Large foreign pharmaceutical factories are often the original research and development units of this drug, while domestic enterprises are imitation products developed after the protection period of foreign products. The development of real "new drugs" needs chemical synthesis and the application of pharmacodynamic zoology.
Multi-phase clinical trials, multiple reviews and approvals, consume huge manpower and material resources. The cost of developing new drugs is usually more than "100 million" dollars, but for generic drugs, the investment is much smaller because of the established products and clinical data. Millions of RMB can be used as a generic drug, so the original drug is expensive.
Extended data:
It is usually related to the huge investment in drug research and development, while the investment in generic drugs is small and the price is relatively low. Of course, even generic drugs, products produced by different companies have certain price differences, which are often not too big.
Generally, it is related to the cost control, pricing strategy and national policy of manufacturers. Although the original drug is very different from the generic drug, there is no difference in the main components of the drug.
However, because the original research products have invested a lot of money in drug research and clinical data collection, the original research products are the most adequate in terms of the adequacy of drug research, and often have certain advantages in quality and efficacy.
