Container closure selection and compatibility studies
WLI assists its clients in selecting an appropriate container closure system for a drug product. Considerations are given to the intended use of the drug product and the suitability of the container closure system for storage and transportation, including the storage and shipping container for bulk drug product, if appropriate.
Subsequently, testing is conducted to assess compatibility of the drug product with the container. Possible difficulties may be encountered with decomposition of the active pharmaceutical ingredient on contact with components of the container or its closure, contamination with plasticizers or other leachables/extractables, moisture uptake, or inadequate dose recovery. |
