TLDR A new accurate and reliable method was developed to measure Spironolactone and Hydrochlorothiazide together in medicines.
A new RP-HPLC method was developed and validated for the simultaneous estimation of Spironolactone and Hydrochlorothiazide in pharmaceutical dosage forms. The method utilized an Inertsil C18 column with a mobile phase of Methanol and Phosphate buffer, achieving retention times of 1.688 mins and 3.282 mins, respectively. The % purity of both compounds was approximately 99.86%, and the method demonstrated high accuracy, precision, and robustness, with a correlation coefficient of 0.999 for both drugs. The method was validated according to ICH guidelines, showing excellent linearity, recovery, and repeatability, making it suitable for routine analysis.
