For example, the fourth generation of cephalosporins is not recognized as such in Japan. [citation needed] In Japan, cefaclor is classed as a first-generation cephalosporin, though in the United States it is a second-generation one; and cefbuperazone, cefminox, and cefotetan are classed as second-generation cephalosporins.
The basic structure of first generation cephalosporins. First generation cephalosporins were the first cephalosporins on the market. They have good antimicrobial activity against gram-positive bacteria but limited activity against gram-negative species. [25] The chemical structures of the first generation cephalosporins are fairly simple.
Cefalotin / ˌ s ɛ f ə ˈ l oʊ t ɪ n / or cephalothin / ˌ s ɛ f ə ˈ l oʊ θ ɪ n / is a first-generation cephalosporin antibiotic with broad spectrum antibiotic activity. [1] [2] It was the first cephalosporin marketed (1964) and continues to be widely used. [3]
Cefazolin, also known as cefazoline and cephazolin, is a first-generation cephalosporin antibiotic used for the treatment of a number of bacterial infections. [2] Specifically it is used to treat cellulitis, urinary tract infections, pneumonia, endocarditis, joint infection, and biliary tract infections. [2]
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
The β-lactam core structures. (A) A penam.(B) A carbapenam.(C) An oxapenam.(D) A penem.(E) A carbapenem.(F) A monobactam.(G) A cephem.(H) A carbacephem.(I) An oxacephem. This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class.
Cephalosporins (First generation) Cefadroxil: Duricef: Good coverage against Gram-positive infections. Gastrointestinal upset and diarrhea; Nausea (if alcohol taken concurrently) Allergic reactions; Same mode of action as other beta-lactam antibiotics: disrupt the synthesis of the peptidoglycan layer of bacterial cell walls. Cefazolin: Ancef ...
Cefalexin is a β-lactam antibiotic within the class of first-generation cephalosporins. [4] It works similarly to other agents within this class, including intravenous cefazolin, but can be taken by mouth. [5] Cefalexin can treat certain bacterial infections, including those of the middle ear, bone and joint, skin, and urinary tract. [4]
