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.
丁螺环酮是一种氮杂螺环酮衍生物及5-羟色胺1A受体部分激动剂,是首个引入医学用于治疗广泛性焦虑症的非苯二氮䓬类抗焦虑药。一系列严格对照的临床试验表明,其抗焦虑特性与多种苯二氮䓬类药物相似,且显著优于安慰剂。最近,还观察到了其抗抑郁作用。丁螺环酮似乎特别适用的临床适应症患者包括广泛性焦虑症患者、慢性焦虑症患者、焦虑的老年人,或许还有所有年龄段患有焦虑和抑郁混合症状的许多患者。迄今为止,对惊恐障碍患者进行的研究尚无定论,因此至少目前丁螺环酮不推荐用于惊恐障碍的常规治疗。丁螺环酮似乎对那些不要求立即获得满足感或与苯二氮䓬类反应相关的即时缓解的焦虑患者最有帮助。丁螺环酮起效较慢且较为渐进,但安全性更高且不存在产生依赖性的问题,二者相互平衡。最后,丁螺环酮除了具有“抗焦虑”特性外,是否还具有“治愈”特性,使患者能够随着时间的推移提高应对技能,这还需要进一步探索。
