Résumé :
FRANÇAIS :
La tandospirone, nouvel anxiolytique, agit sur les sites de la 5HT. Le mode d'action serait différent de celui des barbituriques et des benzodiazépines, et le pouvoir toxicomanogène plus faible.
ENGLISH :
The behavioral pharmacology of tandospirone (SM 3997), a novel anxiolytic/antidepressant pyrimidinylpiperazine compound with selective pharmacological effects at he 5-HT binding site, was investigated in baboons. Animals administered 50 mg/kg/day i.g. tandospirone, showed few behavioral changes which decreased over 2 weeks. Substitution of vehicle for tandopirone after 7 weeks produced time-limited suppression of food intake, suggesting a mild withdrawal syndrome. Under an i.v. self -injection procedure, tandospirone did not maintain responding greater than vehicle, although cocaine and triazolam did. Under a drug discrimination procedure, tandospirone did not occasion drug-appropriate responding in baboons trained to descriminate lorazepam or pentobarbital and buspirone did not occasion drug-appropriate responding in the pentobarbital-trainig group. Tandospirone's profile of effects differs from those for barbiturates and benzodiazepines and suggest low abuse liability. (From author's abstract)
