Alprazolam in the treatment of panic attack patients with and without major depression.

Sixteen patients with panic attacks were treated with alprazolam at an anxiety clinic between March 1982 and April 1983. For all patients charts were reviewed for baseline data and treatment results at 1 and 6 months. Quantitated self-rating scales and the Clinical Global Impressions scale were used to assess progress. Alprazolam appeared effective for panic, agoraphobia, and depressive symptoms in 7 of 11 patients with either panic disorder or agoraphobia with panic attacks (DSM-III-defined diagnoses); side effects occurred in 4 of the 11 patients, were limited to oversedation, and resulted in no discontinuations of drug. However, alprazolam was ineffective in controlling panic, agoraphobia, and depression in 5 patients with panic attacks and secondary major depressive episode; for this group of patients, side effects were apparently paradoxical and required drug discontinuation in 3 of these 5 patients.
