Labeling of Stability Samples

Each stability sample will be labeled with the following information:

• Product Name
• Batch Number
• Storage Condition
• Sampling Time Point

Storage Configuration

Stability samples will be stored in [describe the storage configuration, e.g., stability chambers, controlled temperature rooms].

Stress Testing

• Development Stability Study: [Insert Details]
• Pivotal/Bioequivalence Stability Study: [Insert Details]
• Validation/PM Stability Study: [Insert Details]

Reference Listed Drug (RLD) Stability

The Reference Listed Drug (RLD) will be placed on stability under the same conditions as the test product to provide a comparison for stability data.

Packaging Procedures

Stability samples will be packaged according to the following procedures:

• Use of primary and secondary packaging materials that simulate commercial packaging
• Sealing and labeling of packages to prevent contamination and mix-ups

Storage Condition Monitoring

Storage conditions (temperature and humidity) will be monitored continuously using calibrated data loggers. Deviations from specified conditions will be documented and investigated.

Calibration of Stability Chambers

Stability chambers will be calibrated regularly to ensure accurate and consistent storage conditions. Calibration records will be maintained and reviewed periodically.

Sampling and Testing

Sampling and testing of pivotal batches for various dosage forms (e.g., capsules, tablets, powders, syrups) will be conducted as per the study protocol.

Container-Liner-Closure Systems

The container-liner-closure systems used in the stability study will be certified for compatibility and integrity to ensure product stability.

Reporting Test Results

All test results will be documented and reported in a timely manner. Any abnormal or out-of-specification (OOS) results will be investigated according to established procedures.

Handling Stability Chamber Breakdowns

In the event of a stability chamber breakdown or storage condition deviation, the following procedures will be followed:

• Document the deviation and the duration of the breakdown
• Investigate the impact on the stability samples
• Take corrective actions and document the findings

Climatic Condition Recording

Climatic conditions (temperature and humidity) will be recorded regularly and reviewed to ensure compliance with specified conditions.

Review and Control of Temperature and Humidity Recording Charts

Temperature and humidity recording charts will be reviewed periodically to identify any deviations and ensure control measures are in place.

Periodic Revalidation

Climatic rooms and chambers will be revalidated periodically to ensure they maintain the specified conditions consistently.

Sanitation and Housekeeping

Sanitation and housekeeping requirements for climatic chambers will be followed to prevent contamination and maintain a controlled environment.

Photostability Study

Photostability studies will be conducted according to ICH guidelines to assess the effect of light exposure on product stability. Procedures for the operation and calibration of photostability chambers, lux meters, and UV meters will be followed.

Freeze Thaw Studies

Freeze thaw studies will be conducted to evaluate the stability of the product under cycles of freezing and thawing. The procedure will include preparation, freeze thaw cycles, post-cycle testing, and documentation.
