Introduction

Pharmaceutical analysis is central to ensuring drug quality, safety, and efficacy throughout the drug lifecycle. This critical field continually evolves, adopting advanced analytical techniques to characterize drugs, monitor manufacturing, detect impurities, and understand their behavior in biological systems. Meeting stringent regulatory demands and addressing modern drug complexities requires ongoing innovation. Recent literature highlights significant progress across various analytical domains. Modern chromatographic techniques are fundamental. This review explores advancements in High Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), Supercritical Fluid Chromatography (SFC), and Capillary Electrophoresis (CE) for pharmaceutical analysis. These are vital for drug discovery, development, quality control, and impurity profiling, playing a key role in assuring drug safety and efficacy [1].

Significant developments in bioanalytical methods are evident, especially for quantifying drugs in biological matrices. This work also examines recent advances in bioanalytical methods, including chromatography and Mass Spectrometry (MS), for drug quantification. It covers sample preparation, method validation, and applications in pharmacokinetics, drug metabolism, and toxicology within pharmaceutical and forensic contexts [2].

Spectroscopic methods provide indispensable tools. This paper reviews progress in Ultraviolet-Visible (UV-Vis), Infrared (IR), Raman, and Nuclear Magnetic Resonance (NMR) for pharmaceutical analysis. It discusses their utility in identifying, quantifying, and characterizing active pharmaceutical ingredients, excipients, and impurities, emphasizing applications in quality control and counterfeit drug detection [3].

The push for environmental sustainability has integrated green analytical chemistry principles. This article delves into the adoption of these principles in pharmaceutical analysis, exploring strategies to reduce solvent consumption, minimize waste, and employ eco-friendly extraction and separation techniques.
