How are anticoagulants and fibrinolytic agents different?
A. Fibrinolytics and anticoagulants both thin the blood to prevent clot formation.
B. Fibrinolytics are taken orally and anticoagulants can only be given parenterally.
C. Anticoagulants inhibit blood clot formation and fibrinolytics degrade existing clots.
D. Anticoagulants work by interfering with clotting factor synthesis and fibrinolytics work by disrupting platelet aggregation.
C
Anticoagulant drugs exert their effects by interfering with one or more steps involved in the blood-clotting cascade. Thus, these agents prevent new clots from forming and limit or prevent extension of formed clots, but have no degradative effects on existing clots. Fibrinolytic drugs selectively degrade fibrin threads already present in the formed blood clot.
