The model of LSD potentiated apomorphine hypermotility [5] was used to classify different atypical antidepressants (danitracen, mianserin, cyproheptadine) and pizotifen. All drugs have been shown to inhibit specifically the locomotor activity potentiating effect of LSD in a low dosage range (0.1-0.5 mg/kg i. p.) without influencing the apomorphine effect. Since there is some evidence that the effect of LSD is due to the inhibition of the activity of serotonergic raphe neurons, the marked antagonizing effects of danitracen, mainserin, cyproheptadine and pizotifen are regarded to be an expression of pronounced antiserotonin activity.
