Prothrombotic agent used for minor to moderate bleeding such as during dental procedures?

• A. Vitamin K2
• B. Tranexamic Acid
• C. Aprotinin
• D. Aspirin

Answer: (B)

Controlling minor to moderate dental bleeding often relies on drugs that stabilize formed clots by blocking their breakdown. Tranexamic acid is an antifibrinolytic, meaning it prevents plasmin from dissolving clots. By inhibiting this fibrinolysis, existing clots stay intact longer, which reduces bleeding during dental procedures. It can be used systemically or as a mouth rinse, making it a practical choice for patients with bleeding risks or those on anticoagulants.

Vitamin K2 helps activate clotting factors, supporting the coagulation cascade, but it isn’t the fast-acting option typically used to manage acute minor dental bleeding. Aprotinin inhibits enzymes that break down clots, and while it can reduce bleeding in some surgeries, it’s not commonly used in dentistry due to safety and practical considerations. Aspirin, on the other hand, impairs platelet function and tends to worsen bleeding, so it’s not suitable for stopping bleeding in these cases.
