M. Kamberi et al., DETERMINATION OF CIPROFLOXACIN IN PLASMA AND URINE BY HPLC WITH ULTRAVIOLET DETECTION, Clinical chemistry, 44(6), 1998, pp. 1251-1255
A simple, sensitive isocratic method for the detection and quantificat
ion of ciprofloxacin in plasma and urine has been developed. The assay
consisted of reversed-phase HPLC with ultraviolet detection. Plasma p
roteins were removed by a fast and efficient procedure. For the urine
samples, the only required sample preparation was dilution. Separation
was achieved on a C-18 reversed-phase column. The quantification limi
t was 0.01 mg/L in plasma and 0.5 mg/L in urine. This method was suffi
ciently sensitive for pharmacokinetic studies.
