If a drug is 50% protein-bound, it means that,
a. 50% of the drug is available
b. 50% less protein should be eaten
c. 50% will pass through the intestines
d. 50% of the drug destroys protein
Answer:
The percentage of drug NOT protein bound is the amount of drug that is free to work as expected. In this case, 50% is unable to be effective, because it is protein-bound. Protein binding has nothing to do with the destruction of protein, drug excretion, or protein in the diet.
