WebDrug–protein binding may vary from 0% (eg, lithium) to 99% (eg, ketorolac), and it is only the unbound drug (free drug) that is pharmacologically active. Albumin is the major drug-binding protein in the serum, although other proteins, such as α1acid glycoprotein, lipoproteins, and globulins, are also capable of binding drugs. WebOne example of this in pharmacology is the use of glucocorticoids like prednisone, which bind the glucocorticoid nuclear receptor and decrease the production of pro …
