The FDA conducted an inspection at MedOffice Saglik Endustri Anonim Sirketi’s facility in Turkey from May 6 to 10, 2024, identifying significant violations in Current Good Manufacturing Practice (CGMP) standards for finished pharmaceuticals. Key issues identified included failures in laboratory testing, component verification, and process validation, which affected the compliance of products with the FD&C Act (Federal Food, Drug, and Cosmetic Act).
These violations present product quality and safety risks, potentially impacting consumer health due to unverified product specifications and ineffective process controls.
Key Non-Conformances Identified
Some of the non-conformances identified during the inspection were:
1. Inadequate Testing of Drug Products
MedOffice Saglik Endustri failed to conduct necessary tests to verify the identity and strength of active ingredients in certain over-the-counter (OTC) drug products before their release to the market. By not performing identity and strength tests, the company could not confirm that these products contained the required active ingredient at the appropriate concentration or were free from harmful contaminants.
This testing oversight applied to batches intended for the U.S. market, presenting a risk of non-compliant or potentially unsafe products reaching consumers.
Additionally, the lack of adequate microbiological testing meant there was no guarantee that batches were free from objectionable organisms, further risking contamination and reduced product safety. Without thorough batch testing, MedOffice cannot ensure its products consistently meet the quality specifications necessary for safe use.
2. Insufficient Component Verification
The facility failed to adequately verify the identity of each component used in drug production and did not confirm the reliability of Certificates of Analysis (CoAs) provided by suppliers. In particular, the firm did not conduct identity tests for incoming components, including active pharmaceutical ingredients (APIs), instead relying on CoAs without further validation.
This practice means that the firm did not have evidence-based assurance of the components’ quality, strength, or purity, as required by CGMP. The FDA requires that manufacturers validate the authenticity and reliability of each lot of incoming components to prevent the use of substandard or potentially harmful materials. Without reliable component verification, the firm risks introducing adulterated products into the market due to the possible variability or unsuitability of raw materials.
3. Lacking Process Control and Validation
The facility did not establish validated manufacturing processes or sufficiently qualify equipment, which is crucial to maintaining consistent and safe drug production. Specifically, MedOffice Saglik Endustri did not have adequate procedures to demonstrate that their manufacturing processes would reliably produce drug products that meet their intended specifications for identity, strength, quality, and purity.
RELATED: Qualification vs Validation
Additionally, equipment shared between drug and non-drug products was not properly validated for cleanliness, increasing the risk of cross-contamination. Process validation is essential to ensure the manufacturing process consistently produces products meeting quality standards, with robust process controls in place to monitor production variations. Lacking such controls could result in inconsistencies within batches or between batches, further compromising product integrity and safety.
Recommended CAPA Plan
To address these critical deficiencies, MedOffice Saglik Endustri Anonim Sirketi’s facility must implement a comprehensive CAPA plan. Below are the recommended actions for each non-conformance:
1. Inadequate Testing of Drug Products
Root Cause Analysis
- Testing Non-Conformance: The failure to establish a systematic approach to routine identity and microbiological testing contributed to insufficient quality assurance. This gap meant products were released without fully confirming their quality and safety.
Corrective Actions
- Establish Comprehensive Testing: MedOffice Saglik Endustri is advised to develop and document complete procedures for chemical and microbiological testing, which should be applied to each batch prior to market release. These procedures should cover testing for active ingredient identity, strength, quality, and purity, ensuring the drug products meet all regulatory and quality standards.
Preventive Actions
- Develop and Implement a Risk-Based Testing Framework: Establish a risk-based testing approach to determine the frequency and scope of identity and microbiological tests based on the criticality of each product. This framework will help prioritize high-risk batches, ensuring comprehensive testing coverage aligned with product risk profiles.

- Implement Automated Testing Systems Where Feasible: Use automated testing equipment to reduce human error, enhance repeatability, and increase the accuracy of routine identity and microbiological testing. Ensure these systems are validated and maintained as part of the QMS.
- Strengthen Quality Management System (QMS) Integration: Fully incorporate testing protocols into the Quality Management System, ensuring these procedures are reviewed, updated, and improved regularly. Align routine testing procedures with QMS standards to facilitate a structured approach to maintaining consistent quality.
- Personnel Training and Competency Verification: Conduct regular training sessions on testing methodologies, sampling, and quality standards to reinforce understanding among staff members. Assess competency frequently to ensure testing personnel have up-to-date knowledge and skills necessary for accurate and consistent results.
2. Insufficient Component Verification
Root Cause Analysis
- Testing Non-Conformance: The reliance on supplier-provided COAs without additional verification processes led to quality gaps in the use of unverified raw materials.
SEE MORE: Supplier Qualification in GMP
Corrective Actions
- Implement Reliable Supplier Verification: The firm should perform independent verification of COAs by testing incoming raw materials at predetermined intervals, ensuring they meet quality specifications. Additionally, MedOffice should conduct periodic audits of suppliers to confirm the reliability of their testing data and maintain control over component quality.
Preventive Actions
- Quality System Enhancements: MedOffice should create comprehensive Standard Operating Procedures (SOPs) that will standardize quality control across all manufacturing operations. This includes procedures for equipment qualification, supplier qualification, and verification of incoming materials.
- Periodic Review and Validation: MedOffice is advised to establish a program for regular audits and revalidation to ensure supplier COAs continue to be reliable. This will provide added control over the quality of raw materials and prevent potential contamination or adulteration issues.
- Develop and Maintain Supplier Quality Agreements: Implement quality agreements with all suppliers, clearly outlining specifications, testing standards, and expectations for data accuracy on COAs. Include clauses that require suppliers to notify MedOffice Saglik Endustri of any changes to their testing methods or quality control processes.
- Enhance Documentation and Traceability Systems: Integrate traceability tools to document each batch of raw materials, including COA data, test results, and supplier details. Ensure this documentation is maintained in a centralized system for easy access and audit readiness.
