What are the three generations of cephalosporin? What are the three generations of imported cephalos

The main ones are as follows:

Cefotaxime (Keflon), ceftriaxone.

Bacterium), ceftazidime (fudaxin), cefdizime (Modi), cefoperazone (Pioneer), cefmethoxime (Anjiejian), cefazoloxime, cefixime.

Sefusu), cefbrune, cefdinir, ceftoran, etc.

Notes:1Some medicines are named in parentheses as aliases or colloquial names.

2.Among the above 11 drugs, the first 7 are generally injections, and the last 4 are oral preparations (ceftor is generally made into ceftor pirate tablets).

3.Among the above drugs, cefotaxime has the strongest antibacterial activity against Enterobacteriaceae, and ceftazidime has the strongest antibacterial activity against Pseudomonas aeruginosa.

The antimicrobial activity is the strongest.

4.Ceftriaxone is the only long-acting formulation of the above drugs, and cefdizime is the only drug with immunomodulatory effects.

Cefixime Cefotaxime.

Ceftriaxone (bacterium must be cured).

Ceftazidine (Fudaxin).

Cefoperazone (Pioneer Benzin).

Ceftazimidoxil.

Cefminol sodium.

Characteristics of the application

1.It is strong against anaerobic bacteria and gram-negative bacteria, and (including Pseudomonas ketoaeruginosa) has less effect on Germa.

1st and 2nd generation. 2.More stable to B-endosaminese.

3.It is basically non-toxic to the kidneys.

4.It is mainly used for serious infections caused by sensitive bacteria such as urinary tract, pneumonia, meningitis, sepsis and Pseudomonas aeruginosa infection. Among them, "cephatadine" currently acts on the strongest antibiotic against Pseudomonas aeruginosa.

The third generation of cephalosporins: characteristics, wide antibacterial spectrum, strong antibacterial effect, more stable against B-lactamase, and far more effective against G-bacteria.

The first and second generation cephalosporins are strong, and the effect on G+ is slightly weaker.

The first and second generation cephalosporins have certain antibacterial activity against Pseudomonas aeruginosa, and they have a certain antibacterial activity against Pseudomonas aeruginosa.

Some strains resistant to first- and second-generation cephalosporins remain effective.

Commonly used are: cefoperazone (vanguard), ceftriazine (rosetin, bacterium), cefotaxime sodium, ceftazidime, cefazoloxime, etc.

1. Generic name: ceftazidime for injection, English name: ceftazidimeforinjection, trade name: Fudaxin, manufacturer: .

Ceftazidime for injection, this product can be used for sepsis, lower respiratory tract infection, abdominal biliary infection, complicated urinary tract infection and severe soft tissue infection caused by sensitive gram-negative bacilli. It is particularly useful for immunocompromised infections caused by multiple resistant gram-negative bacilli, nosocomial infections, and central nervous system infections caused by gram-negative bacilli or Pseudomonas aeruginosa.

2, generic name: ceftazidime for injection, English name: ceftazidimeforinjection, trade name: Kaifuding, manufacturer: antibioticosdobrasilltda.

Caused by Pseudomonas aeruginosa and other Pseudomonas, Haemophilus influenzae (including ampicillin-resistant strains), Klebsiella, Enterobacteriaceae, Proteus mirabilis, Escherichia coli, Proteus, Serratia, Citrobacterium, pneumococcus, and Staphylococcus aureus (methicillin-susceptible strains).

3. Generic name: ceftazidime for injection, English name: ceftazidimeforinjection, trade name: Taidexin, manufacturer: South Korea Hanmi Pharmaceutical Co., Ltd.

Tedxin is used for sepsis, lower respiratory tract infection, abdominal and biliary tract infection, complicated urinary tract infection and severe soft tissue infection caused by sensitive gram-negative bacilli. It is particularly useful for immunocompromised infections caused by multiple drug-resistant gram-negative bacilli, nosocomial infections, and central nervous system infections caused by gram-negative bacilli or Pseudomonas aeruginosa.

4. Generic name: cefoperazone sodium sulbactam sodium for injection, English name: cefoperazones odiumandsulbactamsodiumforinjection, trade name:

Shu Pushen, manufacturer: Pfizer ****.

Shupu Shen, the indication is that this product is used alone, and it is suitable for the following infections caused by sensitive bacteria: upper and lower respiratory tract infections; upper and lower urinary tract infections; peritonitis, cholecystitis, cholangitis, and other intra-abdominal infections; Septicemia; Meningitis; and soft tissue infections; bone and joint infections; Pelvic inflammatory disease, endometritis, gonorrhea, and other reproductive infections.

5. Common name: cefminox sodium for injection, English name: cefminoxsodiumforinjection

Cefminol sodium for injection, this product can be used for the following infections caused by sensitive bacteria: respiratory infections: tonsillitis, peritonsillar abscess, bronchitis, bronchiolitis, bronchiectasis (when infected), secondary infections of chronic respiratory diseases, pneumonia, pulmonary purulence.

Urinary tract infections: pyelonephritis, cystitis.

Hello, kill intestinal beneficial bacteria: the third generation of trichosporin is a broad-spectrum, powerful antibacterial drug, which can kill intestinal beneficial bacteria, cause dysbiosis, and cause double infection. 2. Induce antimicrobial resistance of bacteria Sun Sheng:

Adphazard use of third-generation cephalosporins may induce bacterial resistance, reduce or lose efficacy, and increase vulnerability as the disease progresses and worsens. 3. ***: Common adverse reactions of third-generation cephalosporins include rash, fever, allergies, etc.
