Expiry Date Justification Testing
In the pharmaceutical sector, ensuring product quality and safety is paramount. Expiry date justification testing plays a critical role in validating that products remain stable and effective up to their stated expiration dates. This service involves rigorous laboratory analysis to determine whether a drug substance or formulation maintains its chemical integrity, physical properties, and efficacy over time.
The primary objective of expiry date justification is to provide scientific evidence supporting the claimed shelf life of a pharmaceutical product. Regulatory bodies such as the FDA and EMA require this data to ensure that drugs remain safe and effective throughout their intended storage period. This testing is essential for manufacturers to meet regulatory compliance requirements, protect patient safety, and maintain market confidence.
The process begins with defining the test conditions, including temperature, humidity, light exposure, and time duration. These parameters are chosen based on real-world scenarios that the product might encounter during storage and distribution. For instance, a drug may be exposed to high temperatures in transit or stored in humid environments for extended periods.
During testing, samples are subjected to accelerated aging conditions designed to simulate long-term exposure over time. This allows researchers to predict how the product will behave under typical storage conditions without waiting years for natural degradation to occur. By using controlled environmental chambers that mimic various climates and stresses, we can accelerate the aging process while maintaining accurate data.
After exposing samples to these accelerated conditions, our team conducts extensive analysis across multiple parameters such as potency, purity, stability, and dissolution rate. We employ advanced analytical techniques like high-performance liquid chromatography (HPLC), Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC) to assess the chemical composition and physical state of the drug.
The results are compared against baseline data collected at the start of the test. Any significant changes from these standards indicate potential issues with product stability. Our team then interprets this information to determine if the product can safely be used beyond its initial expiry date as stated on packaging.
This testing ensures that manufacturers have robust evidence supporting their claims about shelf life, which is crucial for maintaining regulatory compliance and ensuring patient safety. It also helps companies avoid unnecessary waste by extending the useful life of stable products when appropriate.
