About this study

Official title: The Effects of Craving and Abstinence From Cigarettes on Brain Metabolism in Smokers.

Craving and withdrawal from smoking cigarettes are major factors for relapse. We investigated craving for cigarettes in smokers undergoing pharmacological treatment with Bupropion (Zyban). We compare cue-induced reactivity to smoking videos in smokers who were successfully treated with Bupropion to smokers who are still smoking. We measured the brain's metabolic activity in response to smoking and neutral cues in Positron Emission Tomography using FDG.

Read the detailed description

Craving and withdrawal from smoking cigarettes are major factors for relapse. We investigated craving for cigarettes in smokers undergoing pharmacological treatment with Bupropion (Zyban)for 2 months. We compare cue-induced reactivity to smoking videos in smokers who were successfully treated with Bupropion to smokers who are still smoking. We measured the brain's metabolic activity after exposure to videotapes showing smoking and neutral scenes in Positron Emission Tomography using FDG. There were 2 scanning sessions, one with a smoking videotape and one with a neutral video separated by a week. So far we have compared the brain's metabolic activity in 6 abstinent smokers and 6 still smokers.

Questions about this trial

What is this clinical trial studying?

A study testing Bupropion (Zyban) in people with Nicotine Dependence, run by Tel-Aviv Sourasky Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 May 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Brain metabolic activity (FDG) in response to craving and neutral cues. (time frame: 30-40 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00267813, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 May 2008.
