Overview of Nitrosamine Contamination Concerns in Pharmaceuticals Nitrosamine contamination has emerged as one of the most significant quality control challenges facing the pharmaceutical industry in recent years. These potentially carcinogenic impurities, formed through reactions between secondary or tertiary amines with nitrosating agents, have been detected in various drug products including angiotensin II receptor blockers (ARBs), […]

The Complexity of Natural Product Extracts Natural product extracts represent one of the most challenging matrices in analytical chemistry, containing thousands of compounds spanning an enormous range of polarities, molecular weights, and chemical functionalities. These complex mixtures typically include pigments, lipids, carbohydrates, proteins, and diverse secondary metabolites that can interfere with downstream analysis. The high

Introduction to SPE Cleanup for Pharmaceutical Tablet Analysis Solid-phase extraction (SPE) has become an indispensable technique in pharmaceutical analysis, particularly for LC-MS analysis of tablet formulations. The complexity of tablet matrices—containing active pharmaceutical ingredients (APIs), excipients, fillers, binders, and lubricants—demands robust cleanup procedures to ensure accurate quantification and prevent instrument contamination. According to industry standards,

Therapeutic Drug Monitoring Overview Therapeutic drug monitoring (TDM) represents a critical component of modern clinical pharmacology, enabling healthcare professionals to optimize medication efficacy while minimizing adverse effects. At its core, TDM involves measuring drug concentrations in biological fluids—typically plasma or serum—to ensure they remain within a therapeutic range. This practice has become particularly vital for

Role of SPE in Pharmacokinetics Solid Phase Extraction (SPE) has become an indispensable tool in modern pharmacokinetic studies, particularly in drug metabolism research. As noted in the literature, “Solid-phase extraction is widely used for the preparation of biological samples for further analysis in areas as diverse as clinical chemistry, forensic science, and biomedical and pharmaceutical
