The basic principles of antimicrobial drug use include the following:
Clearly define indications for medication: Antibiotics should not be used indiscriminately. They should only be considered when a bacterial infection is clearly present, and self-medication should be avoided.
Choose appropriate medication: Antibiotics should be precisely selected based on the type of pathogen, the site of infection, and the patient's individual circumstances, such as age, liver and kidney function.
Develop an appropriate dosing regimen: This includes appropriate dosage, route of administration, dosing intervals, and duration of treatment to ensure that the drug reaches an effective concentration in the body, while avoiding overdose or insufficient treatment.
