Two selective serotonin reuptake inhibitors (SSRIs), citalopram and fluoxetine, both at a daily dose of 20 mg, were compared in patients with unipolar major depression treated in general practice. This was a multicentre, double-blind, randomized trial carried out in France. The duration of treatment was 8 weeks. Patients were assessed by means of the Montgomery-Asberg Depression Rating Scale (MADRS), the 17 items Hamilton Depression Rating Scale (HAMD) and the investigator's Clinical Global Impressions (CGI), Observed and spontaneously reported adverse events were also recorded. A total of 357 patients of both sexes, aged between 21 and 73 years, entered the double-blind phase of the trial. A clear reduction of both the MADRS and the HAMD mean total scores was observed in both treatment groups with no statistically significant differences between treatments. Apart from back pain recorded more frequently in the citalopram group, no significant difference was found between the two treatment groups with regard to adverse events, and both citalopram and fluoxetine were considered to be well tolerated. It was concluded that citalopram was as effective as fluoxetine in the treatment of unipolar major depression. Citalopram showed an earlier onset of recovery than fluoxetine.

In an open, clinical trial comprising a total of 49 depressed in-patients, a new selective 5-HT uptake inhibitor citalopram was administered by intravenous infusion in doses of 20-60 mg once daily for per 3 weeks. The therapeutic effect was assessed globally and by means of the CPRS subscale for depression (MADRS). About 40 per cent of the patients showed a complete response whereas about 25 per cent showed a partial response. Side effects which were rated globally and recorded according to a check-list were generally mild and infrequent. The side-effects most frequently observed were tremor, drowsiness, and dizziness which occurred in about 15 per cent of the patients.' Three patients were withdrawn prematurely because of nausea and one because of a skin rash. Cardiovascular recordings were normal except for one patient, who developed a hypertension which may have been related to the test drug. No pathological laboratory values were detected during the trial period. The authors conclude that intravenously administered citalopram is well suited for the treatment of depressed patients.
