Cefazedone is a semisynthetic first-generation cephalosporin with activity against Gram-positive and Gram-negative bacteria. Cefazedone 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. Unlike other cephalosporins cefazedone possesses good activity against gram-positive bacteria

Sample Use Guides

In Vivo Use Guide

The doses were: i.v. cefazedone 500 mg and 1000 mg; cefazolin 1000 mg; i.m. cefazedone 500 mg, cefazolin 500 mg.

Route of Administration: Parenteral

In Vitro Use Guide

The sensitivity of 67 strains of Neisseria gonorrhoeae isolated from 1977 to 1978 were tested against cefazedone (Refosporen). All strains including three penicillin-resistant beta-lactamase producing Neisseria were sensitive at a range of 0.0078 to 2.0 ug/ml cefazedone.
