Buspirone in clinical practice.
Buspirone, an azapirone derivative and a 5-HT1A partial agonist, is the first nonbenzodiazepine anxiolytic introduced into medicine for the treatment of generalized anxiety disorder. A series of well-controlled clinical trials demonstrated that its anxiolytic properties were similar to those of various benzodiazepines and significantly better than placebo. More recently, antidepressant effects were also observed. Patients with clinical indications for which buspirone seems to be particularly appropriate are those with generalized anxiety disorder, those with chronic anxiety, the anxious elderly, and, perhaps, many patients of all ages who suffer from mixed symptoms of anxiety and depression. Studies conducted with patients suffering from panic disorder have so far been inconclusive, and thus buspirone is, for the present at least, not recommended for routine treatment of panic disorder. Buspirone seems to be most helpful in anxious patients who do not demand immediate gratification or the immediate relief they associate with the benzodiazepine response. Slower and more gradual onset of anxiety relief is balanced by the increased safety and lack of dependency-producing aspects of buspirone. Finally, whether or not buspirone may possess "curative" properties, in addition to "anxiety-suppressant" properties, that allow the patient to improve coping skills with time requires further exploration.
