ABSTRACT The aim of this study was to validate an analytical method for quantifying solid Diclofenac in a polypharmaceutical capsule using High Performance Liquid Chromatography (HPLC). The mobile phase utilized consisted of a mixture of 20 equal volumes of a 0.1% w/v orthophosphoric acid solution and a 0.16% w/v sodium dihydrogen phosphate dihydrate solution, adjusted to a pH of 2.5, and 80 volumes of methanol. The main peak in the Diclofenac sodium sample preparation was identified, corresponding to the main peak in the standard preparation, confirming specificity for the active ingredient. A linearity analysis was conducted, wherein the Correlation Coefficients (r), Determination Coefficients (r²), and Linearity test all met the required specifications. Additionally, a precision analysis was performed, demonstrating that both repeatability and intermediate precision exhibited a Relative Standard Deviation (RSD) not exceeding 2.0%. Accuracy was also assessed, with a recovery rate of 99.95%, which falls within the specified range of 98-102%. The analytical method was validated in accordance with ICH guidelines and is deemed suitable for the quantification of Diclofenac sodium in polypharmaceutical capsule formulations.
