How do you remember which cephalosporin is in which group !!??!
Here is an easy , although imperfect , way to learn many of them .


First-Generation
Almost all cephalosporins have the sound cef in their names , but the first generation cephalosporins are the only ones with a PH. To know the first generation cephalosporins , you must get a PH.D. in PHarmacology .
  • Cephalothin
  • Cephapirin ( Exceptions : cefazolin , cefadroxil )
  • Cephradine
  • Cephalexin

Cefazolin is an important first generation drug that does not have a PH . Do not let this faze you

!

Second-Generation
Second-Generation cephalosporins have fam , fa , fur , fox , or tea in their names . After you get your PH.D. , you would want to gather your family to celebrate ! The FAMily is gathered , some wearing FUR coats and your FOXy cousin is drinking TEA in a toast to your achievement .

  • Cefamandole
  • Cefaclor
  • Cefuroxime ( Exceptions : cefmetazole , cefonicid , cefprozil , loracarbef )
  • Cefoxitin
  • Cefotetan ( pronounced ce-fo-tea-tan )

Third-Generation
TRI for third ( you know triglycerides , etc ) . Most of the third-Generation cephalosporins have a T ( for tri ) in their names .

  • Ceftriaxon
  • Ceftazidime ( Exceptions : cefixime , cefoperazone , cefpodoxin , cefetamet )
  • Cefotaxime
  • Ceftizoxime
  • Ceftibuten

Note that cefotetan ( tea ) is a second-generation drug .

Fourth-Generation

  • There is only one : cefepime And it is the only cephalosporin with a fep in its name . ( Cefpirome is an investigational agent that will also belong in this class . )

First generation will cover Staph
Third Genration will cover Gram negative
Some of the Second Generatoin will cover anaerobes
Fourth generation will cover Staph and Gram negative but it will miss the anaerobes

With each new generation of cephalosporins, the drugs are able to kill an increasing spectrum of gram negative bacteria.

At the same time, the newer cephalosporins are less effective against the gram-positive organisms. The Streptococci and Staphylococci are most susceptible to first-generation cephalosporins.
