An open clinical trial of clonazepam in the treatment of patients with recurrent panic attacks.

Imipramine, phenelzine and alprazolam have each been shown to be efficacious in the treatment of panic disorder and in agoraphobia with panic attacks. Clonazepam, a 1,4 benzodiazepine derivative used mainly in neurology as an anti-epileptic, has specific pharmacodynamic and pharmacokinetic properties which would make it an advantageous antipanic agent. We report 8 cases of recurrent panic attacks which were successfully treated with clonazepam.
