P. Favetta et al., Simultaneous quantification of ceftazidime and pyridine, its main degradation product, by highperformance liquid chromatography, ANAL LETTER, 33(12), 2000, pp. 2465-2475
A high performance liquid chromatographic method for the simultaneous assay
of ceftazidime and pyridine, the principal degradation product of ceftazid
ime, is described. The method was fully validated in terms of recovery, lin
earity, selectivity and precision. An application was done on stability of
ceftazidime at 40 mg.mL(-1) in infusion solutions 0.9% NaCl and 5% glucose
on 24 hours in ambulatory infusion device. Quantification results of pyridi
ne were more linear and accurate than ceftazidime. Pyridine was a good labe
l in ceftazidime stability studies.
