Development and Validation of UV Spectrophotometric Method for Determination of Cefuroxime in Pharmaceutical Dosage forms

A rapid and sensitive UV-Visible spectroscopic method was developed for the estimation of cefuroxime in pure and its Pharmaceutical formulations. The method was based on the measurement of absorbance of Cefuroxime active moiety of Cefuroxime tablet at 277 nm using methanol as solvent. The absorbance was found to increase linearly with increase in concentration of Cefuroxime which was corroborat...

Kinetic spectrophotometric determination of famotidine in commercial dosage forms.

A simple kinetic spectrophotometric method is described for the determination of famotidine. The method is based on the oxidation of the drug with alkaline potassium permanganate. The reaction is followed spectrometrically by measuring the rate of change of the absorbance at 610 nm. The initial-rate and fixed-time (at 12 min) methods are adopted for determining the drug concentration. The calib...

Kinetic Spectrophotometric Determination of Ramipril in Commercial Dosage Forms

This paper presents a simple and sensitive kinetic spectrophotometric method for the determination of ramipril in commercial dosage forms. The method is based on the reaction of the drug with 1-chloro-2,4-dinitrobenzene (CDNB) in dimethylsulfoxide (DMSO) at 100 ± 1C. The reaction is followed spectrophotometrically by measuring the rate of change of the absorbance at 420 nm. Fixed-time (ΔA) and ...

Spectrophotometric Methods for Determination of Sunitinib in Pharmaceutical Dosage Forms Based on Ion-pair Complex Formation

Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...
