Explain the Water systems in pharmaceutical plant.
Answers
Pharmaceutical Water is, perhaps, the most important of all pharmaceutical utilities. It is used as an excipient in many pharmaceutical formulations, as a cleaning agent, and as a separately packaged product diluent. In addition to non-compendial systems, pharmaceutical facilities typically include systems for delivering pharmacopoeial Purified Water (PW) Water for Injections (WFI), and Highly Purified Water (HPW).
This classroom course has been substantially updated to feature the guiding principles of the ISPE Baseline Guide: Water and Steam Systems (Second Edition) with particular emphasis placed upon microbial control and laboratory water as well as key design philosophies. The principles of design and operation of water systems used directly in pharmaceutical manufacturing and laboratory applications, including the essential concepts and principles of systems used to generate USP, EP and non-compendial waters will be covered. These concepts include specification, design, operation, testing, and maintenance of equipment and systems for water generation.
Participants will examine methods for proper water quality selection and receive detailed guidance regarding the choice and use of appropriate construction materials and instrumentation. Particular attention will be paid to system and component sanitisation procedures and microbial control while participants will receive guidance regarding appropriate monitoring programmes during ongoing operation as well as during initial system qualification.
The course will also cover regulatory requirements including USP, EP, and JP Monographs, the USFDA Guide to Inspections of High Purity Water Systems, current FDA views, and current Good Manufacturing Practice (cGMP) requirements. Common water system myths will also be explored and a variety of practical system designs will be evaluated for EP, EMA, USP and FDA compliance, as well as their advantages and disadvantages. Particular attention will be paid to system and component sanitization procedures and microbial control.
Additional content from the ISPE Good Practice Guide: C&Q of Water and Steam Systems (Second Edition) will include the risk assessment and risk mitigation process used during design and qualification is crucial to ensuring product quality, allowing system designers and operators to gain process understanding of those product/process quality attributes which affect water or steam quality. The course will use a risk assessment example to determine the critical aspects, definition of critical quality attributes/critical process parameters (CQA/CPP), and identification/appropriate execution of quality indicating verification activities applied throughout the Validation Life Cycle. The course will include discussion of the upcoming European Pharmacopoeia regulatory change allowing alternative WFI production methods in addition to distillation. The change will align EP requirements closely with USP WFI production methods opening opportunities for membrane-based systems. The course will also include material from the new ISPE Good Practice Guide: Sampling for Pharmaceutical Water, Steam and Process Gases and will review optimizing sampling plans to significantly reduce operational costs.
Examples of a science and risk-based risk-management process for water and steam systems and typical system boundaries and critical aspects examples are discussed. Information is provided on the URs, FS, and how a QbD approach including Critical Aspects (CA) – CQAs and CPPs may be implemented. The module provides an alternative “science and risk-based” method that can be applied to the qualification of GMP water and steam systems
Hey mate!
I am here with your answer!
Water is a component of every pharmaceutical product, so water system must be validated to ensure the consistent production of high quality water. The continuous monitoring of water system is an unequivocal regulatory requirements and a major cost strain on company personnel and resources.
Water is the most widely used substance, raw material or starting material in the production, processing and formulation of pharmaceutical products.
Hope this will help you!
