The newly revised “Drug Administration Law” officially took effect on December 1st，2019. This revision of the “Drug Administration Law” put forward several measures to encourage research and development innovation and ensure the accessibility of drugs. The most prominent was that the concept underlying the “Drug Administration Law” covered the control throughout the whole process，and full life cycle safety supervision and guarantee. This new version had twelve chapters，two more chapters than the previous version. The most significant change was listing Marketing Authorization Holder（MAH）and post-marketing management of drugs in separate chapters，showing the importance of both.
