Common pharmaceutical agents are: Henan Hongdu Pharmaceutical Co., Ltd., Puzhongkang Pharmaceutical Co., Ltd. and Henan Pharmaceutical Co., Ltd. Pharmaceutical agents: not necessarily independent institutions, they do not own the ownership of goods (products/services of the agent manufacturers), they earn commissions (commissions) for a living, and their business activities are guided and restricted by suppliers (that is, investment enterprises), but their supply power is greater. Drug agents are mainly divided into general agents, regional and sub-brand agents, and provincial branches established by general agents themselves. The establishment of agents can share the risks of pharmaceutical production enterprises, so that production enterprises and agents can jointly drive the market, thus reducing the operational risks of production enterprises.
