Outcome Measures

Primary Outcomes (2)

  • Percentage of Change in Expired Air Carbon Monoxide (CO) at End of Week 1

    To evaluate the effects of meclizine alone on ad lib smoking, the percent decrease in expired air carbon monoxide (CO) at the end of week 1 (relative to baseline) will be compared (using ANOVA) between each meclizine group and placebo.

    After 1 week of treatment (relative to baseline)

  • Percentage of Change in Expired Air Carbon Monoxide (CO) at End of Week 3

    To evaluate the effects of meclizine as an augmentation treatment in conjunction with nicotine patch, the percent decrease in expired air carbon monoxide (CO) at the end of week 3 (relative to baseline) will be compared (using ANOVA) between each meclizine group and placebo.

    After 3 weeks of treatment (relative to baseline)

Secondary Outcomes (3)

  • Number of Participants Completing the Continuous 4 Week Abstinence From Smoking

    weeks 3-6 post quit date

  • Percentage of Change of CO at End of Week 1 When Comparing Abstinent Smokers Versus Non-abstinent Smokers

    After 1 week of treatment (relative to baseline)

  • Percentage of Change of CO at End of Week 3 When Comparing Abstinent Smokers Versus Non-abstinent Smokers

    After 3 weeks of treatment (relative to baseline)

Study Arms (3)

Placebo + Nicotine Patch

ACTIVE COMPARATOR

Subjects in this group will take placebo meclizine daily for the three weeks prior to their quit date. Subjects will also apply a 21mg/24h nicotine patch daily starting in the second week of pre-quit treatment. Placebo meclizine will be administered in two doses each day.

Drug: Nicotine PatchDrug: Placebo

25mg Meclizine + Nicotine Patch

EXPERIMENTAL

Subjects in this group will take 25mg of meclizine daily for the three weeks prior to their quit date. Subjects will also apply a 21mg/24h nicotine patch daily starting in the second week of pre-quit treatment. Meclizine will be administered in two doses each day.

Drug: MeclizineDrug: Nicotine Patch

50mg Meclizine + Nicotine Patch

EXPERIMENTAL

Subjects in this group will take 50mg of meclizine daily for the three weeks prior to their quit date. Subjects will also apply a 21mg/24h nicotine patch daily starting in the second week of pre-quit treatment. Meclizine will be administered in two doses each day.

Drug: MeclizineDrug: Nicotine Patch

Interventions

Pre-Quit Period: In this group, participants will take meclizine daily during the three week pre-quit period. The meclizine will be taken in two doses daily, one capsule with breakfast and one with dinner.

Also known as: Antivert
25mg Meclizine + Nicotine Patch50mg Meclizine + Nicotine Patch

Pre-Quit Period: During weeks two and three, participants will apply active 21mg/24h nicotine patches daily. Post-Quit Period: Following the quit-day these participants will apply active nicotine patches daily using the following dose schedule: 21mg/24h for four weeks, 14mg/24h for one week, and 7mg/24h for one week.

  • Have an afternoon expired air carbon monoxide (CO) reading of at least 10ppm;
  • Express a desire to quit smoking in the next thirty days.
  • Potential subjects must agree to use acceptable contraception during their participation in this study.
  • Potential subjects must agree to avoid the following during their participation in this study:
  • participation in any other nicotine-related modification strategy outside of this protocol;
  • use of tobacco products other than cigarettes, including pipe tobacco, cigars, e-cigarettes, snuff, and chewing tobacco;
  • use of experimental (investigational) drugs or devices;

You may not qualify if:

  • Inability to attend all required experimental sessions;
  • Hypertension (systolic \>140 mm Hg, diastolic \>100 mm Hg, coupled with a history of hypertension); subjects with no previous diagnosis of hypertension may have a screening blood pressure up to 160/100.
  • Hypotension with symptoms (systolic \<90 mm Hg, diastolic \<60 mm Hg).
  • Participants with a history of hypertension may, however, be allowed to participate in the study if the study physician or physician assistant determines that the condition is stable, controlled by medication, and in no way jeopardizes the individual's safety.
