1 Review Article Pharmaceutical Process Validation: An Overview Md. Shoaib Alam* ABSTRACT. Research Scientist, PDL The goal of the CGMPs for the 21st Century initiative such as advancing Formulation, science and technological innovation. Update guidance based on regulatory Ranbaxy Lab Ltd, Paonta Sahib, experience since 1987. Process Validation emphasise on Process design Himachal Pradesh-173025 elements and maintaining Process control during commercialization and communicate that Process validation is an ongoing program and align J. Adv. Pharm. Edu. & Res. Process validation activities with product lifecycle. Process validation also emphasizes the role of objective measures and statistical tools & analyses and emphasizes knowledge, detection, and control of variability and gives assurance on consistent of quality/productivity throughout life cycle of product. Key words: Process Validation, Process Validation Decision Tree, Process Validation Stages, Validation Acceptance Criteria, Deviation INTRODUCTION careful and systemic attention to a number of Pharmaceutical Process Validation is the most importance factors, including: selection of quality important and recognized parameters of CGMPs.

2 Process through in- Process and end-product The requirement of Process validation appears of testing. [4]. the quality system (QS) regulation. The goal of a quality system is to consistently produce REGULATORY REQUIREMENTS FOR. products that are fit for their intended use. Process VALIDATION [1]. Process validation is a key element in assuring FDA regulation describing current good that these principles and goal are met. [1] The manufacturing practices (CGMPs) for finished Process validation is standardization of the pharmaceuticals are provided in 21 CFR parts validation documents that must be submitted 210 and 211. The CGMP regulations require that with the submission file for marketing manufacturing processes be designed and authorization.[2] The Process validation is controlled to assure that in- Process materials intended to assist manufacturers in and the finished product meet predetermined understanding quality management system quality requirements and do so consistently and (QMS) requirements concerning Process reliably.

The foundation assurance of product quality is derived from for Process validation is provided in Address for correspondence (a), which states that here shall be written Md.

The proof of validation is specifications ( (a)). The CGPM obtained through the collection and evaluation of regulations also provide norms for establishing data, preferably, beginning from the Process in- Process specifications as an aspect of Process development phase and continuing the validation.
