Quality Control at Adragos Leipzig: From Manufacturing to Analysis

When choosing a partner to support your pharmaceutical manufacturing, quality control is a crucial factor that can define the safety, effectiveness, and marketability of your product. This makes quality control important for ensuring safety, compliance, and operational efficiency throughout the manufacturing process. At Adragos Leipzig, part of the global CDMO network of Adragos Pharma, we understand that pharmaceutical companies, whether established industry giants or innovative startups, need more than a supplier; they need an expert ally. Our approach integrates quality control into all operational processes to maintain product standards and support continuous improvement. This article will compare the industry’s quality control process options and demonstrate how Adragos Leipzig delivers exceptional value from manufacturing to analysis. By integrating quality control throughout every stage of the business process, we ensure compliance and enhance overall operational efficiency.

Things to Know: Why Quality Control Matters

Quality control is not just a regulatory tick box. For pharmaceutical companies, it means:

• Consistent product safety and efficacy
• Compliance with international regulations, standards, and quality requirements
• Faster time-to-market and minimized batch failures by addressing production problem early
• Confidence in every step, from raw material to finished product, with a focus on the customer’s needs
• Quality control ensures only safe and compliant products reach the market

Quality control ensures the service meets established standards and customer expectations and it helps companies respond to consumer demands by ensuring products meet market expectations.

Testing products at various stages of manufacturing is essential to detect issues early and maintain quality before products reach the market.

Manual quality control processes can be time consuming, requiring significant effort for data collection and quality testing, while our quality control processes are designed to meet customers’ needs and ensure customer satisfaction.

At Leipzig’s facility, we employ advanced analytical methods, robust documentation, and a holistic system under the strict oversight of the German Medicines Act (Arzneimittelgesetz, AMG). 

Raw Materials: The First Step in Quality Control

The journey to high-quality products begins long before manufacturing: it starts with the careful selection and inspection of raw materials. At Leipzig, we use a range of quality control methods to ensure all raw materials meet stringent standards. Through detailed inspection, statistical quality control, and continuous monitoring, our team verifies that each batch aligns with the level of quality required for the final product. This proactive approach helps prevent defects and maintain high standards, ensuring customer satisfaction.

In industries such as food and pharmaceuticals, rigorous testing and supplier verification are standard to guarantee safety and compliance. Quality control professionals use data collection, control charts, and statistical methods to monitor for any variances that could impact the process. By addressing potential issues early, we eliminate risks, improve performance, and reduce the chance of defective products advancing.

This helps maintain high standards while also reducing production costs and improving results.

Ultimately, the quality of raw materials sets the tone for the entire production process. By investing in robust quality control at this initial stage, Adragos Leipzig ensures that every product meets customer expectations and regulatory requirements. Our commitment to thorough inspection, statistical analysis, and ongoing monitoring allows us to deliver high-quality products and highlights why quality control is crucial for business success.

Examples: Our Quality Control in Action

Our comprehensive quality control process covers every critical stage, with quality control performed at various stages of the manufacturing process and production processes closely monitored to ensure consistency and compliance. Several methods quality control employs are used to ensure product quality, including testing products and evaluating product attributes.

Routine Analytics and Statistical Quality Control

• Raw material analysis: Checking both active ingredients and excipients.
• Bulk goods and product analysis: Sampled products are selected and tested to ensure compliance with specifications, with testing products at various stages to detect any deviations early.
• Batch release testing: Testing semi-solids and non-sterile liquids includes evaluating the key product attributes to confirm they meet required standards before release.
• Stability testing: Long-term evaluation of product strength and purity.
• Residual solvent analysis: Ensuring purity and compliance.

Microbiology

• Non-sterile API and product testing
• Total aerobic microbial count (TAMC) and total yeast and mold count (TYMC)

Method Development and Validation

• Custom-developed analytical methods (HPLC, GC, GC-headspace, UV-VIS, titration)
• Dissolution model design
• Development of cleaning validation methods 
• Planning and execution of method transfers 

Department Function: The Purpose of the Quality Control Department

Our quality control department exists to ensure that each product batch meets its pre-defined standards and regulatory requirements. A primary focus of the department is the inspection aspect of quality control, which involves detecting, recording, and categorizing defects using specialized tools and techniques. Our routine work includes:

• Monitoring and testing at each step
• Efficient problem detection and resolution
• Strong documentation via a validated paper-based documentation system
• Smart use of software like ERP-GUS, Perfact, and Seritrack

Presenting results clearly is essential for supporting decision-making and ensuring compliance with safety and quality standards.

All of this is overseen by our experts, which also manages risk-based qualification, supplier evaluation, and regular audits, including self-inspections, PQRs (Product Quality Reviews), and inspections by government inspectors as part of regulatory oversight.

Metrics: How We Measure Quality Control

Adragos Leipzig uses clearly defined quality control metrics to track, document, and improve each process, such as:

• Batch rejection rates
• Turnaround time for batch release
• Microbial load counts
• Method validation success rates
• Stability failure rates

During data collection, sampled products are analyzed to track these quality metrics and ensure compliance with standards. A quality control chart is used to visually monitor key metrics and detect deviations from expected performance, allowing for timely corrective actions.

By closely following these metrics, we quickly identify and correct deviations, providing a solid foundation for continuous improvement.

Components: The Building Blocks of a Reliable Quality Control System

Here is what sets our quality control system apart:

• Risk-based cross-contamination management: Proactive approach to prevent mix-ups and contamination at every stage.
• Regular audits and self-inspections to ensure compliance.
• Continuous monitoring and optimization of production processes to maintain consistent product quality and identify potential bottlenecks.
• Validated, secure, and transparent documentation and software systems.
• Comprehensive training and development for QC staff.
• Integration with our quality assurance (QA) processes for end-to-end coverage.

With Adragos Leipzig, you are gaining a partner whose entire infrastructure is built for reliability, traceability, and regulatory readiness.
