Cephalosporins generally refer to cephalosporin antibiotics, which are bactericidal drugs used for the treatment of infectious diseases caused by a variety of sensitive bacteria, such as some pneumonias. The mechanism of action of cephalosporin antibiotics is mainly that they can inhibit the synthesis of bacterial cell walls. They can be used to treat infectious diseases such as pneumonia, biliary tract infection, urinary tract infection, sepsis, bacteremia, meningitis, osteomyelitis and other infectious diseases caused by Staphylococcus aureus, Streptococcus aureus, Pseudomonas aeruginosa and so on. Commonly used cephalosporins include cefuroxime, ceftriaxone, ceftazidime and so on. It should be noted that they can produce gastrointestinal reactions such as vomiting and nausea, phlebitis, allergic reactions and other adverse reactions. Cefuroxime should be contraindicated in cases of cephalosporin allergy. In addition, it is forbidden to drink alcohol during the use of the drug. The use of specific drugs should be carried out under the guidance of a doctor. It is recommended to consult a doctor in time for diagnosis and treatment.
