Description : Cevimeline hydrochloride hemihydrate is a novel and selective agonist of muscarinic acetylcholine receptor [1]. Muscarinic acetylcholine receptors (mAChRs) are acetylcholine receptors and mediate serous-saliva secretion and tear secretion. It is more sensitive to muscarine than nicotine [1]. Cevimeline hydrochloride hemihydrate induced contractions of isolated guinea pig ilea and trachea with EC50 values of 3.5 and 3 M, respectively. Binding studies indicated that Cevimeline hydrochloride hemihydrate was a potent and highly selective M1-type muscarinic agonist. Also, it had a higher affinity for M1 receptors than other M1 agonists [2]. In normal rats and mice, X-irradiated saliva secretion defective rats and two strains of autoimmune disease mice, intraduodenal administrations of SNI-2011 (3-30 mg/kg) increased saliva and tear secretions in a dose-dependent way, which suggested that Cevimeline hydrochloride hemihydrate directly stimulated muscarinic receptors in salivary and lacrimal glands for saliva and tear secretions [1].References:[1].
