Excipient Testing

Pharmaceutical excipients are substances other than the active pharmaceutical ingredient (API) that have been appropriately evaluated for safety and are intentionally included in a drug delivery system. For example, excipients can do the following: aid in the processing of the drug delivery system during its manufacture; protect, support, or enhance stability, bioavailability, or patient acceptability; assist in product identification; and enhance any other attribute of the overall safety, effectiveness, or deliver of the drug during storage or use.

Nelson Laboratories performs full monograph testing for excipients routinely.
