Impurities in API Risk Assessment

Impurity risk assessment of Active Pharmaceutical Ingredients (APIs) is the process of determining the potential impact of impurities present in a drug on patient safety and is essential for ensuring drug safety and improving drug quality. Protheragen-ING combines knowledge and skills from various fields such as chemistry, toxicology, analytics, and regulatory affairs to provide specialized impurity risk assessment services to help detect and quantify the presence and level of impurities in APIs. We use appropriate analytical methods for impurity detection, which may include High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), Mass Spectrometry (MS), and others.

Items Introduction Services
Genotoxic Impurity Studies Genotoxic impurities (GTI) are substances that can cause DNA mutations, chromosome breaks, or DNA recombination, can induce gene mutations lead to chromosome breaks and rearrangements at very low concentrations, and are potentially carcinogenic. We can provide genotoxic impurity studies under various relevant regulatory requirements, focusing on providing a series of complete solutions including assessment reports, method development, validation, and sample testing for genotoxic impurities that may be generated in the production process of APIs.
Elemental Impurities Studies Due to the influence of the regional environment (heavy metal pollution), there has always been a high level of concern for elemental impurities in drug declarations. Comprehensive risk assessment of elemental impurities that may be introduced into a drug according to the application of ICH Q3D.
Related Substance Studies APIs may also have other organic impurities during the manufacturing process, from sources such as starting materials, intermediates, by-products, and degradation products, due to their potential impact on the quality, safety, and efficacy of the drug product. Combined with the characteristics of API and production process, we analyze the impurity profiles of API, intermediates, excipients, degradation products, and various related substances generated during the production process, and research and establish reliable detection methods with detection limit, specificity, quantification limit, linearity, etc. by the standard requirements and customer requirements.
Residual Solvent Studies The API production process uses or generates some volatile organic compounds, which are toxic or harmful to the environment and are difficult to remove completely. In addition to this, the final purification of most pharmaceutical ingredients includes a crystallization process that retains small amounts of organic solvents that can become toxic impurities or cause drug degradation. By ICH, USP, ChP, and other relevant regulations and in combination with the API and the characteristics of the production process, we develop and validate methods for residual solvent testing, provide data from the method development process, method validation programs, and reports, and cooperate with the customer in the transfer of the method.
