The management of antimicrobial agents in three categories is mainly to strengthen the clinical application management of antimicrobial agents in medical institutions, standardize the clinical application behavior of antimicrobial agents, improve the clinical application level of antimicrobial agents, promote the rational clinical application of antimicrobial agents, control bacterial resistance, and ensure medical quality and medical safety.

The hierarchical management of antibacterial drugs is divided into three levels: ① unrestricted use level. ② Restrict the use level. ③ Special use level. Prescription must be signed by a doctor with the title of deputy high school or above before use.

Antibacterials commonly used in clinic

1. Cephalosporins. Cephalosporins can be divided into first generation cephalosporins, second generation cephalosporins, third generation cephalosporins, fourth generation cephalosporins, etc. Different cephalosporins have different antibacterial spectra, so it is necessary to select drugs according to specific conditions, such as cefalexin and ceftazidime.

2. Penicillins, including common penicillins and broad-spectrum penicillins, such as amoxicillin and ampicillin, belong to broad-spectrum penicillins.

3. Quinolones, such as levofloxacin and moxifloxacin, are commonly used.

4. Macrolides, including azithromycin and roxithromycin.

5. Other kinds of antibiotics, such as carbapenem antibiotics and aminoglycoside antibiotics.

To sum up, there are many kinds of antimicrobial agents, and different antimicrobial agents have different characteristics. Therefore, they should be used under the guidance of doctors to avoid abuse of antimicrobial agents and induce bacterial resistance.
