The national formulary is a guiding document compiled according to the national drug policy, the national standard treatment guidelines and the national essential drug list. It is a professional document used to guide doctors to treat patients reasonably, safely and effectively according to national regulations, and it is also an important document for hospitals to carry out medical management, implement the national essential drug system and implement the national drug policy. Its dosage form should be suitable for the national conditions (disease, medicine and economy) and have strong clinical practicability (different from pharmacology) and authority. Prescription sets should be revised regularly, just like standard treatment guidelines and lists of essential drugs.
