Naloxone, a versatile opioid receptor antagonist, is widely used in clinical rescue of acute intoxication events. Studies have shown that naloxone can exert myocardial protective effects by activating the Fas FasL receptor and MAPK signaling pathways, reducing the myocardial cell death rate and the degree of myocardial tissue fibrosis.This article intends to conduct comprehensive research on the mechanism of naloxone in myocardial I/R injury, and explore the molecular mechanism of naloxone exerting myocardial protective effects by activating the Fas FasL and MAPK signaling pathways, in order to provide effective treatment strategies for clinical rescue of myocardial ischemia-reperfusion injury.
