A narrow range exists where the benefits of warfarin are greater than the risks, its therapeutic window. Certain drugs, herbal medicines, and foods can interact ...
For example, the "fraction bound" of the anticoagulant warfarin is 97%. This means that out of the amount of warfarin in the blood, 97% is bound to plasma proteins. The remaining 3% (the fraction unbound) is the fraction that is actually active and may be excreted. Protein binding can influence the drug's biological half-life. The bound portion ...
