WebBecause warfarin undergoes hepatic metabolism and is highly protein bound, it is particularly prone to drug interactions; in addition, its relatively narrow therapeutic window places patients at risk of either hemorrhagic or thrombotic complications. WebNormally, a high concentration of unbound substance will ensure its removal if it is small and water soluble. Many drugs are bound to plasma proteins (see Chapter 16 ‘How do drugs get into cells?’, p. 126 ). How tightly they are bound then affects how easily they can be removed when they reach the kidneys. cinews weather

WebFrom 97% to 99.9% of warfarin is protein bound, with only a small percentage of the drug free in circulation to exert its biologic effects. As a result, coadministration of other highly protein-bound drugs may displace warfarin from its binding sites, leading to greater amounts of freely circulating warfarin and increased risks of bleeding.
