FAQs

Here are some frequently asked questions about Stability Testing and Storage

What is stability testing?

Stability testing is a critical process in pharmaceutical development where drug products are evaluated under specific conditions over a set period to understand how time and environmental factors (such as temperature, humidity, and light) affect their quality, safety, and efficacy. The results are used to determine shelf life, storage conditions, and packaging requirements. Stability testing follows guidelines provided by regulatory authorities like the FDA and ICH (International Council for Harmonisation).

Why is stability testing important?

Stability testing is essential for ensuring the drug remains effective and safe throughout its intended shelf life. It helps identify the optimal storage conditions and packaging needs to maintain drug quality. Stability testing is also a regulatory requirement for obtaining marketing approval, as it provides evidence that the drug will perform as expected under normal storage conditions and until its expiration date.

What types of stability studies do you offer?

We offer a comprehensive range of stability studies, including:

  • Real-time stability testing: Assessing the product under recommended storage conditions for its anticipated shelf life.
  • Accelerated stability testing: Exposing the product to elevated conditions to speed up the aging process, predicting long-term stability.
  • Stress testing: Subjecting the product to extreme conditions to assess its robustness and identify degradation products.
  • Photostability testing: Evaluating the effect of light exposure on the product.
  • Freeze-thaw cycle testing: Assessing stability through cycles of freezing and thawing, important for products requiring cold chain logistics.
How do you determine the appropriate conditions for stability testing?

The appropriate conditions for stability testing are determined based on regulatory guidelines, the product's intended market, and specific attributes of the drug product. For example, ICH guidelines recommend specific temperature and humidity conditions for real-time and accelerated studies. The product's composition, formulation, and packaging can also influence the selection of testing conditions. Custom studies may be designed for products with unique requirements or for specific global markets with different climatic zones.

What is the significance of ICH guidelines in stability testing?

ICH guidelines provide a harmonized framework for stability testing, ensuring consistent and comprehensive evaluation of pharmaceutical products across different regions. These guidelines define the types of studies required, testing conditions, study durations, and documentation needed for regulatory submissions. Adhering to ICH guidelines helps ensure that a pharmaceutical product is evaluated rigorously and is likely to be accepted by regulatory authorities in ICH member countries, facilitating global market access.

Can you support stability testing for all types of dosage forms?

Yes, we can support stability testing for a wide range of dosage forms, including solid, semi-solid, liquid, and injectable products. Our facilities are equipped with a variety of controlled environment chambers that can simulate a broad spectrum of storage conditions. Our experienced team is adept at developing and executing stability protocols tailored to the unique requirements of each dosage form and its specific formulation characteristics.

What happens if a product fails stability testing?

 If a product fails stability testing, we conduct a thorough investigation to identify the root cause of the failure, which could be related to formulation, packaging, or storage conditions. Based on the findings, we may recommend formulation adjustments, alternative packaging solutions, or revised storage conditions. A new stability study is then initiated to confirm that the modifications address the stability issues. Our goal is to ensure that the product meets all quality and regulatory requirements before proceeding to market.

How are stability samples stored and monitored?

Stability samples are stored in controlled environment chambers that accurately maintain specified conditions of temperature and humidity. These chambers are continuously monitored with calibrated equipment to ensure consistent conditions throughout the study duration. Samples are periodically removed at predefined intervals and analyzed for physical, chemical, and microbiological stability indicators. Comprehensive records are maintained for each study to ensure traceability and compliance with regulatory standards.

How long does stability testing take?

The duration of stability testing varies depending on the type of study. Real-time stability studies typically follow the intended shelf life of the product, which could be 12 months, 24 months, or longer. Accelerated stability studies are shorter, often lasting 6 months. The actual timeline can also be influenced by the specific requirements of the regulatory submission and the need for intermediate testing points. Early phase development may utilize abbreviated stability studies to support initial filings, with more comprehensive testing conducted in parallel to support final product registration.

Do you provide stability storage services?

Yes, we provide comprehensive stability storage services, offering a range of controlled temperature and humidity conditions to meet ICH guidelines and custom requirements. Our storage facilities are designed to accommodate large and small-scale studies for a variety of pharmaceutical products. These services are complemented by our analytical testing capabilities, providing a complete solution for stability study execution and data analysis. We ensure that all stored products are managed under strict GMP conditions, with 24/7 monitoring and backup systems to guarantee sample integrity throughout the study duration.
