Eighteen patients with refractory depression (dysthymia with superimpo
sed major depression) were treated with a combination of fluvoxamine a
nd moclobemide for 6 weeks and compared with 18 patients treated with
fluvoxamine only. Both groups had improved only slightly after 8 weeks
of TCA treatment and 6 weeks of SSRI treatment. Two main observations
can be made concerning safety and efficacy. Firstly, side effects in
the SSRI-RIMA group were minimal. Secondly, the SSRI-RIMA combination
treatment significantly improved depression in refractory depressed pa
tients, with a decrease in depression of about 40%. The SSRI monothera
py group also significantly improved, though only by about 20%, indica
ting that positive effects of SSRI treatment may still develop even af
ter 12 weeks of treatment. In conclusion, the study gives further supp
ort to the hypothesis that SSRI-RIMA combinations may be safe and well
tolerated. This treatment may also offer some therapeutic advantages
in at least some patients who have not responded to conventional pharm
acological treatment.
