Ciclotropium (free base) is quaternary ammonium compound with anticholinergic and parasympatholytic activity. Oral Cyclotropium bromide inhibited fasting and meal-stimulated colonic motility significantly without causing adverse side effects. After cyclotropium bromide, there was a significant correlation between antral contraction amplitude and gastric emptying.
Acotiamide Methyl Ether is a metabolite of Acotiamide -- an acetylcholinesterase inhibitor which has been shown to stimulate gastricmotility and improve gastricmotility dysfunction in rats. Acotiamide Hydrochloride has also been shown to improve meal-related symptoms of functional dyspepsia.
