Endogenously depressed patients who showed an antidepressant response to the tricyclic drug imipramine continued to show sustained well being after alpha-MPT was added whereas depression returned when small doses of PCPA were added for brief periods. In one patient the antidepressant response to imipramine occurred after pre- and continued treatment with alpha-MPT. Urinary excretion levels of MHPG in one of the patients studied longitudinally did not correspond to the direction of clinical affective state but did reflect anticipated changes during alpha-MPT treatment. Implications are that serotonergic mechanisms are likely involved in the anti-depressant effects of imipramine in man.
