Meclonazepam (Ro11-3128 or 3-methylclonazepam) is a benzodiazepine derivative. It exerts anxiolytic activity. Meclonazepam demonstrated anti-schistosomal action, it causes spastic paralysis, calcium influx and tegumental disruption in the parasites. Contracturant effect of meclonazepam is not a result of its binding to the worm benzodiazepine binding sites.
