Development and Validation of Simultaneous Spectrophotometric Methods for Drotaverine Hydrochloride and Aceclofenac from Tablet Dosage Form
Two simple spectrophotometric methods have been developed for simultaneous estimation of drotaverine hydrochloride and aceclofenac from tablet dosage form. Method I is a simultaneous equation method (Vierodt's method), wavelengths selected are 306.5 and 276 nm. Method II is the absorbance ratio method (Q-Analysis), which employs 298.5 nm as λ(1) and 276 nm as λ(2) (λmax of AF) for formation of ...
متن کاملDevelopment and Validation of Spectrophotometric Methods for Simultaneous Estimation of Escitalopram oxalate and Etizolam in their Combined Tablet Dosage Form
Three simple, rapid, accurate, precise and cost-effective UV spectrophotometric methods have been developed and validated for simultaneous estimation of Escitalopram oxalate and Etizolam in tablet dosage form. The UV methods have been developed utilizing concept of standard addition utilizing 0.1 N HCl as a solvent. Method I is estimation using simultaneous equation method at 238.2 nm (λmax of ...
متن کاملDevelopment and Validation of Spectrophotometric Method for Simultaneous Estimation of Sitagliptin Phosphate and Simvastatin in Tablet Dosage Form
A simple and accurate method of analysis to determine Sitagliptin Phosphate (STG) and Simvastatin(SMV) in combined dosage forms was developed using simultaneous equation method at 267.0nm for Simvastatin and 238.0 nm for Simvastatin in spectra of their solutions in methanol: water(90:10). The calibration curves were linear [correlation coefficient (r) = 0.986 for STG and 0.998 for SMV] in conce...
متن کاملDevelopment and Validation of Spectrophotometric Methods for the Estimation of Mesalamine in Tablet Dosage Forms
Three simple and sensitive visible spectrophotometric methods (A, B, and C) have been developed for the quantitative estimation of mesalamine in bulk drug and pharmaceutical dosage forms. Methods were based on the formation of colored chromogens, which were measured at 552 nm, 440 nm, and 494 nm, respectively. The results obtained with the proposed methods were found to be unsatisfactory with t...
متن کاملDevelopment and validation of spectrophotometric methods for the estimation of mefloquine hydrochloride in bulk and tablet dosage form
Two new simple, selective, sensitive and economical methods (A and B) have been developed for the analysis of mefloquine hydrochloride in pure and pharmaceutical dosage form. The methods were based on ion-pair complexation between drug and dyes like metanil yellow and bromophenol blue at an optimum pH 2.8. The colored chromogens were measured at 410 nm (λmax) for method A and 415 nm (λmax) for ...
