Cochrane PEARLS: antidepresivos y tabaquismo

Which antidepressants are effective in aiding long term smoking cessation?

Bottom line: Both bupropion and nortriptyline double the odds of cessation when compared to placebo (median NNT* = 11 and 10respectively). The efficacy of bupropion and nortriptyline appears to be similar to that for nicotine replacement and is not restricted to people with a history of depression or depressive symptoms during smoking abstinence. Selective serotonin reuptake inhibitors (SSRIs),venlafaxine and moclobemide show no evidence of benefit.* NNT = number needed to treat to benefitone individual.

Caveat: Bupropion can cause insomnia, dry mouth, nausea and seizures (estimated risk = 1 in1000). Nortriptyline can cause dry mouth, constipation, nausea and sedation, and can be dangerous in overdose.

Context: Smoking is the most preventable cause of premature death, accounting for about17% of all deaths in developed countries.
