Development and Validation of Spectrophotometric Methods for Simultaneous Estimation of Cefixime Trihydrate and Linezolid in Tablet Dosage Form
Authors
Abstract
A new, simple, rapid and novel spectrophotometric method has been developed for
simultaneous estimation of cefixime trihydrate and linezolid. For this, simultaneous equation
method is used. The method involved measurement of absorbance at two wavelengths, 250 nm
and 286 nm, λ max of linezolid and cefixime trihydrate respectively. This method obeys Beer’s
law in the employed concentration ranges of 2-12 μg/ml for both cefixime trihydrateand
linezolid. The proposed method is recommended for routine analysis since it is rapid, simple,
accurate, specific and also sensitive. This paper describes the development and validation of UV
spectroscopic method for simultaneous estimation of cefixime trihydrate and linezolid in Tablet
dosage form.
