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 .
Placebo-controlled study of gabapentin treatment of panic disorder.
A r and omized , double-blind , placebo-controlled , parallel-group study was conducted to evaluate the efficacy and safety of gabapentin in relieving the symptoms of  panic disorder . One hundred three patients were r and omly assigned to receive double-blind treatment with either gabapentin ( dosed flexibly between 600 and 3,600 mg/day ) or placebo for 8 weeks . No overall drug/placebo difference was observed in scores on the Panic and Agoraphobia Scale ( PAS ) ( p = 0.606 ) . A post hoc analysis was used to evaluate the more severely ill patients as defined by the primary outcome measure ( PAS score > or = 20 ) . In this population , the gabapentin-treated patients showed significant improvement in the PAS change score ( p = 0.04 ) . In patients with a PAS score of 20 or greater , women showed a greater response than men regardless of treatment . Adverse events were consistent with the known side effect profile of gabapentin and included somnolence , headache , and dizziness . One patient experienced a serious adverse event during the study . No deaths were reported . The results of this study suggest that gabapentin may have anxiolytic effects in more severely ill patients with panic disorder
