The pharmacokinetics and metabolism of SNI-2011 ((+/-)-cis-2-methylspiro[1,3-oxathiolane-5,3'-quinuclidine]monohydrochloride hemihydrate, cevimeline, CAS 153504-70-2), a novel muscarinic acetylcholine receptor agonist developed for the treatment of Sjögen's syndrome, were investigated in six healthy volunteers after a single oral administration of 14C-SNI-2011. After administration, plasma concentrations of the radioactivity and SNI-2011 reached to Cmax at approximately 2 h, and then decreased with t 1/2 of 9 and 4 h, respectively. Cmax and AUC0-infinity of the radioactivity in plasma were 2.

In this study, the pharmacokinetics of SNI-2011 ((+/-)-cis-2-methylspiro[1,3-oxathiolane-5,3'-quinuclidine]monohydrochloride hemihydrate, cevimeline, CAS 153504-70-2), a novel muscarinic acetylcholine receptor agonist developed for the treatment of Sjögren's syndrome, in rats and dogs were determined following intravenous or oral administration using liquid chromatography/mass spectrometry (LC/MS). The in vitro metabolism of SNI-2011 was also evaluated with rat and dog liver microsomes. After oral administration, plasma concentrations of SNI-2011 reached to Cmax within 1 h in both species, suggesting that SNI-2011 was quickly absorbed, and then decreased with a t1/2 of 0.
