WATER PURIFICATION -VALIDATION AND QUALIFICATION Establishing reliability of pharmaceutical water purification, storage, and distribution systems requires demonstrating control of the process through an appropriate period of monitoring and observation. Finished water is typically continuously produced and used, while product and process attributes may only be periodically assessed. The quality of bulk finished water cannot be established by…
Analytical Instrument Categories Users are establishing the level of qualification needed for an instrument. On the basis of the level needed, it is to categorize instruments into three groups: A, B, and C, as for detail defined below. Examples of instruments in each group are provided. Note that the list of instruments provided here is for illustration…
PILOT SCALE-UP AND PROCESS VALIDATION The development of the product before the preparation of the first pilot-production batch. The development activities are listed as follows: 1. Formulation design, selection, and optimization 2. Preparation of the first pilot-laboratory batch 3. Conduct initial accelerated stability testing 4. If the formulation is deemed stable, preparation of additional pilot…
WHAT IS PROCESS VALIDATION? The process validation is derived from the fact that the specific exercise of process validation should never be designed to fail. Failure in carrying out the process validation assignment is often the result of an incomplete or faulty understanding of the process’s capability, in other words, what the process can and…
