Topiramate Alone and in Combination With the Nicotine Patch for Smoking Cessation: A Pilot Study
Topiramate Alone and in Combination With the Nicotine Patch for Smoking Cessation: A Pilot Study

Specific aims:

  1. To obtain pilot data on 4-week continuous quit rates associated with 10 weeks of treatment with topiramate or placebo or topiramate plus nicotine patch for smoking cessation.
  2. To obtain pilot data on the effects of 10 weeks of topiramate versus placebo versus combination of topiramate plus nicotine patch on nicotine withdrawal symptoms, smoking satisfaction, and adverse effects during smoking cessation.
  3. To obtain pilot data on weight gain over 10 weeks with topiramate versus placebo versus combination of topiramate plus nicotine patch for smoking cessation.

This is a 10-week, randomized, double-blind, single-site study of treatment with either: topiramate, or placebo, or topiramate plus nicotine patch. Approximately, 90 subjects ages 18-65 who smoke at least 10 cigarettes per day will be screened for study participation, with the intention of 60 subjects being eligible for randomized treatment (20 per arm).

  • Drug: Placebo (sugar pill)
    patients receive
    Other Name: sugar pill
  • Drug: topiramate
    25 mg per day for one week, 50 mg per day for one week, 100 mg per day for one week, 200 mg per day for 5 weeks, then one week taper
    Other Name: topimax
  • Drug: nicotine patch
    subjects receive 10 weeks of topiramate with a dosage starting at 25 mg per day. At week two (quit date) subjects increase to 50 mg/day and gradually increase to 200 mg/day for a total time of 10 weeks. On the quit date (after 2 weeks of medication use), subjects also use 21mg patch for 8 weeks.

    Intervention: Drug: topiramate
  • Active Comparator: nicotine patch
    topiramate plus nicotine patch. Subjects receive 10 weeks of topiramate with a dosage starting at 25 mg per day. At week two (quit date) subjects increase to 50 mg/day and gradually increase to 200 mg/day for a total time of 10 weeks.
