title: Is beta-(4-chlorophenyl)-GABA a specific antagonist of substance P on cerebral cortical neurons?
abstract: Beta-(4-chlorophenyl)-GABA (Baclofen, Lioresal) antagonized the excitant actions of acetylcholine and substance P to comparable extents. L-glutamate-induced excitation was affected to a lesser extent. These findings do not support the suggestion that beta-(4-chlorophenyl)-GABA is a specific substance P antagonist.
