Displacement of binding with plasma proteins
As noted above, warfarin is highly bound to proteins
(primarily albumin) in the plasma and has
the potential for interactions with other highly
protein-bound substances. The effect is usually
transient and the clinical significance may be questionable.
7 This type of interaction is probably more
significant in the presence of an enzyme inhibitor,
because the body is unable to compensate by
increasing the metabolism of the higher free fraction
of the displaced drug.
