Ischemia Reperfusion Injury Therapeutics Market: Introduction. Ischemia reperfusion (IR) injury occurs when blood supply, perfusion, and concomitant reoxygenation is restored to an organ or area following an initial poor blood supply after a critical time period.


Ischemia reperfusion (IR) injury occurs when blood supply to part or the whole of an organ is interrupted or drastically reduced. For the kidney, IR is either due to 

The most severe form may lead to primary graft failure and remains a significant cause of morbidity and mortality after lung transplantation. Renal ischemia reperfusion injury is a leading cause of acute kidney injury (AKI), which is still associated with high morbidity, mortality, and increased costs of treatment in both adult and pediatric population 2). FGF23 ameliorates kidney ischemia-reperfusion (IR) injury in mice. Following contralateral nephrectomy, unilateral ischemia and reperfusion (IR) in mice led to gradual increase of blood urea Gastrointestinal Ischemia–Reperfusion Injury. Ischemia–reperfusion of the gastrointestinal tract is associated with a variety of pathologic conditions and surgical procedures, including strangulated bowel, vascular surgery, and hemorrhagic shock. Early reperfusion during MI is critical for saving the myocardium, but it can cause new injury and limit the beneficial effects of reperfusion therapy .

Ischemia– reperfusion injury (I/R injury) refers to a series of pathologic events, which occur after restoration of perfusion to ischemic tissue. While restoration of perfusion is necessary to salvage tissue from the inevitable necrosis, which would otherwise occur, reperfusion can trigger additional tissue injury via free radical injury, programmed cell death, and inflammation.

Oxidative stress is considered a vital factor in I/R injury. Metformin has anti-oxidative properties and protects against I/R injury. Ischemia reperfusion injury is reviewed in the context of the evolution of flap research over the past decade. A description of the clinical relevance of this field is presented and the possible etiologies are reviewed.

Ischemia-reperfusion (IR) injury is directly related to the formation of reactive oxygen species (ROS), endothelial cell injury, increased vascular permeability, and the activation of neutrophils and platelets, cytokines, and the complement system. Several studies have confirmed the destructiveness of the toxic oxygen metabolites produced and their role in the pathophysiology of different Ischemia reperfusion injury is associated with tissue damage and inflammation, and is one of the main factors causing flap failure in reconstructive microsurgery.

Reperfusion injury, sometimes called ischemia-reperfusion injury or reoxygenation injury, is the tissue damage caused when blood supply returns to tissue after a period of ischemia or lack of oxygen. The absence of oxygen and nutrients from blood during the ischemic period creates a condition in which the restoration of circulation results in inflammation and oxidative damage through the induction of oxidative stress rather than restoration of normal function. The term ischemia-reperfusion injury describes the experimentally and clinically prevalent finding that tissue ischemia with inadequate oxygen supply followed by successful reperfusion initiates a wide and complex array of inflammatory responses that may both aggravate local injury as well as induce impairment of remote organ function. Ischemia/Reperfusion Injury (IRI) occurring with ischemia and restoration of blood flow to post-ischemic tissue, is associated with arrhythmias, myocardial necrosis and apoptosis resulting in increased mortality and morbidity.
