There is no argument that drugs are better than anyone else, and the therapeutic effect of antimicrobial drugs is related to the causative organism, the patient’s physical condition, the severity of the disease and other factors. Clindamycin mainly inhibits bacterial protein synthesis, and its antibacterial spectrum includes aerobic gram-positive cocci and anaerobic bacteria. Cephalosporins mainly affect the synthesis of the cell wall, the third and fourth generation drugs belong to the broad-spectrum antibacterial drugs. Clindamycin can lead to allergic reactions, such as rash, urticaria, etc.; it can also lead to gastrointestinal reflections, manifested as nausea and vomiting, abdominal pain and diarrhea, etc.; it can also cause abnormalities in liver and kidney function. Note that patients who are allergic to the product or have a history of allergy are prohibited. Cephalosporins can cause allergic reactions, so skin test is required before use, and positive reactions are prohibited. Prolonged use of large quantities can lead to secondary infections. Patients should use the drug under the guidance of a professional physician, do not give the drug without authorization.
