Chemometric-Assisted UV Spectrophotometric Method for Determination of Cefixime Trihydrate and Cloxacillin Sodium in Pharmaceutical Dosage Form

Abstract

UV spectrophotometry is the simple, precise and accurate method of analysis. Chemometrics are set of statistically improved and verified multicomponent methods for analysis. These methods of analysis were developed using Principle Component Regression (PCR) and Partial Least Square (PLS) to apply and study new technique in project work. The spectra of both drugs were recorded at concentrations within their linear ranges at 2.0–12.0 μg/ml for Cefixime and 5.0–30.0 μg/ml for Cloxacillin. The spectra were recorded in the 220 nm-260 nm wavelength range at wavelength interval of 0.5 nm. International Conference on Harmonization Q2 (R1) (ICH) guidelines were followed to validate the method. The proposed method can be used as alternative analytical tool in quality control of these drugs.
