Equipment lyophilizer

The documents described, namely, System Qualification Procedures (SQPs) and Standard Operating Procedure (SOP) in Figure 1 contain a generic risk assessment for determination of the validation scope and effort on the equipment lyophilizer. They were also used as a generic validation master plan for the project. Management of the project resources, costs, and deadlines was performed with a model created in a standard project planner. 

The facilities comprise a long list of equipment for lyophilization and vacuum-drying, formulation, filling, and packing. Projects may concern product or process development, scaling up or direct manufacturing (pilot or commercial scale). 

Three vacuum systems are commonly used in modern aseptic manufacturing facilities (1) house vacuum systems, (2) vacuum systems dedicated to lyophilization equipment, and (3) vacuum systems dedicated to autoclaves or other sterilization equipment. 

To demonstrate the control of aseptic operations maintained by well-trained personnel, defined procedures, and appropriately designed equipment and facilities. Media filling in conjunction with comprehensive environmental monitoring will be conducted three times to demonstrate that the aseptic processing of lyophilized powder is functioning as intended. 

Replacement or addition of lyophilization equipment of a different size that uses different operating parameters or lengthens the overall process time. 

Until atmospheric spray-freeze-drying equipment becomes commercially available, the development of formulation will be mainly based on the Trial and Error approach, and the validation of the classical lyophilization procedure will remain difLcult. 

Validation of the lyophilizer cleaning and sterilization processes should be accomplished. Particular care should be taken to verify that there is no back-migration of contaminants, whether from adjuvant fluids integral to the equipment of by cross-contamination from previous product. Typically, an overkill approach using a sufficient number of thermocouples and biological indicators is the method of choice. Finally, fill testing to verify the adequacy of the sterilization procedure and the aseptic manipulations involved with product filling, transfers, and lyophilization needs to be performed. 

Equipment Qualification (EQ) is a useful endeavor when the lyophilizer is a complex and sophisticated system. Large-scale manufacturing units commonly include multiple automated support operations. These may include steam-in-... 

Activities within the FAT are complementary to that of the IQ and OQ implemented at the final installation site. This would include verification of the engineering documentation, construction, and assembly of the lyophilizer, along with demonstration of the equipment performance. 

The Installation Qualification consists of a description of the lyophilization equipment, a system hardware and component list, the documentation of the installation procedures, and the equipment start-up and operator training. The IQ also includes references to the purchase specifications, engineering review, and SOPs. The objectives are to assure that the equipment design and construction are appropriate for the intended use, it is installed properly, the utilities are suitable and adequate, and that procedures are in place for proper maintenance and operation. 

The description of the lyophilization equipment provides a general overview of the lyophilizer, the installation site, operation, and functions. The description also identifies the major components of the system. From the listing of the major... 

Documentation of the installation can also be included within the IQ section of the validation package. Part of this documentation may take the form of an installation checklist. This checklist would include each specific activity necessary for the installation of the lyophilizer, who completed and checked the work, and the date the work was completed. These activities would include assembly of the various lyophilizer parts (if dismantled at the factory for shipment) and the connection to utility supplies. In some circumstances, these activities and the associated documentation may have been completed during the commissioning of the equipment. 

Lyophilization processes consist of the manipulation of environmental conditions of subambient temperatures and subatmospheric pressures. These extraordinary conditions are created by the lyophilization equipment. The success of the process, therefore, relies heavily on the operating performance of the lyophilizer. Confidence in the ability of the equipment to create these necessary environmental conditions is achieved through the successful completion of a comprehensive IQ and OQ. Without the proper performance of the equipment, there is limited opportunity for successful processing of materials. 

Equipment operation is another category of these SOPs. This type of procedure is applicable to more complex types of equipment, but not to all. Obviously we would not need an operating procedure for a stainless steel tank, but would for a lyophilizer. These SOPs provide a detailed step-by-step sequence of operations to run a piece of equipment. They begin with equipment assembly, then operation, and finally equipment disassembly.
