Abstract

Abstract Methylprednisolone sodium succinate (MPSS) is a parenteral water-soluble corticosteroid ester. It gives three peaks methylprednisolone (MP), 17-methylprednisolone hemisuccinate (17-MPHS), and methylprednisolone hemisuccinate (MPHS) that share in the assay determination as total MP. It is used on a wide scale in prescribed anti-inflammatory drugs as a common use. The current study aimed to find a rapid RP-HPLC method of MP analysis with high linearity, repeatability, sensitivity, selectivity, and inexpensive to use without the need for any special chemical reagents. The chromatographic system consists of RP-HPLC using the BDS column (250 mm x 4.6 mm x 5 µm). The mobile phase was prepared by mixing the WFI: glacial acetic acid: acetonitrile in a volume ratio (63:2:35) at a flow rate of 2.0 mL/min with detection wavelength at 254 nm at room temperature and injection volume 20 µL. The method manifested a satisfied linearity regression R2 (0.9998–0.99999) with LOD 143.97 ng/mL and 4.49 µg/mL; and LOQ 436.27 ng/mL and 13.61 µg/mL for MP and MPHS respectively. The method proved its efficiency via system suitability achievement in the robustness and ruggedness conduction according to the validation guidelines. High sensitivity according to its LOD and LOQ. So, the current method could be considered in the pharmaceutical industry.
