Answer: B
Trade name: Usually refers to the final product of the drug, that is, a drug containing one or more active pharmaceutical ingredients with a determined dosage and dosage form. The trade name of a drug is chosen by the pharmaceutical company itself, and like a trademark, it can be registered and applied for patent protection. The trade name of such a drug can only be used by the owner and manufacturer of the drug, and represents the image of the pharmaceutical company and the reputation of the product.
Common name: Also known as the international non-proprietary name (INN), it is the name recommended by the World Health Organization (WHO). INN usually refers to the active pharmaceutical substance rather than the final drug product.
Chemical name: It is named according to its chemical structural formula, with a parent as the basic structure, and then the positions and names of other substituents are marked.
