Forced degradation studies and stability indicating method were developed for the estimation of Favipiravir by reverse phase High performance liquid chromatography in active Pharmaceutical ingredient and its tablet dosage form. The method was achieved by using C18 column (250 X 4.6mm X 4µm) with mobile phase mixture ortho phosphoric acid and acetonitrile in the ratio 60:40. The mobile phase was allowed to pump with the flow rate 1ml/min by maintaining detection wavelength at 324nm using ultra-violet detector. Favipiravir drug was subjected to various stress conditions according to International Conference of Harmonization Q1A(R2) guidelines to establish stability indicating method. Favipiravir drug was found to be sensitive at peroxide degradation. The impurity peak was characterized by mass spectral studies. The method was validated for analytical standards such as linearity, accuracy, Precision, sensitivity and robustness. A rapid and sensitive method was developed for the estimation of favipiravir which indicates its stability indicating behavior.

Force degradation studies of drug substance give perceptive knowledge about the intrinsic stability of the molecule as well as possible degradants which formed during the shelf life of drug and thus, aid within the successive development of its stable formulation. A number of analytical methods with hyphenated techniques are required for the identification, determination and characterization of degraded product and impurities produce during different conditions of stress studies; Chromatographic methodology play a vital role in the field of impurity and degradation profiling .This review summarizes the current regulatory requirements guidelines for the laboratory performance of forced degradation and its application for the development of stability indicating method. There are number of strategies have been implemented for the quantitative assessment of antiviral drugs. This study will provide detailed literature on stability- indicating HPLC/ RP-HPLC approaches for the development and validation of various antiviral drugs.

Abstract Background A sensitive, precise, and stability-indicating high-performance thin-layer chromatographic (HPTLC) method has been developed for the analysis of Remogliflozin etabonate in tablet formulation. HPTLC plates precoated with silica gel 60 F254 were used as the stationary phase; methanol: ethyl acetate: toluene: NH3 (2:4:4:0.1, v/v/v) was used as mobile phase, and densitometry was used for the quantitative estimation of the drug. The proposed method was validated with respect to linearity, accuracy, precision, and robustness and applied for the estimation of drug in tablet dosage form. Results The Rf value of Remogliflozin etabonate was observed to be 0.61. The densitometric estimation was performed in reflectance mode at 229 nm. The method was found to be linear in the range of 500–8000 ng/band for Remogliflozin etabonate. The possible degradation pathway was estimated by performing forced degradation studies. The degradant peaks were well resolved from the drug peak with acceptable resolution in their Rf value. Conclusion An accurate and precise high-performance thin-layer chromatographic method has been developed for the quantification of Remogliflozin etabonate in tablets. Forced degradation studies were performed, and drug was found to be highly susceptible to acid, base hydrolysis, and oxidative stress degradation and gets converted into active drug Remogliflozin. Both Remogliflozin etabonate and Remogliflozin bands were well resolved. The method was applied for the analysis of drug in tablet formulation, and it can be used for routine quality control analysis, as well as for the analysis of stability samples.
