Abstract

Simple, precise, economical, fast and reliable two UV methods have been developed for the simultaneous estimation of Cefixime Trihydrate and Ofloxacin in bulk and pharmaceutical dosage form. Method A is Absorbance maxima method, which is based on measurement of absorption at maximum wavelength of 287 nm and 296 nm for Cefixime Trihydrate and Ofloxacin respectively. Method B is area under curve (AUC), in the wavelength range of 265-301 nm for Cefixime Trihydrate and277-320nm for Ofloxacin. Linearity for detector response was observed in the concentration range of 5-25 μg/ml for Cefixime Trihydrate and 5-25 μg/ml for Ofloxacin. The accuracy of the methods was assessed by recovery studies and was found to be 98.83% and 100.12% for Cefixime Trihydrate and 102.71 % and 99.01 % Ofloxacin by using method A and B respectively. The developed method was validated with respect to linearity, accuracy (recovery), precision and specificity. The results were validated statistically as per ICH Q2 R1guideline and were found to be satisfactory. The proposed methods were successfully applied for the determination of for Cefixime Trihydrate and Ofloxacin in commercial pharmaceutical dosage form.

Abstract

Derivative spectrophotometry offers a useful approach for the analysis of drugs in multi-component formulation. In this study a first order derivative spectrophotometric method is applied for the simultaneous determination of Paracetamol and Domperidone in Tablet dosage form. The measurements were carried out at wavelengths of 262 and 297 nm for Paracetamol and Domperidone respectively. The method was found to be linear (r²=0.999) in the range of 5-25 μg/ml for Paracetamol in the presence of 20μg/ml of Domperidone at 262 nm. The linear correlation (r²=0.999) was obtained in the range of 5-25μg/ml for Domperidone in the presence of 20μg/ml of Paracetamol at 297 nm. The method was successfully used for simultaneous determination of Paracetamol and Domperidone in tablet dosage form without any interference from excipients and prior separation.
