1. Understanding Why GMP Compliance is Incumbent:

To illustrate the importance of GMP compliance in Pharmaceuticals, let us consider a scenario involving a sterile area. Suppose there are several stages involved in producing a batch of medicine, such as sourcing active pharmaceutical ingredients, releasing quality control materials, storing them in the warehouse, dispensing them for batch manufacturing, mixing the batch, releasing water QC, filling the containers, and sterilizing them. Obviously, each stage must adhere to GMP standards. However, if there is any deviation or noncompliance in GMP checks at any point, the entire batch will be contaminated and could cause the death of as many patients as the batch size.

Imagine for a moment, if a contaminated batch of 100,000 ampules is distributed to the market and administered to 100,000 patients. This would surely cause their condition to deteriorate or even death. The only certain alternative will be to recall and destroy the entire batch. Moreover, it will result in the waste of resources and damage to the reputation. Therefore, GMP is essential
