Loperamide reverses signs of mechanical hypersensitivity in an animal model of neuropathic pain suggesting that peripheral opioid receptors may be suitable targets for the treatment of neuropathic pain. Since little is known about loperamide effects on the responsiveness of primary afferent nerve fibers, in vivo electrophysiological recordings from unmyelinated afferents innervating the glabrou...

In the present study, we investigated whether the peripherally acting micro-opioid receptor agonist loperamide would inhibit allodynia in the non-inflamed dermatome of mice with herpetic pain. Subcutaneous (s.c.) injection of loperamide (1 and 3 mg/kg) inhibited allodynia. Local (intraplantar) injection of loperamide (1 and 5 microg/site) also produced an anti-allodynic effect. The peripheral o...

Diarrhea-predominant irritable bowel syndrome (IBS-D) and functional diarrhea (FD) are highly prevalent, and the effectiveness of acupuncture for managing IBS-D and FD is still unknown.The aim of this study was to compare the effectiveness of electroacupuncture with loperamide.It was a prospective, randomized, parallel group controlled trial.A total of 448 participants were randomly assigned to...

The antihyperalgesic properties of the opiate antidiarrheal agent loperamide (ADL 2-1294) were investigated in a variety of inflammatory pain models in rodents. Loperamide exhibited potent affinity and selectivity for the cloned micro (Ki = 3 nM) compared with the delta (Ki = 48 nM) and kappa (Ki = 1156 nM) human opioid receptors. Loperamide potently stimulated [35S]guanosine-5'-O-(3-thio)triph...

1. Morphine suppresses the release of pancreatic polypeptide, a hormone under vagal cholinergic control. The intention of the study was to detect whether the mu-opiate receptor agonist loperamide is also able to inhibit pancreatic polypeptide release, and to define its site of action. 2. In groups of healthy subjects (n = 6 each) stimulation of pancreatic polypeptide was assessed in five differ...

Diarrhea is a common adverse event of docetaxel with 20%-40% of incidence and severe diarrhea occurs in 5%-6%. Several treatment guidelines for chemotherapy induced diarrhea (CID) exist, however the prophylaxis for that is not well known. We describe a new prophylactic approach for the CID with loperamide. A 72-yr-old male patient with stage IV non-small-cell lung cancer developed diarrhea repe...

This study examined the laxative effects of mulberry leaf extract (MLE) fermented by lactic acid bacteria (LAB), which contains high levels of polyphenolic and flavonoid compounds, against loperamide-induced constipation in rats. Sprague-Dawley rats were divided into a normal group (N) and three experimental groups; loperamide treated group (C), loperamide and LAB-fermented MLE 300 mg/kg treate...

BACKGROUND In the airway of subjects with cystic fibrosis (CF) the combination of defective cAMP mediated chloride secretion and enhanced sodium absorption leads to dehydration of mucosal mucus and is reflected in an increased trans-epithelial potential difference (PD). The airway secretions may be less viscid and easier to expectorate if sodium (and water) reabsorption is inhibited. METHODS ...

A total of 315 young children with acute diarrhoea were included in a double blind, hospital based multicentre trial of loperamide at two dose levels (0.8 mg and 0.4 mg/kg/24 h), given with standard oral rehydration therapy versus placebo plus oral rehydration therapy. The overall recovery rate was slowest in the placebo group and fastest in the group given loperamide 0.8 mg. Comparisons betwee...
