title: Comparison of full-dose versus half-dose pharmacotherapy in the maintenance treatment of recurrent depression.
abstract: Recent evidence points to the prophylactic efficacy of maintaining recurrent unipolar patients on the same dose of antidepressant medication that was used to treat the acute episode (Frank et al., 1990; Kupfer et al., 1992). Therefore, the question of whether such patients should be tapered to a lower maintenance dose after successful resolution of an acute episode is clearly important. In this report we describe a small randomized clinical trial in which patients were assigned to either full-dose or half-dose maintenance treatment for a period of 3 years. Survival analysis suggests that superior prophylaxis can be achieved with a full-dose as compared to a half-dose maintenance treatment strategy (p < 0.07). Mean survival time for the full-dose subjects was 135.17 (SE 19.75) weeks as compared to 74.94 (SE 19.78) weeks (median of 43.1 weeks) for the half-dose subjects. We conclude that for patients who have suffered several recurrences, full-dose maintenance treatment is the more effective prophylactic strategy.
