A tablet press in operation An old rotary tablet press. A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A tablet press can be used to manufacture tablets of a wide variety of materials, including pharmaceuticals, nutraceuticals, cleaning products, industrial pellets and cosmetics.
For compression testing, the analyst generally aligns the tablet in a repeatable way, [2] and the tablet is squeezed between a fixed and a moving jaw. The first machines continually applied force with a spring and screw thread until the tablet started to break. [3] When the tablet fractured, the hardness was read with a sliding scale. [3]
The compression is done either by a single-punch machine (also called stamping press, achieves an output of approximately 200 tablets per minute, making it ideal for manufacturing small batches of tablets) or by a multi-station machine (rotary press). The tablet press is a high-speed mechanical device.
Data relating to CPP should be recorded, stored, and analyzed by the manufacturer. CPP variables and ranges should be reevaluated after careful analysis of historical CPP data. Identifying CPPs is done in stage one of process validation: process design are an essential part of a manufacturing control strategy.
Process validation is the analysis of data gathered throughout the design and manufacturing of a product in order to confirm that the process can reliably output products of a determined standard. Regulatory authorities like EMA and FDA have published guidelines relating to process validation. [ 1 ]
Process qualification is the qualification of manufacturing and production processes to confirm they are able to operate at a certain standard during sustained commercial manufacturing. Data covering critical process parameters must be recorded and analyzed to ensure critical quality attributes can be guaranteed throughout production. [1]
Continued process verification (CPV) is the collection and analysis of end-to-end production components and processes data to ensure product outputs are within predetermined quality limits. In 2011 the Food and Drug Administration published a report [ 1 ] outlining best practices regarding business process validation in the pharmaceutical ...
A VMP is the foundation for the validation program and should include process validation, facility and utility qualification and validation, equipment qualification, cleaning and computer validation. It is a key document in the GMP ( Good manufacturing practice ) regulated pharmaceutical industry as it drives a structured approach to validation ...
