How Do First-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 or orally depending on the infection.

First-generation cephalosporins act on all gram-positive bacteria such as staphylococci and streptococci and show little activity against gram-negative bacteria.

First-generation cephalosporins inhibit bacterial cell wall synthesis and have the same mode of action as other beta-lactam antibiotics (such as penicillins). They disrupt the synthesis of the peptidoglycan layer forming the bacterial cell wall. The peptidoglycan layer is important for cell wall structural integrity.
