RT Journal Article SR Electronic T1 Update on pharmacologic and nonpharmacologic therapies for smoking cessation JF Canadian Family Physician JO Can Fam Physician FD The College of Family Physicians of Canada SP 994 OP 999 VO 54 IS 7 A1 Jason Schmelzle A1 Walter W. Rosser A1 Richard Birtwhistle YR 2008 UL http://www.cfp.ca/content/54/7/994.abstract AB OBJECTIVE To review the evidence on the efficacy and safety of pharmacologic and nonpharmacologic therapies for smoking cessation. QUALITY OF EVIDENCE MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews were searched for randomized controlled trials, meta-analyses, and systematic reviews (level I evidence) pertinent to pharmacologic and nonpharmacologic smoking cessation therapies. MAIN MESSAGE Pharmacologic smoking cessation aids are recommended for all smokers trying to quit, unless contraindicated. A new pharmacologic smoking cessation aid, varenicline, is now available in Canada. Level I evidence at 1-year follow-up indicates that it is effective for smoking cessation. Adverse effects include nausea, insomnia, and abnormal dreaming. Nausea is mild or moderate and decreases over time. Varenicline is more effective than placebo or bupropion. Counseling also increases the likelihood of achieving cessation. CONCLUSION Preliminary data indicate that varenicline is more effective than other available pharmacologic smoking cessation aids. Pharmacologic therapy should be combined with nonpharmacologic therapy.
