    The document presents a study on the concurrent quantification of Minoxidil (MXL) and Finasteride (FNS) using a Reverse Phase High Performance Liquid Chromatography (RP-HPLC) method. The method was optimized considering factors such as wavelength, the composition of the mobile phase, and pH of buffer. The study concluded that this method is superior to others as it optimizes based on the theoretical aspects of separation and the physicochemical properties of the Active Pharmaceutical Ingredients (APIs) such as pKa and log P. The ratio of Methanol: Milli-Q water and the pH of the mobile phase significantly affected the retention time and resolution of the two APIs.
