Stability Testing

Under ICH Q1A guidelines, adopted by the FDA and EMA, stability testing is intended to demonstrate how the quality of a drug substance varies with time under a variety of environmental stresses. Stresses that are commonly used for stability testing include temperature, humidity, and light.

Stability testing is also used as a verification process for packaging and packaged goods. It can also establish a re-test period for active pharmaceutical ingredient or a shelf life for the medicinal product and recommended storage conditions.

ICH Q1A - Stability Testing of New Drug Substances and Products

  • This guidance is intended to define what stability data package for a new drug substance or drug product is sufficient for a registration application within the three regions of the European Union (EU), Japan, and the United States. It does not seek to address the testing for registration in or export to other areas of the world. The guidance exemplifies the core stability data package for new drug substances and products, but leaves sufficient flexibility to encompass the variety of different practical situations that may be encountered due to specific scientific considerations and characteristics of the materials being evaluated. Alternative approaches can be used when there are scientifically justifiable reasons.
