Types of validation in the pharmaceutical industry: a guide

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 process validation and its practical applications in the pharmaceutical industry.

How to define process validation?

Validation 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.

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.

Types of validation in pharma

1.    Process validation

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.    Cleaning validation

This ensures that cleaning methods effectively remove residues, contaminants or microorganisms from equipment to prevent cross-contamination. Cleaning validation is particularly critical for multi-product facilities.

3.    Analytical method validation

Verifies the accuracy, specificity, reproducibility and robustness of methods used to test pharmaceutical products. Compliance with ICH Q2(R2) is required for this process.

4.    Equipment validation

Confirms that equipment operates consistently within required parameters and supports the production of quality products. This includes qualification stages such as Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).

Often, the terms qualification and validation are used inter. However, they servedifference purposes in pharmaceutical manufacturing.

-         Qualification focuses on ensuring that equipment, systems, or facilities function as expected. This includes activities such as Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).

-         Validation, 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.

This distinction is crucial for understanding the steps involved in ensuring product quality and compliance with regulatory requirements.

Las etapas de la validación de procesos

Validation in the pharmaceutical industry typically follows a systematic approach:

• ‍Calificación del diseño(DQ)

Este paso inicial garantiza que el diseño propuesto del equipo o proceso cumple los requisitos para el fin previsto.

• Cualificación de la instalación (IQ)

En esta fase se confirma que los equipos o sistemas están instalados correctamente y según las recomendaciones del fabricante.

• Cualificación operativa (OQ)

Aquí se determina si los sistemas y equipos funcionan de acuerdo con los rangos de funcionamiento previstos.

• Cualificación del rendimiento (PQ)

El último paso consiste en comprobar que el equipo funciona de acuerdo con los parámetros del proceso y puede producir el resultado deseado.

La importancia de un enfoque sistemático

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'sabout guaranteeing the quality and consistency of life-saving drugs inqualitative healthcare packaging. That's why EcoBliss isyour partner in healthcare packaging.

Validation and its role in quality assurance

La validación es parte integrante de la Garantía de Calidad (GC) en la industria farmacéutica. Es una medida proactiva que identifica posibles problemas antes de que afecten al producto final. Se trata de un enfoque preventivo más que reactivo, que ahorra a las empresas costosas retiradas del mercado y mantiene su reputación.

Entorno normativo

There quirement for validation is grounded in regulations such as the FDA's Current Good Manufacturing Practices (discover why GMP matters, the European Medicines Agency's (EMA) guidelines, and the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH)guidelines.

Validación en acción

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.

La necesidad de una validación continua

La validación no es un acontecimiento puntual, sino un proceso continuo. A medida que se recopilen nuevos datos, los procesos podrán perfeccionarse y las actividades de validación volverán a llevarse a cabo para garantizar el cumplimiento y la calidad continuos.

Retos y consideraciones

La validación puede ser compleja, y algunos de los retos son la integración de nuevas tecnologías, la adaptación a la evolución de la normativa y la gestión de los costes asociados a las actividades de validación.

Es una parte vital del compromiso de la industria farmacéutica de ofrecer productos seguros y eficaces, y un proceso dinámico que requiere atención al detalle, un conocimiento profundo de los procesos y un compromiso con la calidad. Comprender la importancia de la validación es esencial para cualquier persona implicada en la industria farmacéutica, desde el laboratorio hasta la sala de juntas.
