Title: Recent advances in the determination of elemental impurities in pharmaceuticals and drugs – status, challenges and moving frontiers


Biography: V. Balaram


Elemental impurities have been regulated for many decades not only in environmental materials and food products, but also in pharmaceutical and drug products. Metal impurities such as As, Cd, Cu, Pb, Hg, V and Pt in pharmaceuticals and drugs may originate from several sources such as raw materials, catalysts, metal reagents and even manufacturing equipment. An account of the recent changes in the European Pharmacopoeia (EP), the United States Pharmacopoeia (USP) and the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) regulations for inorganic impurities and new strategies to be adopted for heavy metals analyses will be presented. This presentation will also describe the need and scope of metallic impurity profiling and current trends in pharmaceutical research. Rapid screening methods in quality control operations, and a brief account of the classical spectrophotometry and the role of various instrumental methods such as atomic absorption spectrometry (AAS), X-ray fluorescence spectrometry (XRF), instrumental neutron activation analysis (INAA),  inductively coupled plasma atomic emission spectrometry (ICP-AES) and the inductively coupled plasma mass spectrometry (ICP-MS) for the accurate determination of inorganic impurities in pharmaceutical samples will be presented. Further developments in ICP-MS have become very significant in the quality control of bulk drugs and pharmaceutical industry. Recent advances in sample preparation, speciation analysis, quality issues, and application of laser ablation ICP-MS and high-resolution ICP-MS in pharmaceutical analysis and possible future trends will also be discussed.
