Pharmacology of anti-anxiety drugs with special reference to clobazam

1 In several studies clobazam exhibited a potency which ranges between that of chlordiazepoxide and diazepam. Its anxiolytic and anti-aggression effects are produced by doses usually ranging below those that cause disorders in motor activity. 2 This separation was demonstrable to an even greater degree with the desmethyl metabolite. The activity of the metabolite, however, was weaker than that of the original substance. 3 The advantage of clobazam compared with the 1.4 benzodiazepines lies mainly in the fact that motor activity is influenced only after very high doses, these doses being markedly above those required to induce tranquillizing and anti-agression activities. 4 Clobazam has no marked effect on the cardiovascular system, respiration of excretion.
