Abstract

Five simple and sensitive visible spectrophotometeric methods have been developed for the quantitative estimation of Tipranavir in bulk drug and pharmaceutical preparations including the un-interruption of the excipients and impurities. All these method have different linearity ranges. All these method are simple, Accurate, precise and very effective even at low concentrations and used for the quantitive estimation of Tipranavir in commercial formulations.
