The Japanese pharmaceutical enterprise: Sanyo Chemical Laboratories Co., Ltd.’s refusal of the NMPA’s inspection was disclosed and exposed by the NMPA on July 31.

If this was the case, it would indirectly show the absolute market share of Yangzhou No. 3 Pharmaceutical in methoxyphenamine hydrochloride variety. Can we check which enterprises use the API of this Japanese enterprise and which en...
