It is better to use cephalosporin for several generations, and the first few generations of cephalos

The fourth is good, *** small, the effect is good, but it is used less, if it is commonly used, it is easy to produce drug resistance, there is no fifth generation at present, so the third generation is generally used.

It has to be four. There are exam questions.

There are 20 species of third-generation cephalosporin classification.

They are: cefotaxime sodium, cefoperazone, ceftazidime, ceftriaxone, cefazoloxime, cefmethoxime, cefpimide, ceftitan, cefixime, cefpoxime, ceftamec, cefdizime, cefotaxane, cefdinir, ceftrane, laoxycephalosporin, cefbrune, cefminol, cefrozine.

Cefixime, ceftriaxone, ceftazidime, cefoperazone, cefdizime.

Third generation:

Cefotaxime sodium, cefoperazone, ceftazidime, ceftriaxone, cefazoloxime, cefmeme, cefepimide, cefepime, cefepime, ceftametaxim, cefdizine, cefotaxane, cefdinir, ceftrane, laoxycephalomene, cefbutene, cefmino, cefrozil.

The third generation of cephalosporin mainly has the following types:

Cefotaxime (Kaifuron), ceftriaxone (Bacterium), Ceftazidime (Fudaxin), cefdizime (Modia), cefoperazone.

Pioneer), cefmexime (Anjiejian), cefazoloxime, cefixime (Shisu), cefbrune, cefdinir, ceftoran, etc.

Cephalosporins are a class of antibiotics obtained by semi-synthetically modifying the side chain of natural cephalosporin C obtained from the culture of Cephalosporinus corona.

There are about 30 commonly used types, which are divided according to the order of their invention and antibacterial properties.

First, second, third, fourth generation. Do not use before or after drinking. It is very easy to go into shock, syncope, and even life-threatening in the elderly.

In the antibiotic market, cephalosporin antibiotics occupy a large share, and their related intermediates also show considerable market potential. The most sold varieties of cephalosporin antibiotics are ceftriaxone sodium, cefazolin sodium, cefotaxime, ceftriazine, cefoperazone and cefuroxime (ester).

Oral use: cefixime, ceftorenate, cefdinir, cefbutene, cefpaximelate, ceftametaxim.

For injection: cefotaxime, cefazoloxime sodium, cefmethoxime, ceftriaxone, ceftazidime, cefdime sodium, cefpiramide sodium, cefoperazone.

Suggestions:

There are mainly the following types: cefotaxime (Kaifuron), ceftriaxone (fungus), ceftazidime (Fudaxin), cefdizime (Modi), cefoperazone (Xianfengbi), cefmetroxime (Anjiejian), cefazoloxime, cefixime (Shifusu), cefbrune, cefdinir, ceftoran, etc.
