Novel Spectrophotometric Method Development for the Estimation of Boceprevir in Bulk and in Pharmaceutical Formulations

Abstract

A New, Simple, Rapid and economical extractive spectrophotometric methods were developed for the determination of Boceprevir (anti-retroviral drug). Boceprevir is a direct acting protease inhibitor for the treatment of hepatitis C. It also has two isomers in which the S isomer is more active than the R-isomer. The methods were based on the formation of color chromogens with Bromo cresol green, Bromo thymol blue, Bromo phenol blue and Methyl orange indicator. The extractive spectrophotometry was carried out with phthalate buffer and chloroform. The absorbances of the chromogens were measured at 410 nm and 415 nm against the corresponding reagent blank. The proposed methods have been successfully applied to the bulk drug. The method has been statistically evaluated and was found to be precise and accurate.
