Development and Validation of a HPTLC Method for the Estimation of Cefpodoxime Proxetil.

A simple, precise, accurate and rapid high performance thin layer chromatographic method has been developed and validated for the determination of cefpodoxime proxetil in dosage form. The stationary phase used was precoated silica gel 60F²⁵⁴. The mobile phase used was a mixture of chloroform: methanol: toluene (4:2:4 v/v/v). The detection of spot was carried out at 289.0 nm. The method was validated in terms of linearity, accuracy, precision and specificity. The calibration curve was found to be linear between 100 to 700 ng/spot for cefpodoxime proxetil. The limit of detection and the limit of quantification for the cefpodoxime proxetil were found to be 30 ng/spot and 90 ng/spot, respectively. The proposed method can be successfully used to determine the drug content in marketed formulation. [ABSTRACT FROM AUTHOR]
