Fluoxetine's effect (30 mg, 60 mg, and placebo) on postcessation weight gain was studied among participants from a randomized, double-blind 10-week smoking cessation trial who met strict criteria for abstinence and drug levels. It was hypothesized that (a) fluoxetine would dose-dependently suppress postcessation weight gain and (b) drug discontinuation would produce dose-dependent weight rebound. During the on-drug phase, placebo participants gained weight linearly (M = 2.61 kg). exceeding both fluoxetine groups (30-mg group M = 1.33 kg, 60-mg group M = 1.25 kg). Weight suppression was initially greater for 60 mg than 30 mg, but both were followed by weight gain. Six months off drug produced greater dose-dependent weight rebound for 60 mg than 30 mg or placebo. Considering both on- and off-drug phases, weight gain for 60 mg of fluoxetine (M = 6.5 kg) was comparable with that for placebo (M = 4.7 kg) but greater than that for 30 mg (M = 3.6 kg). Fluoxetine appears to forestall postcessation weight gain, allowing time for the weight-conscious smoker to focus on quitting smoking rather than on preventing weight gain.
在一项为期10周的随机双盲戒烟试验中,对符合严格戒烟和药物水平标准的参与者研究了氟西汀(30毫克、60毫克和安慰剂)对戒烟后体重增加的影响。研究假设为:(a)氟西汀将呈剂量依赖性抑制戒烟后体重增加;(b)停药将产生剂量依赖性体重反弹。在服药阶段,安慰剂组参与者体重呈线性增加(M = 2.61千克),超过了两个氟西汀组(30毫克组M = 1.33千克,60毫克组M = 1.25千克)。最初,60毫克组的体重抑制作用大于30毫克组,但随后两组均出现体重增加。停药6个月后,60毫克组比30毫克组或安慰剂组产生更大的剂量依赖性体重反弹。综合服药和停药阶段来看,60毫克氟西汀组的体重增加量(M = 6.5千克)与安慰剂组(M = 4.7千克)相当,但大于30毫克组(M = 3.6千克)。氟西汀似乎可以延缓戒烟后体重增加,让关注体重的吸烟者有时间专注于戒烟而非预防体重增加。
