説明
Racecadotril, also known as acetorphan, is a kind of antidiarrheal drug acting as a peripherally acting enkephalinase inhibitor. It belongs to the group of gastrointestinal drugs and is also a lipophilic derivative of Thiorphan. Racecadotril is a dipeptide in which there is a single amide bond. It has an antisecretory effect, reducing the secretion of water and electrolytes into the intestine. Racecadotril is a pro-drug that is metabolized in vivo into the active compound, thiorphan. Thiorphan exerts its inhibitory effect on enkephalinase, reducing the amount of secreted water produced by the intestines. In this case, the body loses less fluid, and the symptoms of diarrhea can be alleviated.

White Solid
使用
Racecadotril is an enkephalinase inhibitor that prevents the degradation of endogenous opioids. It demonstrates antidiarrheal activity by reducing hypersecretion of water and electrolytes into the intestinal lumen. It is an effective and safe treatment for acute diarrhea in adults and children.
定義
ChEBI: Racecadotril is a N-acyl-amino acid. It is a pro-drug that is metabolized in vivo into the active compound, thiorphan. It has been investigated for the basic science and treatment of Diarrhea, Acute Diarrhea, and Acute Gastroenteritis.
臨床応用
Racecadotril(Acetorphan, 81110-73-8) is an anti-secretory drug that has been used for acute diarrhoea in children as an adjunct to oral rehydration therapy. It displays antidiarrheal activity via a purely antisecretory mechanism without inhibiting intestinal transit.
副作用
Racecadotril may cause headache, drowsiness, fever, nausea and vomiting. Besides, in special cases, there may be rare side effects such as rash, erythema, acne skin, urticaria, erythema multiforme, tongue edema, face edema, eyelid edema, angioedema.
合成
Benzaldehyde and diethyl malonate were combined, reduced, and hydrolyzed
to form benzyl malonic acid. This acid was then reacted with
paraformaldehyde and diethylamine to produce benzyl acrylic acid.
Thioacetic acid was then added to this compound, and it was condensed
with benzyl glycinate p-toluenesulphonate to obtain racecadotril. Overall, the process had a yield of 66%.
Mode of action
Acetorphan acts as rapidly as loperamide, a classical muopiate receptor agonist that exhibits its antidiarrheal effect via an antitransit mechanism, without producing constipation or other side effects. The novel mechanism of action may render acetorphan potentially useful in the management of infectious diarrhea.
