Blood levels and acute response to bupropion.

Goodnick PJ.

Department of Psychiatry, University of Miami, FL 33136.

Twenty-three patients with major depressive disorder were treated with bupropion in an open-design protocol. Fifteen (65.2%) of the 23 responded with a more than 50% decrease in scores on the Beck Depression Inventory. Patients with trough blood levels of 10-29 ng/ml had a significantly better response than those with trough levels of 30 ng/ml or more. This preliminary result warrants further, double-blind evaluation.

Pharmacological responsiveness of winter depression.

Seasonal affective disorders (SADs) are disturbances of mood bearing a fixed relationship to season. Wintertime depression is the most widely accepted form of SAD. Full-spectrum, bright artificial light is the standard treatment for this syndrome. Tranylcypromine was effective in the treatment of 14 patients meeting both the National Institute of Mental Health and DSM-III-R criteria for winter depression. The average patient experienced a 91 percent reduction in depressive symptoms within 3 to 4 weeks of the initiation of this treatment. Desipramine initially appeared to be an effective treatment for winter depression. Eight patients started treatment with desipramine in October or November. One patient was unresponsive, and 8 patients appeared to be responsive but relapsed in the following 2 to 4 months. Twenty-five patients were subsequently treated with bupropion. One patient was unresponsive to bupropion, but the others experienced a substantial reduction in symptoms. Chronobiologic properties that might explain or predict the effectiveness of drugs used to treat winter depression are discussed.

High affinity dopamine reuptake inhibitors as potential cocaine antagonists: a strategy for drug development.

Rothman RB.

Laboratory of Clinical Science, National Institute of Mental Health, Bethesda, MD 20892.

The addictive and euphorogenic effects of cocaine are thought to result primarily from inhibition of dopamine reuptake. Although the potency of cocaine-like drugs as inhibitors of DA reuptake is highly correlated with their potency as reinforcers in animals, several potent DA reuptake blockers (bupropion, nomifensine, benztropine, and mazindol) have not been reported to produce addiction or euphoria in humans. Based on these observations in humans, DA reuptake inhibitors are classified into two groups; type 1 blockers, which produce addiction and euphoria, and type 2 blockers, which do not. Given that type 1 and type 2 blockers act at the same site (the DA transporter), the author suggests that type 2 agents may antagonize the effects of cocaine, and might prove useful in the treatment of cocaine addiction.
