Effect of KW-5092, Novel Gastroprokinetic Agent, on the Peristalsis in the Isolated Guinea Pig Ileum

摘要

References(12) We examined the effect of KW-5092, a gastroprokinetic agent with acetylcholinesterase inhibitory and acetylcholine release facilitatory activities, on the peristalsis of isolated guinea pig ileum. KW-5092 (10-9-3 × 10-6 M)increased the frequency of the peristaltic wave without changing its amplitude. Neostigmine increased the frequency at 10-7 M, but domperidone (10-8-3 × 10-6 M)had no effect on the peristalsis. The present results suggest that KW-5092 enhances the peristalsis via the inhibition of acetylcholinesterase, resulting in the intestinal propulsion.
