smoking cessation in the context of clinical practice guidelines (CPG). Methods A systematic review of CPGs was conducted, aimed at adapting recommendations for Colombia following the ADAPTE methodology. Outcomes comprised 6-months or higher smoking cessation rates and intervention safety. CPGs were peer-assessed based on DELBI. Results from aggregative studies included in selected CPGs were obtained. Results Pharmacotherapy doubles smoking cessation rates as compared with placebos (rates 25% and up to 27% when combined with counseling). The highest efficacy was observed for ansyolitic and antidepressive drugs (8.7% to 19.4%), and the lowest for nicotine replacement therapy -NRT- (5.2% to 12.9%). Nortriptiline shows an efficacy similar to that of bupropion (10%). With limited exceptions, combined pharmacotherapy for smoking cessation has shown no significant increase in cessation rates. Conclusions NRT, varenicline, bupropion and nortriptiline are effective treatments for smoking cessation. Combination of drugs deserves further clinical evidence and should be restricted to highly dependent smokers or initial therapeutic failure. Cost-effectiveness analyses might help to introduce smoking cessation programs in low and middle income countries.
