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.
