Phaclofen (3-Amino-2-(4-chlorophenyl)propanephosphonic acid) is a selective GABAB receptor antagonist, which can partially antagonize the sedative effect of (-)-baclofen, and reversibly antagonize the inhibition of cholinergic convulsive response of guinea pig ileum and distal colon by baclofen or GABA. Inhibits the cholinergic convulsive response in the guinea pig ileum and distal colon by baclofen or GABA.
