Abstract: Clonidine (0.01 to 0.16 mg/kg) and lofexidine (0.01 to 0.64 mg/kg) produced a dose‐dependent inhibition of diarrhea induced by castor oil treatment in the rat. Both drugs were more potent and longer acting than diphenoxylate. Pre‐ and posttreatment with naloxone (5 mg/kg) failed to prevent or antagonize the antidiarrheal effect of clonidine and lofexidine. These data suggest that clonidine and lofexidine may provide potent antidiarrheal activity of a nonnarcotic nature. 
Studies of the antidiarrheal action of clonidine
Abstract Clonidine, an α 2 -adrenergic agonist, has been reported to stimulate the rate of electrolyte absorption in vitro, to alter intestinal motility in vivo, and to have antidiarrheal effects inExpand
Effectiveness of lofexidine in blocking morphine-withdrawal signs in the rat
TLDR
The data suggest that lofexidine, like clonidine, may reduce the narcotic withdrawal syndrome in humans. Expand
Studies of the antidiarrheal action of clonidine. Effects on motility and intestinal absorption.
TLDR
It is indicated that in this experimental diarrhea model, clonidine has antidiarrheal properties that are due largely to effects on motility of the gut but thatClonidine also modestly stimulates the net rate of absorption by intestinal mucosa. Expand
Effectiveness of Nantradol in Blocking Narcotic Withdrawal Signs Through Nonnarcotic Mechanisms
TLDR
Nantradol failed to produce any generalization to morphine, cyclazocine, or clonidine, suggesting that this drug does not produce central subjective effects like those of the training drugs, and in additional testing in behavioral experiments, nantradl failed to production any sign of anxiogenic activity.

Suppression of small intestinal motility and morphine withdrawal diarrhoea by clonidine: peripheral site of action.
TLDR
It is concluded that the potent inhibition of small intestinal myoelectric activity by alpha 2-adrenoceptor agonists is mainly executed via peripheral mechanisms, which may contribute to their beneficial action in morphine withdrawal diarrhoea, and partly underlie a general antidiarrhoeal action.

Antagonism of the antidiarrhoeal effect of clonidine and the lethal effect of noradrenaline in rats: a reliable procedure to evaluate the in‐vivo α1‐ and α2‐blocking activity of drugs?
TLDR
Results show that yohimbine and RX781094 are equipotent and relatively selective alpha 2-antagonists; piperoxan and phentolamine block both alpha 1- andalpha 2-receptors at closely related doses. Expand
Naloxone‐induced reversal of clonidine, but not hydralazine, hypotension
TLDR
It is suggested that naloxone's antagonism of clonidine hypotension is located at a central nervous system site, and that clonazine hypotension may be mediated through an interaction with the brain opiate systems. Expand
Further support for the central origin of the gastric antisecretory properties of clonidine in conscious rats.
TLDR
The results confirm that the CL inhibition of the gastric acid secretion in unanesthetized rats is mediated at least partly through the stimulation of alpha 2-adrenergic receptors and suggest the possibility that most of the receptors involved are located in the medulla oblongata. Expand
Antidiarrheal therapy
TLDR
Present and proposed antidiarrheal agents, in addition to antimotility activity, will be capable of stimulating intestinal fluid absorption, inhibiting intestinal fluid secretion, or both. Expand
Effect of antisecretory drugs on experimentally induced weanling diarrhoea in piglets
TLDR
In 45 newly-weaned 3 to 4-week-old piglets, diarrhoea was induced by a combined infection with transmissible gastroenteritis (TGE) virus and enterotoxigenic E. coli (ETEC) strains and α2 agonist clonidine induced a significant antidiarrhoeal effect and a reduction in mortality. Expand

TLDR
A definitive placebo response was perceivable in the decreasing of symptoms and the effect of clonidine did not differ significantly from placebo effect in the treatment of the symptoms. Expand

TLDR
Radioisotope studies indicate an increase in noradrenaline storage without significant changes in metabolism in rats and guinea‐pigs, and at doses causing similar conditioned avoidance response inhibition produced a significant increase in Noradrenalin concentration in all brain regions except the striate.
