Abstract
General aspects of drug development are reviewed and problems in modern drug development management are discussed in relation to global networking. Recent changes experienced in drug development have two major factors : innovative technologies derived from basic research, such as genomics, and expansion of global networking in development including clinical trials. The latter is motivated by the need to handle a large amount of data obtained in the process of development utilizing informatics. Another important aspect of modern drug development is strategy that allows timely decision making. Increased investment on drug discovery and globalized clinical studies has resulted in higher risk. The author reviews present circumstances of management in the pharmaceutical companies which have global development systems.
