At present, none of the double-blind placebo-controlled studies demons
trated that concurrent treatment with antidepressant and lithium haste
ned clinical response in nonresistant depressed patients. In these stu
dies, however, the antidepressants tested were not predominant or sele
ctive serotenergic antidepressants. In the present study, an uncontrol
led open study involving concurrent treatment with trazodone and lithi
um was performed as a preliminary study. As a result, two of six patie
nts dramatically improved within a week. The present findings suggest
that concurrent treatment with trazodone and lithium can hasten clinic
al response in some depressive patients. Thus, the question whether co
ncurrent treatment with predominant or selective antidepressant and li
thium can hasten clinical response deserves a further double-blind pla
cebo-controlled study. (C) 1998 John Wiley & Sons, Ltd.
