Twenty-eight psychiatric patients older than 65 years with major depre
ssion with high probability of recurrence were enrolled in a 24-month
open label clinical trial aimed at evaluating the long-term efficacy a
nd safety of venlafaxine. All patients completed the acute phase of th
e study; 21 were responders and entered the follow-up period. During t
he continuation phase no relapse was observed. During the maintenance
period, 20% of the patients had a single new recurrence. No significan
t side effects were observed. The results demonstrate that venlafaxine
is both effective and safe in the long-term treatment of major depres
sion in geropsychiatric patients. (C) 1997 Elsevier Science B.V.
