Drugs Coordinating and Restoring Gastrointestinal Motility and their Effect on Selected Hypodynamic Gastrointestinal Disorders in Horses and Cattle Academic Article uri icon

abstract

  • Hypodynamic gastrointestinal disorders in horses and cattle that are thought to benefit from treatment with drugs restoring and coordinating gastrointestinal motility include postoperative ileus and large colon impaction in the horse and displacement of the abomasum and dilatation of the cecum in cattle. Important physiologic, pathophysiologic and pharmacologic mechanisms involved in the intrinsic control of gastrointestinal motility include cholinergic, adrenergic, dopaminergic, serotoninergic, and opioid‐mediated pathways. Preliminary results suggest that cisapride, acting on 5‐Hydroxytryptamine receptors, might be useful for treatment of idiopathic postoperative ileus and the α2‐adrenoceptor blocking agent yohimbine for endotoxic postoperative ileus. Naloxone, an opioid antagonist, and neostigmine, an acetylcholinesterase inhibitor, are thought to restore motility of the large colon in cases of large colon impaction in the horse. Bethanechol and neostigmine significantly increase myoelectric activity of the cecum and proximal loop of the ascending colon in healthy cows. Investigations of the effects of prokinetic drugs on displacement of the abomasum of cattle do not allow any conclusions because no results derived from controlled experimental disease models are available. © 1995 Blackwell Verlag GmbH
