… From [Anticonvulsants]...A drug that relaxes abnormal contractions and spasms of visceral smooth muscles and relieves visceral pain caused by spasms. It is broadly divided into two types. One is a parasympathetic nerve suppressant (anticholinergic drug) represented by atropine, which is also called neurotropic antispasmodic or atropine-like agent. It inhibits and antagonizes acetylcholine, blocking the transmission of nerve excitation and relieving spasms. The other is a drug that acts directly on smooth muscle cells to suppress spasms, and since papaverine is a typical example of this drug, it is also called neurotropic antispasmodic or papaverine-like agent. *Some of the terminology explanations that mention "atropine-like drugs" are listed below.
