What is the exclusive formula of medicine? What's the point? What's the difference between patent and patent?

The exclusive prescription of drugs refers to drugs produced by only one pharmaceutical manufacturer. The exclusive prescription of drugs includes: dosage form, dosage, name and other types; Patents have technical content, and varieties have a certain protection period (10 year). In drug bidding, because there are no competing products from different manufacturers of the same variety, exclusive varieties generally have a good price maintenance system, forming a virtuous circle of prices in bidding. In terms of market development, because it is an exclusive variety, it is not limited by one product and two regulations, and there are no similar competitors. As long as this medicine is prescribed in clinic and the corresponding work is done well, it is easy to have better sales.
