ICH Guidelines

When it comes to pharmaceuticals, the stability of drug substances is required testing through The International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH). The ICH helps establish the universal set of quality standards in the pharmaceutical industry.

Stability testing is important and helps determine factors such as:

  • Shelf life
  • Retest periods
  • Optimal storage conditions

Q Laboratories stores stability test samples in ICH compliant humidity and temperature-controlled chambers.

Why Is It Important?

Stability testing is important for a variety of reasons. Not only does it help determine critical factors about a product to promote quality, but it can also help determine optimal storage conditions for a given substance – providing valuable insight to ideal product packaging and label instructions.

Types of Stability Testing (Long term, accelerated, freeze/thaw, thermal cycle)

Stability testing subjects a substance to a variety of environmental conditions to determine if the compound may change in a harmful way to the consumer. Since it is unlikely for a product to stay in the exact same environment it was created in for its lifetime, it’s extremely important to test that product.

Other important discoveries during a stability test are the retest period, or the time in which the product should be subjected to stability testing again. This time period establishes the time frame the substance is expected to remain within its required quality specification to be used in the manufacturing of a drug product. Once a retest period has elapsed, a substance is required to meet acceptance criteria before being used in a product for consumer use. Learn more here.

Arguably, the most important outcome for stability testing is determining overall quality & safety for consumers over the lifetime of the product.

What Are The Types? (Long-term, accelerated, freeze/thaw, thermal cycle)

Since Stability Testing can be conducted on a range of products and substances, in a range of environments, there are a variety of tests that can be performed. Some of the types of tests we do are:

  • Identification tests
  • Physical tests
  • Assays
  • Microbiological tests
  • Weight loss
  • Preservative effectiveness tests 

Prior to any study, acceptance criteria are established. Quality is key, so it’s important to ensure an accurate test to ensure reliable results.
