Pharmacodynamics, Pharmacokinetics, Safety, and Tolerability of Encenicline, a Selective α7 Nicotinic Receptor Partial Agonist, in Single Ascending-dose and Bioavailability Studies

Abstract

Encenicline was well tolerated at single doses up to 180 mg, and doses as low as 1 mg had dose- and time-dependent pharmacodynamic effects on the central nervous system. Oral capsule and solution were bioequivalent and were not affected by food. Although a sex effect on pharmacokinetic profile was observed, it was attributable to weight differences.
