Improving Quality Through Supplier Audits in Pharmaceuticals
🧾 Improving Quality Through Supplier Audits in Pharmaceuticals
Supplier audits are critical in ensuring that raw materials, APIs, packaging components, and outsourced services meet GMP and regulatory expectations. A strong supplier audit program reduces compliance risks, improves product quality, and builds reliable partnerships.
1. Supplier Qualification & Risk Assessment
-
Perform initial risk assessment of all suppliers (based on material criticality, supplier history, country of origin).
-
Classify suppliers as critical, major, or minor and plan audit frequency accordingly.
-
Include supplier audits as part of the Quality Management System (QMS).
2. Audit Preparation
-
Define audit scope (GMP compliance, quality systems, data integrity, etc.).
-
Prepare a detailed checklist aligned with regulatory guidelines (FDA, EMA, WHO, ICH Q7/Q10).
-
Review supplier’s previous audit history, performance, and complaint records.
3. Audit Execution
-
Inspect quality systems: document control, change control, deviations, CAPA.
-
Evaluate manufacturing practices: equipment, facilities, cleaning, contamination control.
-
Verify raw material handling: sampling, testing, storage, and traceability.
-
Review data integrity practices: ALCOA+ principles, electronic system controls.
-
Assess training programs, qualification of personnel, and compliance culture.
4. Audit Reporting & Communication
-
Issue factual, objective, and evidence-based findings.
-
Classify findings as Critical, Major, or Minor.
-
Share audit report with supplier promptly and request a CAPA plan with timelines.
5. Follow-up & CAPA Verification
-
Ensure suppliers implement effective CAPAs to close audit findings.
-
Conduct follow-up audits for critical suppliers or unresolved findings.
-
Monitor ongoing supplier performance through KPIs (e.g., batch rejections, on-time delivery, complaint rate).
6. Continuous Improvement
-
Use audit results to improve supplier qualification and risk assessment programs.
-
Build long-term relationships with suppliers through training, joint problem-solving, and knowledge sharing.
-
Benchmark supplier performance and reward compliant, high-quality suppliers.
