Comparative Analysis of Cephalosporins: Pharmacokinetics and Pharmacodynamics
Year: 2025
Type: article
Abstract: Cephalosporins are among the most commonly used and versatile groups of β-lactam antibiotics with broad-spectrum antimicrobial activity. Their PK and PD characteristics differ greatly between generations, which affects their clinical use and efficacy against bacterial infections. This review offers an extensive comparative study of the pharmacokinetic characteristics — such as absorption, distribution, metabolism, and excretion — and the pharmacodynamic concepts underlying the therapeutic activity of different cephalosporins. Special attention is given to how structural changes through generations affect half-life, tissue penetration, antibacterial spectrum, and resistance patterns. The review also mentions the interaction among PK/PD indices, such as time above minimum inhibitory concentration (T>MIC), and clinical endpoints. These variables are important in order to ensure optimized dosing regimens for therapeutic success with a reduced possibility of resistance. This review makes it evident that specific antibiotic therapeutic approaches based on unique PK/PD profiles would be required for improved patient treatment and fighting off the emerging epidemic of antimicrobial resistance.
