title: Effect of the benzodiazepine receptor antagonist Ro 15-1788 on the anticonvulsant and anticonflict actions of MK-801.
abstract: MK-801, phenobarbital and clonazepam blocked convulsions elicited in mice by bicuculline. Treatment with Ro 15-1788 antagonized the anticonvulsant action of clonazepam, but not MK-801 or phenobarbital. The anticonflict effect in the rat of chlordiazepoxide, but not MK-801, was antagonized by Ro 15-1788. Despite having certain benzodiazepine-like effects in vivo, MK-801 does not act directly or indirectly via receptors for benzodiazepines.
