Good manufacturing practice is an essential part of the production of human drugs, veterinary drugs, biological and biotechnology products, and pharmaceutical ingredients. These commercial processes are subject to regulatory oversight and must ensure that every aspect of the production process is carefully scrutinized. The purpose of process validation is to collect data and scientifically analyze the production process from conception to large scale production. An updated process validation protocol is essential to ensuring product quality and consistency. Many laws have been established to mandate process validation in order to protect consumers, especially in the case of pharmaceutical products.
