How to apply for a patent for drug invention

First of all, you need to consult the Pharmacopoeia to see if there is a drug containing the ingredients you invented, and then you can consult the State Patent Office on how to apply for a patent for drug invention. It is relatively easy to apply for patents on other things, but the life of drugs is crucial. I'm afraid it can only be recognized as a newly invented effective drug after strict inspection and crowd test by relevant departments. Probably not as a scientific and technical person who specializes in drugs, no one accepted the inspection. If it can be linked to pharmaceutical research units, it may be easier to obtain patents by introducing it to the patent office.
