The first article in this series discussed the cephalosporin antibiotic agents as a class, including the similarities in their structure, antimicrobial action, and toxicity. Part II focuses on the difference between commercially available first- and second-“generation” agents.
The cephalosporins are classified using various criteria, including vulnerability to beta-lactamase hydrolysis and antibacterial activity. The latter classification is based on the in vitro activity of the individual agents, with each succeeding “generation” possessing a greater spectrum of activity than the previous generation(s).
