Two primary outcomes of efficacy and acceptability showed a possible advantage of benzodiazepines over placebo .
Low- quality evidence shows a possible superiority of benzodiazepine over placebo in the short-term treatment of panic disorders .
Due to these limitations , our results regarding the efficacy of benzodiazepines versus placebo provide only limited guidance for clinical practice .
BACKGROUND Panic disorder is characterised by recurrent unexpected panic attacks consisting of a wave of intense fear that reaches a peak within a few minutes .
Panic disorder is a common disorder , with an estimated lifetime prevalence of 1 % to 5 % in the general population and a 7 % to 10 % prevalence in primary care setting s. Its aetiology is not fully understood and is probably heterogeneous .
Panic disorder is treated with psychological and pharmacological interventions , often used in combination .
Although benzodiazepines are frequently used in the treatment of panic disorder , guidelines recommend antidepressants , mainly selective serotonin reuptake inhibitors ( SSRIs ) , as first-line treatment for panic disorder , particularly due to their lower incidence of dependence and withdrawal reaction when compared to benzodiazepines .
Despite these recommendations , benzodiazepines are widely used in the treatment of panic disorder , probably because of their rapid onset of action .
OBJECTIVES To assess the efficacy and acceptability of benzodiazepines versus placebo in the treatment of panic disorder with or without agoraphobia in adults .
Sertraline in the treatment of panic disorder: a flexible-dose multicenter trial.
BACKGROUND The serotonin selective reuptake inhibitors are increasingly being used for the treatment of panic disorder . We examined the efficacy and safety of the serotonin selective reuptake inhibitor sertraline hydrochloride in patients with panic disorder . METHODS One hundred seventy-six nondepressed out patients with panic disorder , with or without agoraphobia , from 10 sites followed identical protocol s that used a flexible-dose design . After 2 weeks of single-blind placebo , patients were r and omly assigned to 10 weeks of double-blind , flexible-dose treatment with either sertraline hydrochloride ( 50 - 200 mg/d ) or placebo . RESULTS Sertraline-treated patients exhibited significantly greater improvement ( P=.01 ) at end point than did patients treated with placebo for the primary outcome variable , panic attack frequency . Significant differences between groups were also evident for clinician and patient assessment s of improvement as measured by the Clinical Global Impression Improvement ( P=.01 ) and Severity ( P=.009 ) Scales , Panic Disorder Severity Scale ratings ( P=.03 ) , high end-state function assessment ( P=.03 ) , Patient Global Evaluation rating ( P=.01 ) , and quality of life scores ( P=.003 ) . Adverse events , generally characterized as either mild or moderate , were not significantly different in overall incidence between the sertraline and placebo groups . CONCLUSION Results support the safety and efficacy of sertraline for the short-term treatment of patients with panic disorder
