What is the Origin of Stress Testing?

The concept is an adaptation of 'stress testing' from engineering principles, applied to the chemical integrity of a pharmaceutical product. It became a formalized regulatory requirement to ensure comprehensive understanding of a drug's stability profile. This testing is mandated by global guidelines to ensure that the analytical methods used for routine quality control are capable of detecting all possible impurities.

What is the Mechanism of Stress Testing?

The procedure involves applying supra-normal levels of a stressor, which rapidly accelerates the degradation reactions that would occur slowly over time under normal storage conditions. By analyzing the resulting degradation products using highly sensitive analytical techniques, scientists can elucidate the compound's intrinsic degradation pathways. This information is essential for formulating a stable hormonal product and for validating the methods used to monitor its quality throughout its shelf life.

Stress Testing

Meaning

Stress Testing, in the context of pharmaceutical development, is a controlled laboratory procedure that subjects a drug substance or its final product to extreme environmental and chemical conditions, such as high heat, intense light, high humidity, or extreme pH. The deliberate goal is to force the drug to degrade and thereby identify its inherent stability characteristics and all potential degradation products. This is a critical part of quality assurance for all hormonal formulations.
