Both in vitro and in vivo preclinical investigations to assess the any clinical outcomes prior to drug launch are taken into account to reveal the potential of DDI and its mechanism of any drug under development. Evaluation of the possible interactions of a drug candidate with other drugs as soon as possible—not only as an inhibitor or inducer (perpetrator) but also as a substrate (victim)—could avoid detrimental DDIs in humans. As will be discussed later, DDIs represent a major mechanism of adverse drug reactions, and consequently their evaluation is critical to studies within all the drug development stages, drug discovery, and regulation of new drug candidates to avoid any serious toxicity that leads to drug withdrawal postmarket. Finally, the ultimate goal of nonclinical and clinical DDI studies is to permit integration of DDI knowledge acquired in the development phase into prescribing guidance in a manner that enables optimal postmarketing risk management following marketing authorization. Not all the preclinically determined DDIs can be considered as clinically significant (poor correlation between in vitro and in vivo observation).
