We observed the same finding when classes of antidepressants were compared with placebo .
When looking at dropouts due to adverse effects , which can be considered as a measure of tolerability , we found moderate- quality evidence showing that antidepressants as a whole are less well tolerated than placebo .
The identified studies comprehensively address the objectives of the present review .Based on these results , antidepressants may be more effective than placebo in treating panic disorder .
Antidepressants may also have benefit in comparison with placebo in terms of number of dropouts , but a less favourable profile in terms of dropout due to adverse effects .
However , the tolerability profile varied between different classes of antidepressants .
BACKGROUND Panic disorder is characterised by repeated , unexpected panic attacks , which represent a discrete period of fear or anxiety that has a rapid onset , reaches a peak within 10 minutes , and in which at least four of 13 characteristic symptoms are experienced , including racing heart , chest pain , sweating , shaking , dizziness , flushing , stomach churning , faintness and breathlessness .
It is common in the general population with a lifetime prevalence of 1 % to 4 % .
The treatment of panic disorder includes psychological and pharmacological interventions .
Amongst pharmacological agents , the National Institute for Health and Care Excellence ( NICE ) and the British Association for Psychopharmacology consider antidepressants , mainly selective serotonin reuptake inhibitors ( SSRIs ) , as the first-line treatment for panic disorder , due to their more favourable adverse effect profile over monoamine oxidase inhibitors ( MAOIs ) and tricyclic antidepressants ( TCAs ) .
Several classes of antidepressants have been studied and compared , but it is still unclear which antidepressants have a more or less favourable profile in terms of effectiveness and acceptability in the treatment of this condition .
OBJECTIVES To assess the effects of antidepressants for panic disorder in adults , specifically:1 .
to determine the efficacy of antidepressants in alleviating symptoms of panic disorder , with or without agoraphobia , in comparison to placebo;2 .
to review the acceptability of antidepressants  in panic disorder , with or without agoraphobia , in comparison with placebo ; and 3 .
to investigate the adverse effects of antidepressants  in panic disorder , with or without agoraphobia , including the general prevalence of adverse effects , compared to placebo .
Global measures of outcome in a controlled comparison of pharmacological and psychological treatment of panic disorder and agoraphobia in primary care.
BACKGROUND Panic disorder , with and without agoraphobia , is a prevalent condition which presents primarily in general practice . Previous clinical outcome studies have been conducted mainly in specialist university departments or hospital setting s , and have tended to employ complex rating scales that are not well suited for use as outcome measures in primary care . AIM To evaluate the outcome , in a primary care setting , of fluvoxamine versus cognitive behaviour therapy , each used alone and in combination in a double-blind placebo-controlled framework , balanced for therapist contact . METHOD A total of 149 patients satisfying DSMIII-R criteria for panic disorder were r and omly allocated to receive one of the following : fluvoxamine , placebo , fluvoxamine plus cognitive behaviour therapy , placebo plus cognitive behaviour therapy , and cognitive behaviour therapy alone . These five treatment groups represent the minimum number acceptable for such a comparison to be made . All patients received an identical schedule of contact over 13 weeks . Measures of symptom severity , general health and social disruption were taken at entry point and end point ; measures of change in symptoms were taken at end point only . Outcome was reported in terms of brief global ratings of severity of illness and change in symptoms , and of ratings of general health and social disruption that are suitable for use in general practice . RESULTS All active treatment groups showed statistically significant advantages over placebo over a range of outcome ratings . The groups employing cognitive behaviour therapy showed the most robust and consistent response . CONCLUSION The brief global measures reported here proved adequate to the task of assessing treatment outcome . Results indicate that treatments including cognitive behaviour therapy can be effective in the treatment of panic disorder and agoraphobia in primary care
