The pharmacological treatment of delusional depression.

The authors investigated the pharmacological treatment of delusional depression by assigning patients on a random double-blind basis to amitriptyline alone, perphenazine alone, or a combination of the two. Fourteen (78%) of the 18 patients assigned to amitriptyline plus perphenazine were responders, compared with seven (41%) of 17 patients treated with amitriptyline alone and three (19%) of the 16 patients treated with perphenazine alone. The combination of amitriptyline and perphenazine was clearly superior (p less than .01).
