Effect of drugs with various mechanisms of action on propulsive activity of the small intestine

Abstract

We studied the effect of drugs with various mechanisms of action on propulsive activity of the small intestine in healthy rats. Blockade of the major inhibitory influences realized via nonadrenergic noncholinergic inhibitory effector neurons was not followed by stimulation of intestinal transit. Propulsive activity of the small intestine increased upon treatment with drugs, whose effects are realized via acetylcholine or acetylcholine and serotonin.
