A review of analytical methods for the estimation of favipiravir in pharmaceutical dosage forms

This review article aimed to provide detailed information on developed analytical methods for the estimation of favipiravir in pharmaceutical dosage forms. This review article was prepared by gathering various analytical methods available in the literature for the determination of favipiravir. The various analytical methods available included spectroscopic methods such as UV spectroscopic methods, visible spectrophotometric methods, Fourier transform infrared spectroscopic (FTIR) method, spectrofluorimetric method, chromatographic methods such as reverse-phase high-performance liquid chromatographic (RP-HPLC) methods, thin layer chromatography (TLC) and hyphenated techniques such as ultra-performance liquid chromatography-tandem mass spectrometric (UPLC-MS/MS) methods, liquid chromatography-tandem mass spectrometric (LC-MS/MS) methods and electrical methods such as voltammetric methods. This article contains the information necessary to carry out the research work for the estimation of favipiravir in pharmaceutical dosage forms using analytical techniques. The present review article can be effectively investigated to conduct future analytical research for the estimation of favipiravir.
