Antibiotic mechanism of action can be divided into inhibiting the generation of bacterial cell walls, interacting with the cytoplasm, affecting the generation of proteins, inhibiting the transcription of nucleic acids and replication inhibition. 1. Inhibit the generation of bacterial cell wall: inhibit the generation of plant cells will cause bacterial cells to crack and die, with this type of method of efficacy of antimicrobial drugs including amoxicillin capsules, ceftazidime tablets and so on. 2. Interaction with the cytoplasm: some antibacterial drugs interact with the cytoplasm of somatic cells and affect the water permeability of the membrane, which has a fatal effect on somatic cells. Antibiotics that work in this way include mupirocin ointment and picloram tablets. 3. Impact on protein production: Impact on protein production means that enzymes essential for the survival of body cells cannot be produced. Antibiotics that affect protein synthesis include streptomycin tablets, minocycline capsules, and chloramphenicol ointment. 4. Inhibition of nucleic acid transcription and replication inhibition: Inhibition of nucleic acid function blocks cell division or the production of required enzymes. Antibiotics that work in this way include nalidixic acid tablets.
