Urgent ... I ordered medicine for skin diseases online. It is on the medicine bottle. The national application patent number is 200700628. Is it edible? Is it fake?

That must be a lie. First of all, the patent number is not 9 digits and should not be 0 after 2007. It should be 1 or 2. If you want to further confirm it, just check China National Intellectual Property Administration, which can be found on Baidu. Searching for the patent number or drug name is definitely fruitless.
