What are the antibiotics medications?

Antibiotic medications mainly include the following major categories: 1. Penicillins: such as Penicillin G, Ampicillin, Amoxicillin, etc. These drugs exert antibacterial effects by destroying bacterial cell walls. 2. Cephalosporins: such as Cefazolin, Ceftazidime, Ceftriaxone, etc. They also kill bacteria by inhibiting bacterial cell wall synthesis and are characterized by a broad antibacterial spectrum and strong antibacterial activity. 3. Macrolides: including Erythromycin, Azithromycin, Roxithromycin, etc. They are mainly used to treat infections caused by aerobic Gram-positive and Gram-negative cocci, certain anaerobic bacteria, as well as Legionella, Mycoplasma, and Chlamydia. 4. Quinolones: such as Ciprofloxacin, Ofloxacin, Norfloxacin, etc. They achieve inhibition of DNA synthesis by inhibiting bacterial DNA gyrase and belong to fast-acting bactericidal agents.
