Abstract
Trends and future perspectives in drug delivery research are discussed. Recently research on movement and fate of various compounds including drugs attracts great interest not only in the field of therapeutics but also in all fields of life science. In order to elucidate and control in vivo fate of drugs, its disposition features should be analyzed based on a pharmacokinetic model. Based on obtained information about relationship between physicochemical and biological properties of drugs and their in vivo disposition, total performance of drugs in the body can be controlled deductively. Progress in drug delivery technology would develop new era in medicine.
