      Abstract

      The effects of oral yohimbine (20 mg) or placebo or both drugs on plasma homovanillic acid (HVA) were evaluated in patients with panic disorder and normal controls. Panic disorder patients had similar HVA values at baseline compared with normal controls, and yohimoine failed to produce appreciable changes in HVA in both groups. These findings are discussed within the context of catecholaminergic theories of panic disorder.
