(15) The agonist beta-carboline derivative ZK 93423, the anxiolytic cyclopyrrolones suriclone and zopiclone and the purines inosine and hypoxanthine all failed to inhibit antibody binding, supporting previous suggestions that these drugs may bind at non-benzodiazepine recognition sites on the CNS receptor.
(16) The behavioral effects of several new anxiolytics and putative anxiolytics were evaluated in two tests sensitive for anxiolytic activity.
(17) Pooled data for 427 patients with generalized anxiety disorders were analyzed retrospectively from six double-blind trials evaluating buspirone, a nonbenzodiazepine anxiolytic, in the treatment of generalized anxiety disorder.
(18) The nature of the effects favours an 'anxiolytic' hypothesis of melatonin action rather than the other hypotheses so far proposed.
(19) A good agreement was established between the anxiolytic (tranquilizing) effect of phenazepam after administration to rats per os and the rate of its supply to the systemic blood flow.
(20) The literature on the effects of anxiolytic and hypnotic drugs on performance in tasks requiring sustained attention is confusing.
