Abstract

DEVELOPMENT AND VALIDATION OF A NEW UV SPECTROPHOTOMETRIC SIMULTANEOUS EQUATION METHOD FOR ESTIMATION OF CEFIXIME TRIHYDRATE AND ORNIDAZOLE IN A COMBINED TABLET DOSAGE FORM.

Supriya Ulhas Kubal* and Sachi S. Kudchadkar

ABSTRACT

A new UV spectrophotometric simultaneous equation method was developed and validated for the estimation of Cefixime Trihydrate and Ornidazole in pure and pharmaceutical dosage form. Cefixime Trihydrate (Cefix) shows λmax at 288nm and Ornidazole (Orni) shows at λmax 320nm in mixture of methanol and water. The developed method was found to show linearity in concentration (conc.) range of 2-30 μg/ml for Cefixime Trihydrate and Ornidazole with the value of correlation coefficient (R2) 0.998 and 0.999 respectively. The percent Relative Standard Deviation (% RSD) of inter and intra-day precision studies were found to be within limits of NMT 2% concluding that the present method is precise as per ICH guidelines Q2 (R1).[1] The developed method can be used for routine estimation of Cefixime Trihydrate and Ornidazole in bulk and pharmaceutical dosage form.

Keywords: UV spectrophotometry, Cefixime Trihydrate, Ornidazole, Absorbance.
