title: Effects of differing nicotine-replacement doses on weight gain after smoking cessation.
abstract: OBJECTIVE
  To prospectively assess effects of doses of a nicotine-replacement agent on weight gain in men and women after smoking cessation.
  
  
  METHODS
  Four-week, randomized, double-blind clinical trial.
  
  
  METHODS
  Outpatient medical clinic.
  
  
  METHODS
  Healthy volunteers who smoked at least 10 cigarettes per day.
  
  
  METHODS
  Pharmacologic: Random assignment to 0, 2, or 4 mg of nicotine polacrilex on a fixed-dose schedule (one piece per hour while awake). Behavioral: Brief, medical/behavioral counseling regarding smoking cessation.
  
  
  METHODS
  Weight change as a function of dose and gender only in participants abstinent for all 4 week. (Self-reported abstinence verified by breath carbon monoxide levels).
  
  
  RESULTS
  Weight change in women abstinent for 4 weeks (n = 16) was +1.69, +0.33, and -0.26 kg in the placebo, 2-mg, and 4-mg groups, respectively, compared with +1.60, +1.45, and +1.18 kg for the men who were abstinent for 4 weeks (n = 19). Medication use did not differ as a function of dose or gender.
  
  
  CONCLUSIONS
  Nicotine polacrilex suppressed, in a dose-related fashion, weight gain after smoking cessation in successfully treated women. Weight gain was not shown to be suppressed in men, possibly because of small sample size.
