Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bupropion has different effects on D2 dopamine receptors according to genotype.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Open, one arm, single sequence, 2-period, study stratified into 2 DRD2 genotype groups For subjects who volunteer to cease smoking, genotypes are investigated. Twelve subjects are enrolled (6 - DRD2 Taq1A1 allele, 6 - DRD2 Taq1A2 homozygotes). Subjects receive baseline raclopride PET (High Specific Activity, Low Specific Activity).

* Period 1 Subjects receive 150 mg of bupropion SR every day. After 1 week of medication, pharmacokinetic and PET studies are performed.
* Period 2 Subjects receive 150 mg of bupropion SR twice a day. After 1 week of medication, pharmacokinetic and PET studies are performed.
