What is Cefprozil?

Plain description, key identifiers and synonyms

Cefprozil Anhydrous is the anhydrous form of cefprozil, a semisynthetic, broad-spectrum, second-generation cephalosporin with antibacterial activity. Cefprozil binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.
