Moclobemide versus clomipramine in depressed patients in general practice. A randomized, double-blind, parallel,...

In a double-blind, randomized, controlled, multicenter clinical trial in general practice, lasting 7 weeks, a fixed dose of moclobemide (400 mg daily) was compared with a fixed dose of clomipramine (150 mg daily). A total of 147 patients with DSM-III-R major depression were included in the study. After a 1-week drug-free washout period, patients were stratified, according to total scores on the Hamilton Rating Scale for Depression (HAM-D), into two groups--HAM-D total scores, 11 to 15 points, and HAM-D total scores, 16 points or more. A comparison of the therapeutic effect of the two treatments was based on HAM-D total scores and the classification of patients into therapeutic response categories defined on the basis of total rating score, complete response, HAM-D < or = 7 points; partial response, HAM-D, 8 to 15 points; or no response, HAM-D > or = 16 points. The Newcastle Diagnostic Rating Scale (1965) was used to classify the patients into two groups, endogenous and nonendogenous. Adverse events were registered by use of the UKU side effect scale. Clinical global assessments of severity, efficacy, and tolerance were completed during the active treatment period. Compliance to treatment was based on levels of the drugs in plasma and the number of returned capsules. One hundred forty-two patients were evaluated for clinical effects. The results of the efficacy analyses showed therapeutic equivalence between moclobemide and clomipramine. There were no differences in the outcome of the two treatment groups or the two diagnostic groups (endogenous and nonendogenous).(ABSTRACT TRUNCATED AT 250 WORDS)
