Pharmacokinetics is an academic field that attempts to understand the mechanisms underlying the fate of drugs in the body after administration, including absorption, distribution, metabolism, and excretion processes. The biomembrane transport is an important factor determining these processes either directly or indirectly. In this article, I would like to introduce how I started my research on membrane transport and how I encountered The Membrane Society of Japan. In addition, as an example of membrane transport research, I will briefly explain the studies on the organic ion transport in the renal tubular epithelial cell membranes and on the kidney–specific accumulation of aminoglycoside by receptor–mediated endocytosis.
