Combining rTMS With Varenicline to Prevent Smoking Lapse in Schizophrenia

Tobacco smokers with schizophrenia are known to be resistant smokers, with high rates of smoking and inability to quit in the long-term, often related to smoking relapse. This may relate to problems with frontal lobe function associated with schizophrenia, which make these patients have great difficulty in dealing with smoking withdrawal, urges and cravings. The current study will develop a combination approach that takes advantage of brain stimulation of the frontal lobes (repetitive transcranial magnetic stimulation (rTMS), in combination with the anti-smoking drug varenicline, to prevent smoking lapse using a well-established human laboratory method. Results from this study may have important implications for developing novel treatment approaches for smokers with schizophrenia.
