A Comparison of Bupropion SR and Placebo for Smoking Cessation

This study has been completed.

Sponsors and Collaborators: University of Maryland
Department of Veterans Affairs
Information provided by: University of Maryland
ClinicalTrials.gov Identifier: NCT00176449
  Purpose

The purpose of this study is to examine whether the adjunctive use of bupropion SR in the context of a psychoeducational program modified for people with schizophrenia might improve the likelihood of successful abstinence in this population. If bupropion SR is effective for reducing cigarette smoking, then it will be important to determine if decreased nicotine intake is associated with a worsening of psychotic, anxiety or depressive symptoms. In addition, it would be important to determine the effect that a reduction in nicotine stimulation would have on patient's cognitive functioning, as nicotinic receptors have been shown to regulate attention and memory function, and it is hypothesized that these functions are normalized by acute nicotine administration in people with schizophrenia

Further study details as provided by University of Maryland:

Primary Outcome Measures:
  • The Fagerstrom Test for Nicotine Dependence, expired CO level, and urine cotinine will be used to determine if bupropion SR, when used as an adjunct to antipsychotic medication, is superior to placebo for helping patients with schizophrenia improve their [ Time Frame: Expired CO weekly, Fagerstrom baseline and end of study, Urine cotinine baseline, week 2 and week 8 ] [ Designated as safety issue: No ]
  • Neuropsychological testing will be used to determine the effects of smoking cessation on patient's attention and memory function. [ Time Frame: Beginning and end of study ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • BPRS, SANS, EPRS, and body weight will be used to determine the effects of bupropion SR and smoking cessation on patients' positive and negative symptoms, level of functioning, and physical health. [ Time Frame: Baseline, week 2, 4, 8, and 14 ] [ Designated as safety issue: Yes ]
  • To determine whether responses to the Smoking Consequences Questionnaire, Change Assessment Scale, Temptation to Smoke Scale, Decisional Balance Scale, and Smoking Abstinence Self-Efficacy Scale correlate with successful smoking cessation.
