Polarographic analysis of cephalexin

Electrochemical analysis of cephalosporin antibiotics

A review is presented on electroanalysis studies and methods for the determination of cephalosporin antibiotics in either simple solutions or biological fluids. Some general data about the electroactivity of cephalosporins are given and the analytical utilization of those data together with the corresponding analytical parameters, compiled from different literature sources.

Penicillins and cephalosporins. Physicochemical properties and analysis in pharmaceutical and biological matrices

Penicillins and cephalosporins belong to the most prescribed antibiotics. Despite the relatively extended knowledge of these drugs, the qualitative and quantitative analysis of the compounds still gives rise to many problems. These difficulties are due to the chemical instability of the common beta-lactam nucleus, the minor differences in chemical structures between the analogues, and the complex and relatively fast degradation of the compounds in aqueous solutions. In this review a compilation of the physicochemical properties, the degradation routes and methods for analysis of these substances in biological and other matrices is presented.
