Then, at present, international drug production can be declared to relevant international organizations (such as the relevant agencies of the World Health Organization) after drug research and development is completed, and production protection can be obtained. The general protection period is about 10 year. In fact, as long as the drugs are listed, their main components are basically open. However, due to the protection period, other pharmaceutical companies must pay fees to R&D manufacturers if they want to produce, and R&D manufacturers can refuse applications from other manufacturers if they want to maintain their monopoly position. However, because it is in the market protection, it is often expensive in pricing, which ensures that R&D manufacturers have a lot of profit space.
