Effect of protein bound on clearance

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.
