Because pharmacology seeks to understand therapeutic effects in the whole body and in human populations down to the pharmacological effects that occur at the molecular level, pharmacology integrates basic and clinical applications. Only when the quality of both the test substance and the biological model is stable can we understand the mechanism of pharmacological action leading to a cure. Thus, quality assurance of both the test substance and the biological model is highly important to collect pharmacological data successfully with high reproducibility and reliability among different laboratories. However, the survey about the lectures on quality assurance of foods and pharmaceuticals introduced by Dr. Goda’s talk revealed that education on quality assurance was lacking even though some topics are covered in pharmacology lectures. In this talk, I would like to discuss with audience how to improve education on quality assurance in pharmacology education by citing several cases where the concept of quality assessment is important in pharmacological research.
