With the continuous progress in medical science and technology, drug evaluation criteria in China are also changing and improving. In the past, drug evaluation criteria did not require generic drugs to have the consistent quality and efficacy of innovator drugs; so some had a gap in efficacy. Since 2015, the National Medical Products Administration of China (NMPA), formerly the China Food and Drug Administration (CFDA), rolled out the Generic Quality and Efficacy Consistency Evaluation (GQEC) to improve the quality and efficacy of generic drugs. Generic drugs whose quality and efficacy are deemed equivalent to innovator drugs will enjoy preferential treatment in public hospitals and prescriptions.
