Final answer:
Warfarin is an anticoagulant that binds to albumin in the blood. If albumin levels are low, it can lead to increased levels of free warfarin, which may increase the risk of bleeding.
Step-by-step explanation:
An anticoagulant is a substance that opposes coagulation. Warfarin is an example of an anticoagulant and it works by inhibiting the synthesis of vitamin K-dependent clotting factors. It has a high affinity for binding with albumin, a protein found in the blood. If albumin levels are low, it can lead to increased levels of free warfarin in the blood, which may increase the risk of bleeding.
