What best describes how Arista AH functions?

• A. It dissolves clots by enzymatic action.
• B. It acts systemically to stimulate coagulation factors.
• C. It acts locally at the bleeding site to assist hemostasis, not a systemic effect.
• D. It enhances platelet aggregation systemically.

Answer: (C)

Arista AH works by providing a local hemostatic scaffold at the bleeding surface. When applied, it interacts with the blood at that site to concentrate platelets and clotting factors and support fibrin clot formation right where the bleed is, accelerating hemostasis. Its effect is confined to the local area; it does not trigger systemic coagulation or platelet activation throughout the body. It’s applied topically and is eventually absorbed as healing progresses. That local, site-specific action is why it’s described as acting locally at the bleeding site rather than having a systemic effect.
