What is the main action of antifibrinolytic drugs?

To lyse existing blood clots
To prevent the lysis of fibrin and promote clot formation
To increase blood volume
To cleanse the blood of toxins

The correct answer is: To prevent the lysis of fibrin and promote clot formation

Antifibrinolytic drugs work by preventing the breakdown of fibrin, a protein involved in blood clot formation. This biochemical process is crucial in maintaining the integrity of blood clots and preventing excessive bleeding. The other options, while they may indirectly affect blood clotting, do not describe the main action of antifibrinolytic drugs. A) Lysing existing blood clots is not the main action, but rather the opposite effect of these drugs. C) Increasing blood volume may aid in clot formation, but it is not the primary function of antifibrinolytics. D) Cleansing the blood of toxins is not related to the main action of these drugs.
