These drugs were better tolerated than tricyclics and benzodiazepines as they had a low risk of dependence and overdosing complications .
The serotonergic , noradrenergic and GABAergic pathways play a major role in the fear network and in the physiopathology of PD .
INTRODUCTION Panic disorder ( PD ) is a prevalent psychiatric disorder characterized by unexpected and recurrent panic attacks .
PD patients present significant psychosocial impairment and a high risk of psychiatric comorbidities and suicide .
PD should be treated effectively as soon as the symptoms emerge because the longer these patients remain without treatment , the worse the prognosis will be .
SSRIs and SNRIs are the first-line compounds in the treatment of PD .
A comparison of citalopram and paroxetine in the treatment of panic disorder: a randomized, single-blind study.
BACKGROUND Serotonin Selective Re-uptake Inhibitors ( SSRIs ) are the drugs of choice for treating panic disorder ( PD ) . In vitro studies have shown different pharmacodynamic profiles for SSRIs , but their clinical relevance is still unknown . Paroxetine , the SSRI with the strongest serotonergic effect , also shows significant cholinergic and noradrenergic activities . In this class of drugs , citalopram is the most selective for serotonin . We compared these two drugs and their effectiveness and tolerability in a sample of patients with PD in a two-month treatment course . METHOD Fifty-eight patients with PD were r and omly assigned to either the paroxetine or the citalopram treatment group in a single-blind , r and omized design . Each patient was assessed at days 0 , 7 and 60 by the Panic Associated Symptoms Scale ( PASS ) , the Sheehan Disability Scale ( SDS ) and the Fear Question naire ( FQ ) . Primary outcome measures were the percentage of patients free of panic attacks , anticipatory anxiety and phobic avoidance in the last week of the trial and the percentage of good responders , as defined by a reduction of at least 50 % from baseline of both PASS and SDS global scores at day 60 . RESULTS At day 60 , 86 % of patients receiving citalopram and 84 % of those receiving paroxetine responded well to treatment . No significant differences between the two drugs were found . Both were well tolerated , although sexual side effects and weight gain were frequent . Anticipatory anxiety decreased significantly after the first week of treatment , and no initial worsening in the panic attacks was observed . CONCLUSION Paroxetine and citalopram show similar anti-panic properties and a good tolerability profile . Our results support evidence that the serotonergic system plays a significant role in the anti-panic properties of these two SSRIs
