Small variations in API purity, impurity profiles, or manufacturing controls can affect the consistency, stability, and performance of the finished sterile drug product. For this reason, McGuff Outsourcing Solutions (MOS) voluntarily applies rigorous additional oversight to the sourcing, qualification, and verification of APIs—extending well beyond baseline requirements for outsourcing facilities.
Quality oversight begins with direct verification of the API manufacturer
MOS personnel, or qualified third-party auditors acting on our behalf, conduct recurring risk-based on-site evaluations of API manufacturers worldwide to assess conformance with U.S. current Good Manufacturing Practices (cGMP).
Analytical verification beyond identity testing
All incoming APIs are quarantined and released only after approval by the MOS Quality Unit. In addition to required identity testing, MOS performs risk-based analytical verification in our in-house microbiology and chemistry laboratories.
Manufacturing discipline, applied at the source
By combining direct cGMP inspection of API manufacturers with expanded analytical verification, MOS applies pharmaceutical manufacturing discipline at the API level—strengthening supply chain integrity and supporting the consistent production of reliable sterile medications.
