Process Validation in Pharmaceutical Industry: A Lifecycle Approach as per Regulatory Guideline

Abstract

Process validation represents one of the key components of quality assurance in the pharmaceutical industry for providing the consistency in manufacturing products of a predetermined quality. The process of validation includes gathering and analyzing information throughout the development and implementation of processes in order to verify the capability of these processes to produce products of required quality characteristics. The process validation methodology has considerably transformed due to the introduction of the concept of the lifecycle approach by the regulators, for example, FDA.

FDA’s guidelines for process validation released in 2011 indicate the need for a lifecycle validation process that involves three stages: process design, process qualification, and process verification. The main purpose of process validation is not only to meet current Good Manufacturing Practices (cGMP) but also to improve product quality and mitigate potential manufacturing risks.

This review paper examines the concepts, categories, and lifecycle approach to process validation, as well as the regulatory aspects provided by the FDA and others. In addition, the significance of quality assurance and risk-based approaches in enhancing process robustness is emphasized.
