Antibacterials in China are now managed at different levels, which are divided into three levels, including unrestricted use, restricted use and special use. Unrestricted drugs refer to antibacterial drugs with good curative effect, strong side effects and bacterial resistance, and low price. Clinicians at all levels can choose according to their needs in the management regulations. Restricted drugs mainly refer to drugs with good curative effect, but with higher price or slightly increased toxic and side effects, or they may be used because of limited bacterial resistance. Super-class antibacterial drugs mean that although they have strong antibacterial effect, they are suitable for the infection of drug-resistant bacteria. Usually, they are clinically used for serious infectious diseases. Strict indications or conclusive evidence are needed when using, and the medicine can only be prescribed after expert consultation or director's consent. The prescription can only be used after it is signed by the deputy director or chief physician. In short, in order to better manage antibacterial drugs, antibacterial drugs in China are divided into three levels: unrestricted use, restricted use and special use.
