Abstract:Pain is both a protective response necessary for the survival of the species and a global health issue that affects human health and social development. In the next decade, China will become the largest and fastest growing pain treatment market in the world. Pain elimination is a major demand of scientific and technological innovation for the people's life and health and the national health strategy. Finding new analgesic targets and developing new analgesic strategies have become the frontier scientific issues of international scientific research. This paper briefly reviewed the classification of pain and its treatment status, focused on the research progress of analgesic strategies and molecular targets, and discussed the possible development directions in the field of pain and analgesia.
