This article analyzed the current regulatory situation of FDA on complex generic drugs (nonbiological complex drugs) from two aspects: First, the feasibility of technical evaluation of pharmaceutical equivalence and bioequivalence of complex generic drugs; second, FDA's response strategy to the doubts and challenges of complex generic drugs. The complex generic drugs defined by the FDA contain natural-sourced complex drug substances. The article summarized the FDA's measures using regulatory science to vigorously promote scientific research when facing scientific challenges of complex generic drugs. The methods of promotion include formulating scientific research plans, identifying key research areas, setting up topics, summarizing annual scientific research results, and strengthening communication with the industry. The thoughts of FDA on complex generic drugs may be used as a reference for the technical evaluation of traditional Chinese medicines with the same name and same prescription.
