Synopsis

A double-blind clinical trial has been carried out to ascertain whether patients making a good recovery from depressive illness with tricyclic antidepressant medication derive any benefit from continuation of therapy with the same drug at a lower dose level. Of the 92 patients who entered the trial significantly fewer on active treatment relapsed during the six-month trial period: 22% as compared with 50% of patients receiving placebo. Patients with residual symptoms on entry to the trial derived more benefit from continuation therapy than patients who had made a complete recovery. The findings relate to a six-month trial period only, and any possible advantage of continuation therapy over a longer period remains uncertain.
