Clobazam: uncontrolled and standard controlled clinical trials.

1 In an uncontrolled clinical trial, carried out in 11 psychiatric patients with the clinical diagnoses of anxiety neurosis and depressive neurosis, clobazam, a new benzodiazepine preparation, in the dosage range 10-60 mg daily produced statistically significant improvement in the total and both factor scores of the Hamilton Anxiety Scale (HAM-A). The lowest mean total HAM-A scores occurred with a mean clobazam dosage of 48 mg daily. 2 Results of the uncontrolled clinical trial were further substantiated in a standard-controlled clinical study in which no statistically significant difference between the therapeutic effectiveness of clobazam and diazepam could be revealed. The lowest mean total HAM-A scores occurred with a mean clobazam dosage of 49 mg daily. There was a lower incidence of adverse effects reported in patients receiving clobazam than in those taking the control drug (diazepam).
