Abstract
In this work, an eco-friendly simple, precise reverse phase high-performance liquid chromatography (HPLC) method has been developed and validated for Favipiravir in bulk and tablet dosage form followed by its force degradation study. The proposed method was validated to obtain official requirements including stability, accuracy, precision, linearity, robustness and selectivity as per International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) Guidelines. The estimation was developed on C (18) column reversed-phase using the mobile phase composition as methanol:water (10:90 v/v). The flow rate was set as 1 ml/min, and the maximum absorption was observed at 323 nm using Shimadzu Photo Diode Array detector. The Favipiravir, drug showed a precise and good linearity at the concentration ranges of 10-50 μg/mL. The Revearse Phase High Perforance Liquid Chromatography assay showed the highest purity ranging from 99.90 to 100.02% for Favipiravir, tablet dosage form, and 100.15% was the mean percentage purity. The percent recovery was found within the acceptance limit of (98.6-100.0%). Intra- and inter-day precision studies of the method were less than the maximum allowable limit percentage of relative standard deviation ≤ 2.0. The Favipiravir retention time was found to be 5.00 min. To examine the stability of the drug, various forced degradation studies were conducted on Favipiravir Active Pharmaceutical Ingredient. The developed method was validated according to the ICH guidelines. A very quick, cost-effective, precise and accurate HPLC method for the determination of Favipiravir has been developed and validated in compliance with ICH guidance Q2.
期刊介绍：
The Journal of Chromatographic Science is devoted to the dissemination of information concerning all methods of chromatographic analysis. The standard manuscript is a description of recent original research that covers any or all phases of a specific separation problem, principle, or method. Manuscripts which have a high degree of novelty and fundamental significance to the field of separation science are particularly encouraged. It is expected the authors will clearly state in the Introduction how their method compares in some markedly new and improved way to previous published related methods. Analytical performance characteristics of new methods including sensitivity, tested limits of detection or quantification, accuracy, precision, and specificity should be provided. Manuscripts which describe a straightforward extension of a known analytical method or an application to a previously analyzed and/or uncomplicated sample matrix will not normally be reviewed favorably. Manuscripts in which mass spectrometry is the dominant analytical method and chromatography is of marked secondary importance may be declined.
