ABSTRACT:
The present invention relates to a method for readily determining the binding site on plasma protein and binding displacement effect of a drug having binding affinity to plasma protein, and application of the method to clinical diagnosis. That is to say, the present invention provides a method for determining the binding site with plasma protein of a first drug, comprising reacting the first drug for which the binding site with plasma protein is to be determined, with a second drug of which the binding site with plasma protein is known and plasma protein, and determining the change in the ratio of the first drug freed due to the binding of the plasma protein with the second drug.
