Summary

Tianeptine is a new antidepressant that, in animals, has a faciliting effect on both working and reference memory. To investigate the effects of tianeptine on vigilance and memory in humans, a placebo-controlled cross-over study was performed in 20 healthy volunteers. The duration of each treatment period was 7 days and the dosage of tianeptine 37.5 mg per day. The evaluations consisted of 3 computerized tests assessing alert function, continuous recognition and semantic facilitation. A memory questionnaire and the Rey test (15 words) were added. The analysis of variance (cross-over type) performed on the results did not show any significant difference between the evolution of these tests on tianeptine and on placebo in young healthy subjects, at the height of their intellectual capacities. In this study, tianeptine respected the vigilance as well as the performances of the healthy volunteers and did not impair their memory and cognitive processes, which distinguishes it from many psychotropic drugs. Nevertheless, tianeptine did not produce a faciliting effect on these processes in healthy volunteers. These results allow us to propose new clinical trial with tianeptine in order to investigate its effects on older volunters and patients complaining of memory disorders.

Résumé

Résumé

La tianeptine est un nouvel antidépresseur qui possède chez l’animal un effet faciliteur de l’apprentissage et de la mémoire. Les effets de la tianeptine sur la vigilance et la mémoire ont été recherchés chez l’homme au cours d‘une étude réalisée en cross-over contre placebo chez 20 volontaires sains jeunes. La durée de chacune des périodes de traitement était de 7 jours et la posologie de tianeptine de 37,5 mg par jour. Les évaluations consistaient en 3 tests informatisés étudiant respectivement la fonction d’alerte, la mémoire de reconnaissance immédiate et la vitesse de facilitation sémantique. Un questionnaire de mémoire et le test des 15 mots de Rey étaient aussi remplis. L‘analyse de variance (de type cross-over) appliquée aux résultats n ’a montré aucune différence significative entre les évolutions de ces tests sous tianeptine et sous placebo chez des sujets sains jeunes, au maximum de leurs capacités intellectuelles. Au cours de cette étude, ta tianeptine a respecté aussi bien la vigilance que les performances des volontaires sains et n’a entraîné aucune altération de leurs processus mnésiques et cognitifs, ce qui la distingue de nombreux psychotropes. Aucun effet facilitateur de ces processus n’a cependant été mis en évidence chez des sujets sains. Ces résultats permettent d’envisager de nouvelles études cliniques avec la tianeptine afin d’étudier ses effets chez te volontaire sain plus âgé ainsi que chez le patient se plaignant de troubles mnésiques.
