Do not use antibiotics too frequently
Antibiotics have strong efficacy and good therapeutic effects, so many people prefer to use this medicine.
The first is the commonly used products of each generation of antibiotics:
First-generation cephalosporins: Cefalexin, Cefradine, Cefazolin Sodium, Cefadroxil, Cefthiimide, Ceftizole, Cefotaxime
Second-generation cephalosporins: Cefaclor, Cefuroxime, Cefmandole, Cefoxitin
Third-generation cephalosporins:Ceftriaxone sodium, cefoperazone sodium, cefotaxime sodium, ceftazidime, ceftizoxime, cefixime, cefminox, ceftazidime pivoxil, cefdinir
Fourth generation cephalosporins: Cefepime, Cefpiramide, Fluoxef
The difference between the next generations of antibiotics:
I. The first generation of cephalosporins
The first generation of cephalosporins was launched in the early 1960s.
Don't take any medicines indiscriminately
Second and second generation cephalosporins
The antibacterial efficacy of the second-generation cephalosporins against Gram-positive bacteria is similar to or lower than that of the first-generation, while the effects on Gram-negative bacteria are better, as shown in:
1. Strong anti-enzyme property: Some gram-negative bacteria are easily resistant to first-generation cephalosporins.
2. Broad antibacterial spectrum: The antibacterial spectrum of the second generation cephalosporins is expanded compared with the first generation, and it is effective against Neisseria, some indole-positive Proteus, some Citrobacter, and some Enterobacteriaceae
Second-generation cephalosporins are ineffective against Pseudomonas Acinetobacter, Serratia, and Streptococcus faecalis.
Third and third generation cephalosporins
The antibacterial efficacy of the third-generation cephalosporins against Gram-positive bacteria is generally lower than that of the first-generation, and its effect on Gram-negative bacteria is better than that of the second-generation cephalosporins.
1. Expanded antibacterial spectrum: The antibacterial spectrum of the third generation cephalosporins has been expanded compared with the second generation, and it is effective against Pseudomonas aeruginosa, Serratia, Acinetobacter, Peptococcus, and
2. Strong enzyme resistance: For some Gram-negative strains resistant to the first or second generation cephalosporins, the third generation cephalosporins are often effective.
Commonly used are: cefoperazone (Pioneer Bisu), ceftriaxone (Rosezin, bacteria Bizhi), cefotaxime sodium, ceftazidime, ceftizoxime and so on.
Fourth and fourth generation cephalosporins
The third-generation cephalosporins have weak effects on Gram-positive bacteria and cannot be used to control Staphylococcus aureus infections.
