Same mechanism of action, 40-50 times more potent than morphine in reducing gut motility. Differences With Diphenoxylate. It is concluded that both difenoxin and loperamide inhibit net fluid secretion by indirect mechanisms. It is proposed that the initial action is on enteric μ-opiate receptors and that this results in the release of 5-HT. In the case of difenoxin, the 5-HT may act on 5-HT 1-like receptors to release noradrenaline. However, the major difference

Rosalind Dalefield BVSc PhD DABVT DABT, in Veterinary Toxicology for Australia and New Zealand, 2017. Loperamide. Loperamide is a weak opioid used as an antidiarrheal agent in human beings and dogs, and is sometimes used in cats although it may cause excitement in cats.. Toxicity may occur in dogs, usually as a result of consuming large quantities of loperamide formulated for human use. Mechanism of action Loperamide binds to the opiate receptor in the gut wall, reducing propulsive peristalsis, increasing intestinal transit time and enhancing resorption of water and electrolytes. Loperamide increases the

Opioids increase the tone and decrease the propulsive contractions of the smooth muscle of the gastrointestinal tract. Prolongation of the gastrointestinal transit time may be the mechanism of the constipating effect.
