Mechanism

Racecadotril is a prodrug that is rapidly converted to its active metabolite, thiorphan, an enkephalinase inhibitor. Thiorphan prevents the degradation of endogenous enkephalins, which in turn reinforces their effects on delta-opioid receptors to inhibit intestinal secretion, thereby producing an anti-diarrheal effect.
