[A comparative pharmacological study of the serotoninergic antidepressants tetrindole and fluoxetin]

Tetrindol, a selective inhibitor of MAOA (predominantly of serotonin oxidase) and fluoxetine, an inhibitor of serotonin neuronal uptake, were studied in psychotropic tests on mice and rats. Both drugs significantly intensified 5-hydroxytriptophan-induced head twitching, reduced the effect of reserpine and the destructive action of maximal electroshock and the scopalamine-induced transient disruption of memory in a test for conditioned response of passive avoidance in rats and mice. In a behavioral swimming test the drugs were less active. In potentiation of 5-HT activity both drugs were approximately equal.
