In 2004, the Ministry of Health issued the Guiding Principles for Clinical Application of Antibacterials, requiring medical institutions to classify antibacterial drugs into three categories: unrestricted use, restricted use and special use according to the characteristics of antibacterial drugs, clinical efficacy, bacterial resistance, adverse reactions, local socio-economic conditions and drug prices, and to clarify the prescription authority of doctors at all levels to use antibacterial drugs.

Clinicians can prescribe antibiotics without restriction according to the diagnosis and the patient's condition. When it is necessary to restrict the use of antibacterial drugs for patients, it shall be approved and signed by a doctor with professional and technical qualifications above the attending physician. If the patient's condition requires special use of antibacterial drugs, it can only be used after being prescribed by a doctor with senior professional and technical post qualifications.

Brief introduction of antibacterial drugs:

Antibacterial drugs generally refer to drugs with bactericidal or bacteriostatic activity, including antibiotics, sulfonamides, imidazoles, nitroimidazoles, quinolones and other synthetic drugs. Some products obtained by cultivating microorganisms such as bacteria, actinomycetes and fungi, or the same or similar substances made by chemical semi-synthesis methods can also be chemically synthesized.
