This may mean an exhaustive extraction or a more selective extraction aiming to simulate a particular formulation or set of conditions. In extractable studies, the aim is to extract a wide range of substances with different chemical properties, therefore the solvent and extractions conditions should be carefully considered. Therefore, leachables must be profiled in the DP to assess the quality and safety for patients and to trace the sources of leachables present in the DP, extractable studies can support this.ĭue to the wide variety of components used in the manufacturing process, CCS and medical devices and the great number of substances with different chemical properties used in these components, comprehensive screening is required using hyphenated analytical techniques. Leachables in the DP can potentially impact the quality and safety for the patient of the DP. Leachable studies are performed on the DP to identify substances to which the patient is exposed to. In a similar way, substances from the CCS and medical devices which are in contact with the DP can potentially leach to the DP.Įxtractable studies are performed on components used in the manufacturing process, CCS or medical device which are in contact with the DS and DP to identify substances to which a patient might be exposed to. Substances from the manufacturing components can enter the manufacturing process stream and end up in the final DS or DP. However, during the manufacturing process, the DS and DP are in contact with manufacturing components. Ideally, the drug substance (DS) and DP contain only intentionally added ingredients. Regulatory authorities require extractable and leachable (E&L) studies on components used in the manufacturing process, medical devices and container closure systems (CCS) to assess the risk for patient exposure to potential leachables in drug products (DP) 1.

We will discuss an approach for different levels of identification possible and how to increase the level of confidence of identified extractables and leachables. However, how confident are we when we identify a substance using spectral libraries? A match with mass spectral libraries, data from orthogonal techniques, fragmentation data and availability of a reference standard can increase the level of confirmation. Substances need to be accurately identified to enable a toxicological risk assessment that considers the risk of patient exposure. Substances above the set threshold required further investigation if patient exposure exceeds this. In general, an analytical evaluation threshold or reporting threshold is set based on a calculated patient exposure.

Most often LC-MS or GC-MS is used to detect, identify and then quantify extractables and leachables as part of the evaluation of safety and quality.
