Zimelidine: A therapeutic and pharmacokinetic study in depression

Abstract
Zimelidine, a bicyclic compound with a strong effect on the neuronal reuptake of 5-hydroxytryptamine and with weak anticholinergic actions, was evaluated for its antidepressant efficacy in a double-blind comparative trial with amitriptyline. In doses of 200 mg a day it was found to be as effective as 150 mg amitriptyline, but with significantly less subjective side-effects. The plasma concentration of zimelidine and its metabolite, norzimelidine, showed no significant correlation with therapeutic outcome.
