Toxicological Risk Assessment (TRA) – An Overview

Impurities in medicinal drug substances (API) or medicinal drug products, including Extractables and Leachables (E&L), not only affect the product quality but also pose a significant risk to the patient population. Toxicological Risk Assessment (TRA) of impurities, especially potential genotoxic impurities, is essential to control and/or limit its usage at unsafe levels.

Toxicological Risk Assessments of impurities and E&L are structured scientific processes involving hazard identification and risk assessment. For such risk assessment, ICH M7 recommended and validated tools are used in pharmaceuticals under the purview of Toxicological Risk assessment services.

Freyr’s toxicologist team under Toxicological Risk Assessments services has supported numerous global clients and addressed the issues associated with Toxicological safety Assessment and impurities in drug substances, drug products, residual solvents, process impurities and elemental impurities.
