Drugs invented by oneself may not be produced by themselves. According to China's food and drug supervision and management regulations, the production of drugs requires exclusive license and special license. Only after obtaining the production license can you enter the production process, production and sales. If you only have medical patents, you can consider cooperating with pharmaceutical manufacturers to make dividends or shares.
If the production and operation license is obtained, it can of course be promoted. But the promotion of drugs is also different from the special rules of other commodities.
I hope my answer can help you!
