How Do Third-generation Cephalosporins Work?

Cephalosporins are broad-spectrum antibiotics used to manage a wide range of bacterial infections. They are derived from the mold Acremonium (previously called Cephalosporium). Cephalosporins are grouped into five generations based on their spectrum of coverage against gram-positive and gram-negative bacteria. They are administered intravenously, intramuscularly, or orally depending on the infection.

Third-generation cephalosporins are more effective against gram-negative bacteria than the first and second generations. They are usually effective against bacteria that may be resistant to previous generations of cephalosporins.

Cephalosporins inhibit bacterial cell wall synthesis. The bacterial cell wall is strengthened by the cross-linking of peptidoglycans with the help of penicillin-binding proteins. Cephalosporins have beta-lactam rings that bind with penicillin-binding proteins and block them. The cross-linking of peptidoglycans is then hampered, and the cell wall is not formed, resulting in the death of the bacterial cell.
