Pharmacology of Hematopoietic Drugs: Mechanisms and Clinical Applications

1. What is the mechanism of action of warfarin?

Warfarin works by increasing the production of clotting factors

Warfarin acts by directly inhibiting platelet aggregation

Warfarin functions by activating antithrombin III

Warfarin inhibits the synthesis of vitamin K–dependent clotting factors X, IX, VII, and II, which is different from the incorrect answers provided.

Explanation

Warfarin inhibits the synthesis of vitamin K–dependent clotting factors X, IX, VII, and II, which is different from the incorrect answers provided.

2. How do anticoagulants like Heparin work?

Anticoagulants work by increasing blood clotting factors.

Anticoagulants work by directly dissolving blood clots.

Anticoagulants work by activating platelets to prevent clot formation.

Anticoagulants, like Heparin, work by binding with antithrombin II and inactivating specific factors involved in the clotting cascade.

Explanation

Anticoagulants, like Heparin, work by binding with antithrombin II and inactivating specific factors involved in the clotting cascade.

3. What type of medication is Rivaroxaban?

Heparin is a type of antidepressant medication.

Rivaroxaban is an oral medication that acts as a factor XA inhibitor

Aspirin is a type of anticoagulant medication that inhibits platelet aggregation.

Warfarin is an anticoagulant that acts by inhibiting vitamin K epoxide reductase.

Rivaroxaban is a direct factor Xa inhibitor that works by blocking the activity of factor Xa, a key component in the blood coagulation cascade. This mechanism prevents the formation of blood clots.

Explanation

Rivaroxaban is a direct factor Xa inhibitor that works by blocking the activity of factor Xa, a key component in the blood coagulation cascade. This mechanism prevents the formation of blood clots.

4. How do antiplatelet drugs work?

Antiplatelet drugs work by inhibiting the action of thrombin.

Antiplatelet drugs primarily target white blood cells instead of platelets.

Antiplatelet drugs increase platelet aggregation by stimulating adenosine diphosphate (ADP) pathways.

Antiplatelet drugs work by disrupting specific pathways involved in platelet aggregation, reducing the risk of clot formation.

Explanation

Antiplatelet drugs work by disrupting specific pathways involved in platelet aggregation, reducing the risk of clot formation.
