Genotoxic Contaminant Analysis and Control in Drug Substances
p. The rising scrutiny of drug product safety has propelled genotoxic impurity assessment to the forefront of API production. These substances, even at exceedingly minute concentrations, possess the potential to induce genetic injury, thus necessitating robust management strategies. Modern analytical methodologies, such as LC-MS and GC-MS, are vital for the discovery and measurement of GTIs, requiring high-sensitivity methods and rigorous verification protocols. Additionally, the implementation of risk-based techniques, including threshold of toxicological concern, plays a critical role in establishing appropriate acceptance criteria and guaranteeing patient safety. In conclusion, proactive genotoxic impurity regulation is paramount for preserving the purity and protection of pharmaceutical products.
Quantification of Stable Isotope-Labeled Drug Breakdown products
A rigorous determination of drug metabolism often hinges on the accurate measurement of steady-state isotope-tagged drug breakdown products. This approach, utilizing radioactive isotope-tagging, allows for separate identification and accurate determination of metabolic products, even in the presence of the parent drug. Techniques frequently employed include liquid analysis coupled with tandem mass detection (LC-MS) and gas analysis – mass analysis (GC-MS). Detailed consideration of matrix effects and correct recovery procedures are essential for achieving robust and relevant information. Additionally, reliable standard adjustment is essential to ensure quantitative precision and comparability across different experiments.
