Brief Summary

Cigarette smoking continues to be a major public health problem. Tobacco dependence interventions, as recommended by the USPHS Clinical Practice Guideline are not effective for all smokers. A need exists for new medications to treat various aspects of tobacco dependence, such as the reinforcing effects of nicotine, relief of nicotine withdrawal symptoms and prevention of early relapse. The neurobiology of the effect of methylphenidate is similar to that of the reinforcing effects of nicotine. In a small previous study, methylphenidate was reported to improve nicotine withdrawal symptoms and short term quit rates. Methylphenidate is well tolerated, has low abuse potential, and is less expensive compared to other tobacco dependence interventions. ConcertaTM, a long acting preparation of methylphenidate, is administered once a day, has similar bioavailability as the generic drug administered 3 times a day and has an overall similar or improved efficacy compared to generic methylphenidate. We plan to obtain preliminary efficacy data in a randomized, placebo-controlled phase II study assessing the effect of methylphenidate in cigarette smokers for increasing 7-day point prevalence smoking abstinence at end of treatment and 7-day point prevalence and prolonged smoking abstinence at 6-months. Critical and systematic evaluations of newer, innovative, and well-tolerated treatments to help treat tobacco use and dependence will provide a wider choice of therapeutic agents to smokers wishing to become abstinent from tobacco use.

  • Are willing to make an attempt to stop smoking
  • Are able to participate fully in all aspects of the study
  • Have been provided with, understand, and have signed the informed consent

You may not qualify if:

  • Have clinically significant levels of current depression as assessed by CESD and determined by the physician; or have a life-time diagnosis of bipolar disorder, schizophrenia or dementia as determined by physician investigator
  • Are currently (in previous 30 days) using any tobacco treatment program (i.e., behavioral therapy, nicotine replacement therapy, bupropion SR, varenicline, clonidine or nortriptyline)
  • Have used an investigational drug within the 30 days prior to enrolling in this study
  • Alcohol or drug abuse or dependence within the past year as assessed by the study investigators using CAGE questionnaire and the Drug Abuse Screening Test 20 (DAST-20)

The following birth control measures are acceptable: approved hormonal contraceptive medications or devices, approved intra-uterine contraceptive devices, the use of two combined barrier methods (diaphragm with spermicide or condom with spermicide), birth control pills, injections, intrauterine device \[IUD\], abstinence, or surgical sterilization of subject or of monogamous partner.
  • Have a history of any major cardiovascular event in the past 6-months including unstable angina, acute MI or coronary angioplasty
  • Have clinically significant acute or chronic, progressive or unstable neurologic (dementia, delirium or seizure disorder), hepatic, renal, cardiovascular, respiratory or metabolic disease that would limit participation in the study
  • Are currently on the following prescribed medications known to interact with methylphenidate and not able to stop the medication during the study period: stimulants, warfarin, anticonvulsants, antidepressants, antipsychotics, monoamine oxidase inhibitors, clonidine, theophylline and pseudo-ephedrine
  • Uncontrolled hypertension (\>160/100) or tachycardia (Heart rate \>110)

  • have an ECG with significant arrhythmias or abnormal conduction, which in the opinion of the physician investigator preclude participating in the study.
