Abstract

Abstract A novel HPTLC method has been developed and validated for quantitative determination of omeprazole (OPZ) in capsule dosage form. The method was validated according to the International Conference on Harmonization guidelines for accuracy, precision, linearity, specificity, and robustness. HPTLC aluminum sheets precoated with silica gel 60F254 were used as the stationary phase and chloroformmethanol (9 + 1) as the mobile phase. The mobile phase was found to give compact bands for OPZ (Rf value of 0.39 0.12) in densitometric analysis in the absorbance mode at 302 nm. The linear regression analysis data for the calibration plots showed good linearity (r2 = 0.997) with respect to peak area in the concentration range 503000 ng/band. The mean values of the slope and intercept were 9.896 0.0753 and 1870.761 16.866, respectively. The method was also applied for stability testing of OPZ in different stress conditions and found to be accurate, linear, precise, robust, specific, and stability indicating. The method proposed can be used for QC and stability testing of different dosage forms such as tablets and capsules, as well as for bulk drug analysis of OPZ.
