Gepirone, a selective serotonin (5HT1A) partial agonist in the treatment of major depression.
1. The present study assessed the potential antidepressant action of gepirone hydrochloride, an azapirone serotonin (5-HT1A) partial agonist in patients with major depression. 2. Overall, gepirone demonstrated a significant antidepressant activity within the entire patient group (p less than 0.001). However, when subjects were stratified based upon the presence or absence of DSM III-R melancholic features, the melancholic depressives showed little change in weekly depression ratings compared to patients without melancholic symptoms (p less than 0.001). 3. Similarly, patients who were more severely ill at the pretreatment period had less improvement compared to those with more modest illness severity (p less than 0.001). 4. These observations compliment those of prior studies suggesting antidepressant activity for gepirone. 5. However, a consistent efficacy comparable to conventional neuronal reuptake inhibitor antidepressants remains to be established in patients with more severe depression characterized by melancholic features.
