[Buspirone: a new non-benzodiazepine anxiolytic drug]

Buspirone is a new drug with ansiolitic properties which chemical structure and mechanism of action is different from the classical drugs traditionally used for this symptom. Its farmacokinetic characteristics make it a convenient drug to be used for oral administration. Buspirone's double-blind controlled clinical studies contrasted with benzodiazepines have shown that buspirone has an ansiolitic effect close to them but without sedation or relaxation. Other secondary effects appear with a smaller incidence with buspirone. These properties make buspirone very efficient in anxiety treatment.
