Supplier Qualification
A comparison of comprehensive third-party excipient GMP audit programs.


Pharmaceutical Technology
Volume 36, Issue 10, pp. 124-127

Conclusion

It is apparent that many generic manufacturers and smaller pharmaceutical companies use means other than physical audit to qualify their suppliers. An ANSI accredited certification program, therefore, is particularly useful because the program has been qualified by ANSI and can be so recognized by government agencies. An ANSI accredited certification program, furthermore, allows pharmaceutical companies to use certification in lieu of site audit for supplier qualification.

Assuring the safety of the drug supply has modified the development of each of these programs. FDA has explicitly stated at meetings and presentations that shared-audit and third-party audit programs are acceptable as part of a supplier qualification program (5). Continuing reports of economically motivated adulteration reminds the industry that each site supplying excipients must be physically audited to ensure conformance to GMP requirements. Supply chain security must begin with a site audit.

Participation by an excipient supplier in any one program can provide adequate assurance of the conformance of the excipient to GMP because the basis of the audit is the well accepted IPEC-PQG GMP Guide for Pharmaceutical Excipients. As described herein, the Rx–360, EXCiPACT, and IPEA programs each exercise great care in the selection, training, and qualification of their auditors. FDA has informally stated that these schemes meet regulatory expectations because they have addressed the issue of auditor competency as a core part of the audit process. Thus the schemes can provide the excipient user with a high degree of assurance that excipient from suppliers that have participated in a program meet cGMP expectations and will continue to do so. The cost barrier for this assurance can be greatly reduced by these programs.

These schemes, therefore, can help to ensure patient safety when the drugs that patients consume have been formulated with excipient components supplied by manufacturers whose facilities have been audited.
