title: Faster onset of action of fluvoxamine in combination with pindolol in the treatment of delusional depression: a controlled study.
abstract: This double-blind, controlled study was undertaken to investigate whether the addition of pindolol could improve the therapeutic response to fluvoxamine of depressed patients with psychotic features. After a 1-week placebo run-in period, 72 patients received fluvoxamine 300 mg/day in combination with placebo or pindolol 7.5 mg/day. At study completion, 28 (80%) of 35 patients treated with fluvoxamine plus placebo and 29 (80.5%) of 36 patients treated with fluvoxamine plus pindolol were categorized as responders (reduction of their score on the 21-item Hamilton Rating Scale for Depression to 8 or less and on the Dimension for the Delusional Experience Rating Scale to 0). In the third and fourth weeks, the response rates were significantly superior in the fluvoxamine plus pindolol group (p = 0.0001, p = 0.023, respectively). Treatment response seemed to be unrelated to the demographic and the clinical characteristics recorded. No significant difference was found comparing plasma levels of fluvoxamine between groups, thus excluding a pharmacokinetic interaction. Other than mild nausea and sedation in a few patients, treatments were well tolerated. No medically significant adverse events occurred. Depressed patients with psychotic features who were administered pindolol experienced a more rapid improvement during fluvoxamine treatment. Thus, the combination of fluvoxamine with pindolol may be a useful pharmacologic strategy in the treatment of this disorder. A rapid clinical response in such patients is of relevance in clinical practice as well as in economic fields, given the direct and indirect costs of depression.
