Studies with oral lorazepam in anxiety neurosis associated with depressive symptomatology

Abstract

Twelve studies were undertaken under a common four-week protocol to investigate the efficacy of lorazepam compared with placebo in reducing the severity of moderate to severe anxiety in 264 patients also having significant depressive symptomatology. Analysis of the results indicated that lorazepam gave generally better anxiety relief than placebo; in the majority of comparisons the differences were substantial enough to be both statistically and clinically significant. No data were obtained evidencing significant toxicity in either treatment group.
