Antihemorrhagic

An antihemorrhagic (British English: antihaemorrhagic) agent is a substance that promotes hemostasis (stops bleeding).^[1] It may also be known as a hemostatic (also spelled haemostatic) agent.^[2]

Antihemorrhagic agents used in medicine have various mechanisms of action:

• Systemic drugs work by inhibiting fibrinolysis or promoting coagulation.
• Locally acting hemostatic agents work by causing vasoconstriction or promoting platelet aggregation.
