Abstract: In the field of pharmaceutical analysis, high-performance liquid chromatography (HPLC) is considered to be the key technique, which is one of the most efficient, quick, and easy methods for the simultaneous determination of two are more drugs. The purpose of the current study is to develop and validate the reversed-phase high-performance liquid chromatographic (RP-HPLC) method for the simultaneous determination of Paracetamol and Fexofenadine HCl. This approach was validated by the standards and The International Conference on Harmonization (ICH), and United States Pharmacopeia (USP) were followed in the development and validation of the method. The chromatographic conditions including a mobile phase comprised of a 35:65 buffer mix and acetonitrile with a 1.0 mL min−1 flow rate were used. A thorough investigation was performed, including linearity and range, specificity, robustness, accuracy, precision, solution stability, and system suitability. The outcomes of the studies have shown that, both Active Pharmaceutical ingredients i.e., Paracetamol and Fexofenadine HCl were separated in about 7.5 min. The variation coefficient for Paracetamol and fexofenadine HCl varied between 0.9992 R2 and 0.9983 R2, respectively. The devised method was proved accurate, as API recoveries in both cases of Paracetamol and Fexofenadine ranged from (99.79%, 100.72%, and 98.64%) to (99.96%, 100.64%, and 99.00%). The method's accuracy was further demonstrated by the solution stability which was 99.84% for Paracetamol, and 100.53% for Fexofenadine HCl. The suggested method for simultaneously measuring Paracetamol and Fexofenadine HCl was established, validated, and there was no evidence of any excipient interaction was observed.
