NCT00124683

Brief Summary

Schizophrenic individuals are typically nicotine dependent smokers who find it difficult to quit smoking. The purpose of this study is to determine the effectiveness of bupropion SR (commonly known as Zyban) in combination with a nicotine transdermal patch (NTP), in helping schizophrenic individuals quit smoking. In addition, this study will evaluate how the combination of bupropion SR and NTP affects psychiatric symptoms and medication side effects.
