Vascular response modulator

Vascular response modulator is a functional classification rather than a specific molecular target or receptor. It refers to a broad group of therapeutic agents that influence the physiological behavior of blood vessels, particularly in response to inflammation, injury, or stimuli. In clinical pharmacology, the term is most prominently associated with proteolytic enzymes such as trypsin and chymotrypsin, which are described as modulating the vascular response to minimize necrotic damage, reduce edema, and promote tissue repair by clearing fibrin-blocked microcirculation. These agents are thought to work by regulating the levels of acute-phase reactants and facilitating the resolution of inflammatory exudates. In other therapeutic contexts, such as sexual health, the term may refer to vasoactive substances like sildenafil or alprostadil that regulate blood flow and vascular tone. Because it describes a physiological effect rather than a single protein or gene product, it is considered a functional category of therapeutic action.
