[Derivative spectrophotometric and NMR spectroscopic study in pharmaceutical science].

This review starts with an introduction of derivative spectrophotometry followed by a description on the construction of a personal computer-assisted derivative spectrophotometric (DS) system. An acquisition system for inputting digitalized absorption spectra into personal computers and a BASIC program for calculating derivative spectra were developed. Then, applications of the system to drug a...

Derivative Spectrophotometric Method for Determination of Losartan in Pharmaceutical Formulations

Losartan, a highly effective blood pressure lowering agent, has been widely used for the treatment of hypertension. A fast and reliable method for the determination of losartan was highly desirable to support formulation screening and quality control. A first derivative UV spectroscopic method was developed for determination of losartan in the tablet dosage form. The first derivative spectrum r...

Direct and Derivative Spectrophotometric Determination of Gemifloxacin Mesylate in Pure Form and Pharmaceutical Preparations

Two simple, quick and sensitive methods were described for the spectrophotometric determination of Gemifloxacin mesylate (GFX) either in pure form or in the Pharmaceutical form. The methods were based on the reaction of GFX as ‘n’ electron donor with Chloranilic acid(CLA) and Parachloranil(CL) as π acceptors to give highly coloured complex species. The coloured products were quantitated spectro...

Determination of Metoprolol in Pharmaceutical Preparations by Zero-, First-, Second- and Third-order Derivative Spectrophotometric Method

In this study, zero-, first-, secondand third-order derivative spectrophotometry methods were developed for the determination of metoprolol in pharmaceutical preparations. In zero order spectrophotometry, absorbance values were measured at 276 nm in zero order spectra of solution of metoprolol in methanol in the range of 240-310 nm. In first derivative spectrophotometry, absorbance values were ...
