Dicyclomine-d₄  (Synonyms: Dicycloverine-d₄)

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].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
