What are the generation of cephalosporin?

What are the different generations?

• First-generation cephalosporins. First-generation cephalosporins are very effective against Gram-positive bacteria.
• Second-generation cephalosporins.
• Third-generation cephalosporins.
• Fourth-generation cephalosporins.
• Fifth-generation cephalosporins.

What is the difference between first and second generation cephalosporins?

First-generation cephalosporins have coverage against most gram-positive cocci as well as some gram-negative bacteria, e.g., Escherichia coli (E. coli), Proteus mirabilis, and Klebsiella pneumoniae. Second-generation cephalosporins have coverage against Haemophilus influenza (H.

What is the mechanism of action of cephalosporin?

Cephalosporins possess a mechanism of action identical to penicillins: inhibition of bacterial cell wall peptidoglycan synthesis by inhibition of penicillin-sensitive enzymes (transpeptidases, carboxypeptidases) that are responsible for the final three-dimensional structure of the rigid bacterial cell wall.

What do first generation cephalosporins treat?

A broad-spectrum cephalosporin antibiotic used for the treatment of serious bacterial infections in various locations, such as the urinary tract, skin, bone, and lower respiratory tract. A first generation cephalosporin used to treat certain susceptible bacterial infections.

What is 3rd generation cephalosporins?

Third-generation cephalosporins are broad-spectrum antimicrobial agents useful in a variety of clinical situations. No one cephalosporin is appropriate for all infectious disease problems. Cefotaxime and ceftizoxime have the best gram-positive coverage of the third-generation agents.
