Arten der Validierung in der pharmazeutischen Industrie: ein Leitfaden

Validation in the pharmaceutical industry is a critical procedure that ensures the safety, quality, and efficacy of drugs. Required by regulatory bodies such as the FDA, EMA, and WHO, validation is a cornerstone of pharmaceutical manufacturing, offering documented evidence that processes operate as intended. This article will define pharmaceutical process validation and its practical applications in the pharmaceutical industry.

How to define pharmaceutical process validation?

Validation in the pharmaceutical industry is the process of generating documented evidence that a specific procedure, process, or activity consistently leads to the expected results. It is essential for ensuring product safety and compliance with guidelines such as ICH guidelines for process validation and WHO guidelines for validation.

Pharmaceutical process validation is not just about meeting legal requirements; it is a proactive quality assurance measure that prevents issues like cross-contamination and product failure, thereby protecting public health and maintaining trust in pharmaceutical products. There are different types of pharmaceutical process validations, which we will elaborate further on.

Arten der Validierung in der Pharmazie

1. Prozess-Validierung

This type confirms that the manufacturing process produces outputs that meet predefined specifications. It is conducted in three stages: process design, process qualification and continued process verification. This is a fundamental requirement outlined in FDA’s Current Good Manufacturing Practices (cGMP).

2. Validierung der Reinigung

Dadurch wird sichergestellt, dass die Reinigungsverfahren Rückstände, Verunreinigungen oder Mikroorganismen wirksam von den Geräten entfernen, um eine Kreuzkontamination zu verhindern. Die Reinigungsvalidierung ist besonders wichtig für Mehrproduktanlagen.

3. Validierung der Analysemethode

Überprüft die Genauigkeit, Spezifität, Reproduzierbarkeit und Robustheit von Methoden, die zur Prüfung pharmazeutischer Produkte verwendet werden. Für diesen Prozess ist die Einhaltung von ICH Q2(R2) erforderlich.

4. Validierung der Ausrüstung

Bestätigt, dass die Ausrüstung konsistent innerhalb der erforderlichen Parameter funktioniert und die Produktion von Qualitätsprodukten unterstützt. Dazu gehören Qualifizierungsstufen wie Designqualifizierung (DQ), Installationsqualifizierung (IQ), Betriebsqualifizierung (OQ) und Leistungsqualifizierung (PQ).

Häufig werden die Begriffe Qualifizierung und Validierung gemeinsam verwendet. In der pharmazeutischen Produktion dienen sie jedoch unterschiedlichen Zwecken.

- Bei der Qualifizierung geht es darum sicherzustellen, dass Geräte, Systeme oder Einrichtungen wie erwartet funktionieren. Dazu gehören Aktivitäten wie Designqualifizierung (DQ), Installationsqualifizierung (IQ), Betriebsqualifizierung (OQ) und Leistungsqualifizierung (PQ).

- Validation in pharma, on the other hand, has a broader scope. It ensures that the entire process, including equipment, systems, and methods, consistently produces a product meeting predefined quality standards.

Diese Unterscheidung ist von entscheidender Bedeutung für das Verständnis der Schritte, die zur Gewährleistung der Produktqualität und zur Einhaltung der gesetzlichen Vorschriften erforderlich sind.

Die Schritte der Prozessvalidierung

Die Validierung in der pharmazeutischen Industrie erfolgt in der Regel nach einem systematischen Ansatz:

• ‍Design qualification (DQ): this initial step ensures that the proposed design of the equipment or process meets the requirements for the intended purpose.

• Installation qualification (IQ): in this phase, it is confirmed that the equipment or systems are installed correctly and according to the manufacturer's recommendations.

• Operational qualification (OQ): here, it is determined whether the systems and equipment operate according to the intended operating ranges.

• Performance qualification (PQ): the final step involves testing that the equipment consistently performs according to the process parameters and can produce the desired output.

Die Bedeutung eines systematischen Ansatzes

A systematic approach to validation is crucial because it helps identify potential variability in processes and establishes measures to control these variables. This is not just about ticking off a compliance checklist; it's about guaranteeing the quality and consistency of life-saving drugs in qualitative healthcare packaging. This includes ensuring secure and tamper-evident solutions such as blister packs for medication, which protect dosage integrity and enhance patient safety.

Validierung und ihre Rolle in der Qualitätssicherung

Validation is an integral part of Quality Assurance (QA) in the pharmaceutical industry. It is a proactive measure that identifies potential problems before they affect the final product. It is a preventive approach rather than a reactive one, saving companies from costly recalls and maintaining their reputation.

Das rechtliche Umfeld

Das Erfordernis der Validierung stützt sich auf Vorschriften wie die Current Good Manufacturing Practices der FDA (entdecken Sie, warum GMP wichtig ist), die Richtlinien der Europäischen Arzneimittelagentur (EMA) und die Richtlinien des Internationalen Rates für die Harmonisierung der technischen Anforderungen an Humanarzneimittel (ICH).

Validation in the pharmaceutical industry in action

To bring the concept of validation to life, let's look at a real-world application. In a packaging context, consider the Locked4Kids Wallet Box: a child-resistant solution. Before this innovative packaging hits the market, it undergoes rigorous testing and validation to ensure it meets safety standards while being accessible to adults. This kind of validation includes tests to verify that the packaging is tamper-evident, durable, and functions as intended. For example, the testing was to see how fast both children and seniors could open the Wallet Box. The system proved difficult to open for children, while seniors could open it with ease.

Die Notwendigkeit einer kontinuierlichen Validierung

Validation in the pharmaceutical industry is not a one-time event but a continuous process. As new data are gathered, processes might be refined, and validation activities will be carried out again to ensure continuous compliance and quality. Validation in pharma is therefore viewed as an ongoing activity throughout the entire product lifecycle. After initial validation, processes must be continuously monitored using data from routine production to confirm that they remain in a state of control. This ongoing approach enables manufacturers to detect trends, deviations, or potential risks at an early stage and to take timely corrective or preventive actions. Regulatory authorities such as the FDA and EMA expect this lifecycle-based validation strategy, as it supports Good Manufacturing Practices, strengthens process understanding, and ultimately helps safeguard consistent product quality and patient safety.

Herausforderungen und Überlegungen

Die Validierung kann komplex sein, und zu den Herausforderungen gehören die Integration neuer Technologien, die Anpassung an sich ändernde Vorschriften und die Verwaltung der mit der Validierung verbundenen Kosten.

It is a vital part of the pharmaceutical industry's commitment to delivering safe and effective products and a dynamic process that requires attention to detail, a thorough understanding of processes, and a commitment to quality. Understanding the importance of validation is essential for anyone involved in the pharmaceutical industry, from the lab to the boardroom.
