Abstract:  Drugs differing in their primary mechanism of action but having in common the ability to act as antidepressants such as fluoxetine (10 mg/kg SC), clomipramine (10 mg/kg IP), imipramine (10 mg/kg IP), desipramine (10 mg/kg IP) and (+/-)8-OHDPAT (0.03 mg/kg SC) increase extracellular concentrations of dopamine in the rat prefrontal cortex but not in the medial nucleus accumbens. Buspirone (1 mg/kg SC) increased dopamine both in the prefrontal cortex and in the nucleus accumbens. Extracellular 5HT was increased by fluoxetine, clomipramine and imipramine but not by desipramine while 8-OHDPAT and buspirone decreased it. These results raise the possibility that the property of stimulating dopamine transmission in the prefrontal cortex has a role in the antidepressant properties of these drugs.
