Extractables & Leachables Test

Extractables and leachables are chemicals that migrate from packaging system components, such as containers and closed systems, and may contaminate the drug. In drug development, it is important to assess the potential for the migration of chemicals from containment systems, manufacturing components or delivery devices into the drug product, as these substances are sufficient to cause toxic hazards or affect the stability and efficacy of the drug. Therefore, the regulatory agency requires extractables and leachables (E&L) testing to ensure the quality of the drugs.

Extractables: they are compounds that migrate from the contact surface under more aggressive conditions, such as elevated temperature, extended contact time, or aggressive solvent system.

Leachables: they are compounds that migrate from the contact surface under normal conditions of exposure.
