Photostability

All companies developing or manufacturing pharmaceutical drugs, require a robust photostability testing process to ensure product quality and regulatory compliance. Inadequate testing can result in costly delays and lost revenue.

At Q1 Scientific, we understand that maintaining the efficacy and safety of your drug substances and products is paramount. Our photostability testing services, adhering to the ICH Q1B guidelines, provide reliable data on how your products react to light exposure, ensuring they meet the highest standards.

Achieve Regulatory Compliance with Q1 Scientific's Photostability Solution

Regulatory Compliance


We adhere to the ICH Q1B guideline, conducting photostability testing on a single batch of material to provide reliable data on how your drug substance or product reacts to light exposure. This helps you meet regulatory requirements and avoid compliance issues.

 

Proactive Quality Assurance


Whether performing forced degradation or confirmatory studies, data from our fully qualified, temperature and humidity-controlled photostability chambers helps you take proactive steps to ensure product quality.

 

Consistent Light Exposure


We expose your samples side-by-side to guarantee consistent light exposure, ensuring accurate and reliable results.

 

Precise Testing Duration


Samples are exposed for the precise duration required to meet ICH Q1B standards, including:

  • Illumination of not less than 1.2 million lux hours (equivalent to 2 to 3 days’ exposure close to a sunny window in the summer).
  • Integrated near UV energy (320 nm to 400 nm: UVA) of not less than 200 watt hours per square meter (equivalent to 1 to 2 days close to a sunny window).

 

Accurate Monitoring


We use calibrated radiometers and lux meters to monitor light exposure accurately, ensuring the integrity of your data.

 

Thermal Change Assessment


If specified, we place dark controls (wrapped in aluminium foil) alongside your samples to assess any thermally induced changes.

 

Detailed Reporting


We generate a detailed graph that confirms light exposure over time, providing you with clear and comprehensive data.
