1. The respiratory and psychomotor effects of two benzodiazepines used mainly as anticonvulsants were compared in healthy volunteers, using a double‐blind placebo controlled design. 2. Clobazam (10 and 20 mg) produced significantly fewer psychomotor side effects than clonazepam (0.5 and 1 mg). Neither drug at either dose affected the ventilatory response to CO2. 3. Although clonazepam produced significant effects on psychomotor performance, these did not correlate with plasma drug concentration. 4. Our studies provide further evidence that at the doses chosen clobazam is considerably less sedating than clonazepam. Further investigation is required into the tolerance profile of both drugs in patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
