Sixty-four healthy volunteers (aged 40 to 65 years), selected on the basis of fulfilling the ICD-10 F48.0 criteria for neurasthenia, were assigned randomly to four equal dosing groups, receiving 80, 160, or 320 mg of the combination b.

A double blind comparative trial of nomifensin and desimipramine in depression. Relationship between treatment and phenylethylamine excretion.

The effect of nomifensin (Hoechst 36984), a synthetic psychotropic drug whose structure differs from MAO inhibitors and tricyclics, was studied in a double blind comparative trial with desimipramine in patients with various depressive syndromes. Forty-three patients (23 in the nomifensin group and 20 in the desimipramine group) were studied for 6 weeks. Clinical follow-up was done with the Wittenborn scale (WPRS), Hamilton's rating scale for depression (HRS), Zung's scale (SDS), and the PEN inventory.
