Pharmaceutical Stability Testing & Storage

In the ever-evolving world of pharmaceuticals, maintaining the integrity of products through controlled storage conditions is essential. Pharmaceutical stability storage plays a pivotal role in ensuring that drugs remain safe, effective, and compliant with stringent regulatory standards.

From precise temperature and humidity controls to adhering to international guidelines, this vital process encompasses a broad spectrum of factors. Learn more about pharmaceutical stability testing and storage below.

What is Pharmaceutical Stability Storage?

Pharmaceutical stability storage is a crucial aspect of the pharmaceutical industry that involves maintaining and storing pharmaceutical products under controlled temperature, humidity, and lighting conditions. The storage process helps ensure the quality, efficacy, and safety of pharmaceuticals throughout their shelf life.

Commonly used in various stages of drug development, stability storage plays a vital role in conducting stability tests. These tests are necessary to understand how different environmental factors affect the product over time. For instance, pharmaceutical companies often employ stability storage to test how a new drug will react to conditions like high humidity or varying temperatures. Doing so enables them to assess potential degradation, interactions, or any other changes that may occur over a specific period.

Stability storage is essential for the development phase and the ongoing quality control of pharmaceutical products. These controlled environments allow manufacturers, researchers, and regulators to guarantee that the drugs going to consumers meet all the required quality standards.


The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) provides guidelines that unify standards within the pharmaceutical industry. Among these guidelines, those related to stability testing and storage are particularly vital to ensuring the quality of pharmaceutical products.

The ICH Guidelines for stability testing, or the ICH Q1A through Q1F, aim to standardize the methods and conditions for stability testing of new drugs and other pharmaceutical products. These guidelines help manufacturers and regulators determine the appropriate shelf life and storage conditions for various medicines.

Some aspects of the ICH Guidelines for stability testing and storage include:

  • Stress Testing: This involves exposing the product to extreme conditions to determine its potential for degradation.
  • Long-Term Stability Testing: Assessing the product’s stability under the proposed storage conditions for extended periods.
  • Accelerated Stability Testing: Conducting tests at elevated temperatures and humidity to predict the product’s long-term stability.

Following these guidelines ensures that pharmaceutical companies conduct standardized, rigorous testing to understand and maintain the quality of their products. It fosters international collaboration and agreement on the best practices for stability testing and provides a robust framework that benefits the industry and patients who depend on these products.

Pharmaceutical Stability Testing & Storage Conditions

When it comes to pharmaceutical stability storage, precision and control are paramount. The ability to maintain specific conditions is vital, but the requirements can vary based on the particular pharmaceutical products. 

Exact temperature regulation is central to preserving pharmaceutical integrity. This can range from room temperature of 15°C to 40°C for general storage, to refrigerated conditions around 2°C to 8°C, or even freezing temperatures as low as -20°C for particular substances.

Along with temperature, controlling humidity is crucial in pharmaceutical stability storage. Relative humidity (RH) conditions such as less than 25% to 75% are common in pharmaceutical storage to manage moisture levels, preventing degradation or alteration of the product’s properties.

Pharmaceutical stability storage also requires robust systems for redundancy. With 100% redundant controls and conditioners, a consistent environment is maintained, and backup systems stand ready to engage if necessary. Automatic electric generator backup may also be in place to counter any power interruptions, safeguarding the pharmaceuticals’ integrity.

Finally, rigorous monitoring and adherence to regulations are integral to successful pharmaceutical storage. Facilities must comply with all relevant regulatory bodies, including the guidelines set by ICH, ensuring that essential data is logged, scrutinized, and aligned with global standards.

Pharmaceutical Stability Storage Solution

At the heart of the pharmaceutical industry is the need for precision and unwavering quality control. Our validated offsite cGMP (current good manufacturing practice) facility stands at the forefront of this critical function. We have meticulously designed this facility to meet Zones I – IV global submission requirements per ICH Harmonised Tripartite Guideline – Stability Testing of New Drug Substances and Products Q1A(R2), ensuring the highest standards in pharmaceutical stability storage.

We offer an array of off-site ICH storage conditions to cater to various pharmaceutical needs. For long-term and intermediate storage, we provide controlled environments of 25°C/40%RH, 25°C/60%RH, 30°C/65%RH, 30°C/75%RH, and 30°C/35%RH. These specific conditions facilitate the careful preservation and monitoring of pharmaceuticals, safeguarding their efficacy and quality over extended periods.

In addition to the standard conditions, our facility specializes in accelerated storage solutions at temperatures of 40°C with controlled humidity levels of not more than 25%RH and 40°C/75%RH. These conditions allow for rigorous testing of pharmaceutical products, simulating the effects of long-term storage in a shorter timeframe. We also offer specialized refrigerated and freezer 2 maintaining precise temperatures of 2°C – 8°C (5°C), -20°C, and -80°C LN2 vapor phase (-190C) to accommodate a diverse range of pharmaceutical products.
