Complete Guide to Process Validation in Pharmaceutical Manufacturing 1. Introduction to Process Validation Process validation is a critical and mandatory component of pharmaceutical manufacturing. It ensures that a manufacturing process consistently produces products that meet pre-established quality criteria. Defined by the FDA as “the collection and evaluation of data, from the process design stage through commercial production,” process validation establishes documented evidence that a process is capable of consistently delivering quality outcomes. The importance of process validation is underscored by its direct link to patient safety, product efficacy, and regulatory compliance. Over the past decade, the approach to process validation…

How to Design a Pharmaceutical Process: Step-by-Step Approach How to Design a Pharmaceutical Process: Step-by-Step Approach Process validation is an essential aspect of pharmaceutical manufacturing that ensures processes are capable of consistently delivering products that meet quality standards. The validation process is regulated in different jurisdictions, including the US and EU, where organizations must align with FDA Process Validation Guidance, EU GMP Annex 15, ICH Q8-Q10 standards, and others. This article will guide you through the step-by-step lifecycle of process validation, including process design, qualification, and ongoing verification, helping QA, QC, validation, and regulatory teams gain a thorough understanding of…

Identifying Critical Quality Attributes (CQAs) and CPPs in Stage Identifying Critical Quality Attributes (CQAs) and CPPs in Stage In the highly regulated pharmaceutical industry, in-depth validation processes are essential for ensuring that products meet predefined quality standards. Understanding how to identify Critical Quality Attributes (CQAs) and Critical Process Parameters (CPPs) is fundamental. ISO 11135 plays a significant role in defining these attributes during the process design stage. This article presents a step-by-step tutorial aimed at professionals in QA, QC, Validation, and Regulatory teams across the US, UK, and EU. Step 1: Defining User Requirements Specification (URS) and Risk Assessment The…

Process Design Phase Explained: Linking QbD to Validation Process Design Phase Explained: Linking QbD to Validation Step 1: Understanding User Requirements Specification (URS) & Risk Assessment The User Requirements Specification (URS) is a critical element in the validation lifecycle. It serves as the foundation for process design by defining what stakeholders require from the process, including any specific expectations regarding product quality, regulatory compliance, and operational efficiency. The URS should provide a detailed account of functional requirements, user needs, constraints, and compliance needs regarding industry standards, including ISO 11135, which pertains to sterilization of healthcare products. Once the URS is…
