Artemisinin-based FDC products are recommended by WHO as first-line treatment. However, the current artemisinin FDC products, like β-artemether and lumefantrine, are inherently unstable and require controlled distribution and storage conditions. Moreover, quality control is hampered by lack of suitable analytical methods. Thus, there is a need for a rapid and simple stability-indicating method for the simultaneous assay of β-artemether and lumefantrine. Three reversed-phase fused-core halo HPLC columns (RP-Amide, C18 and Phenyl-hexyl), all thermostated at 30?C, were evaluated. β-artemether and lumefantrine (including stressed), and reference-related impurities were injected and chromatographic parameters were assessed. Optimal chromatographic parameters were obtained using RP-Amide column and isocratic mobile phase composed of acetonitrile and 1 mM phosphate buffer pH 3.0 (52:48; V/V) at flow of 1.0 ml/min and 3 μl injection volume. Quantification was performed at 210 nm and 335 nm for β-artemether and lumefantrine, respectively. Both β-artemether and lumefantrine were separated from each other, and from the specified and unspecified related impurities including degradants. A complete chromatographic run only took four minutes. Evaluation of the method, including Plackett-Burman robustness verification within analytical QbD- principles, and real-life samples showed the method is suitable for quantitative assay purposes of both active pharmaceutical ingredients, with a mean recovery (?RSD) of 99.7% ?0.7%) for β-artemether and 99.7% (?0.6%) for lumefantrine. A rapid, robust, precise and accurate stability-indicating, quantitative fused-core isocratic HPLC method was developed for simultaneous assay of β-artemether and lumefantrine. This method can be applied in the routine regulatory quality control of FDC products.
