Abstract
In a double-blind, placebo-controlled, crossover study, the effects of thereapeutic doses of the new tricyclic antidepressant tianeptine on cardiovascular function were closely monitored in 21 healthy volunteers during a 2-week treatment period. Blood pressure measurements, ECG recording, 24-h Holter monitoring, and echocardiography were carried out at 1-week intervals. Isotopic ventriculography was measured twice under each treatment. Tianeptine did not produce orthostatic hypotension or increase heart rate. No ECG changes could be observed and the cardiac conduction time remained unchanged. One subject presented with an increase in the frequency of ventricular premature beats that could not be definitely attributed to the drug. Cardiac output assessed at rest and after bicycle exercise stress test was not altered. The present study suggests that tianeptine is a tricyclic antidepressant endowed with less cardiac toxicity than classical tricyclic antidepressants.
