Physical barrier at bleeding site

The term "physical barrier at bleeding site" indicates the therapeutic action of certain materials, dressings, or medical devices that, when applied to a wound, create a physical obstruction to blood escape. These barriers, which may be fabricated from natural or synthetic polymers or inorganic materials, support the body’s own hemostatic mechanisms (such as platelet aggregation and clot formation) but do not correspond to a molecular entity, protein, or receptor. This entry is therefore conceptually imprecise and not a molecular target in the conventional sense. Typical examples include surgical hemostatic dressings and sealants whose function is to physically plug or cover wounds and thereby arrest bleeding[2].\n\nThe use of "physical barrier at bleeding site" as a "target" is incorrect within the common molecular-target framework used for drug discovery and development. It instead describes a therapeutic mechanism[2].
