Determination of drug or drug metabolite concentrations in biological samples, particularly in serum or plasma, is fundamental to describe the relationships between administered dose, the route of administration, and the time after administration for achieving the optimal clinical response. Rapid metabolism lowers drug exposure at the therapeutic target. Certain types of drug molecules, such as those containing ester or amide-linked groups are prone to enzymatic hydrolysis by plasma esterases, amidases or proteases. On the other hand, enzymatic activation of some prodrugs that takes place in plasma is critical for their function. Hence, plasma enzymes can significantly alter the bioavailability of the active compounds, and therefore determination of the compound stability in plasma has both pharmacokinetic and clinical significance.
