Dicyclomine-d4 is the deuterium labeled Dicyclomine[1]. Dicyclomine (Dicycloverine) is a potent and orally active muscarinic cholinergic receptors antagonist. Dicyclomine (Dicycloverine) shows high affinity for muscarinic M1 receptor subtype (Ki=5.1 nM) and M2 receptor subtype (Ki=54.6 nM) in brush-border membrane and basal plasma membranes, respectively[2]. Dicyclomine is an antispasmodic agent and relieves smooth muscle spasm of the gastrointestinal tract in vivo[3].
