The difference between the data submitted by five kinds of chemicals to the Food and Drug Administration and innovative drugs

The original drug, that is, the original new drug, was approved for marketing after screening thousands of compounds and strict clinical trials. It takes about 15 years of research and development time and hundreds of millions of dollars. At present, only large multinational pharmaceutical companies have the ability to develop. In China, "original drug" mainly refers to imported drugs that have passed the patent protection period.

"innovative drugs" refers to drugs with independent intellectual property rights, which are a kind of innovative drugs. They make some improvements on the basis of existing drugs, such as structural modification, so that the bioavailability of drugs is higher. Compared with "original drug" and "generic drug", "innovative drug" emphasizes novel chemical structure or new therapeutic use, and can break the patent barrier of "original drug"
