Since the Drug Administration Law was promulgated in 1984, the drug safety surveillance has been established and gradually improved in China through for example the following measures: 1. Temporary Regulation for Monitoring Adverse Drug Reactions promulgated in November 1999; 2. Revision of national standards of drugs; re-evaluation and revocation of licenses of drugs that do not reach standards on safety and efficacy; 3. China joined CIOMS (Council for International Organizations of Medical Sciences) under the WHO (World Health Organization) in 1998.
