HPLC Method Development and Validation for Pharmaceutical Analysis

High-Performance Liquid Chromatography (HPLC) is one of the most widely used analytical techniques for the detection, separation, and quantification of drugs. During method optimization, various chromatographic factors are evaluated, such as sample preparation, selection of the mobile phase, choice of column, and type of detector. This article focuses on the processes involved in HPLC method development, optimization, and validation. Due to its benefits, including high speed, specificity, accuracy, precision, and suitability for automation, HPLC is extensively used for the analysis of drugs in multicomponent pharmaceutical dosage forms. The development and validation of HPLC methods play a vital role in new drug discovery, formulation development, manufacturing, and in both human and veterinary studies. Analytical method validation is an essential requirement during drug development and production to confirm that the method is appropriate for its intended application. To comply with Good Manufacturing Practice (GMP) standards, pharmaceutical industries must establish a comprehensive
validation policy that clearly describes validation procedures. This article mainly emphasizes the optimization of HPLC operating conditions.
