Sampling and Analysis of Pivotal Tablet Batches for Stability Studies
Purpose
The purpose of this Standard Operating Procedure (SOP) is to describe the procedures for sampling and testing pivotal batches of tablet dosage forms. This ensures that stability studies are conducted under controlled and reproducible conditions, generating reliable data for regulatory submission.
Scope
This SOP applies to all pivotal batches of tablet dosage forms that are subjected to stability testing within the facility.
Responsibilities
- Stability Manager: Ensure proper execution of sampling and testing procedures and compliance with regulatory guidelines.
- Stability Technicians: Perform sampling and testing as specified and document results accurately.
- Quality Assurance (QA) Team: Review and approve sampling and testing procedures and ensure adherence to regulatory standards.
Procedure
- Preparation for Sampling:
- Ensure all necessary sampling equipment and containers are clean and suitable for use.
- Label sampling containers with batch information, sampling date, and storage conditions.
- Sampling Procedure:
- Identify the pivotal batches for sampling based on the stability protocol.
- Randomly select samples from different locations within the batch to ensure representativeness.
- Collect the required number of tablets as specified in the stability protocol.
- Place the samples into the labeled containers, ensuring no contamination occurs.
- Testing of Samples:
- Perform initial testing on the samples to establish baseline data at time zero (To).
- Conduct the following tests on the sampled tablets:
- Appearance
- Weight variation
- Disintegration
time
Dissolution profile
Assay of active ingredients
Related substances/impurities
Moisture content (if applicable)
Record all test results in the appropriate laboratory notebooks and databases.

Quality Control:
Storage of Samples:
- Document the sampling process, including the batch number, sampling date, and sample quantities.
- Maintain detailed records of all tests performed, including methods, results, and observations.
- Ensure all documentation is reviewed and approved by the Stability Manager and QA Team.
- Investigate any deviations from the specified procedures or unexpected results.
- Document the deviation, including the date, time, personnel involved, and potential impact on the study.
- Implement corrective actions to address the root cause and prevent recurrence.
- Record corrective actions taken and review effectiveness.
- Perform a final review of the sampling and testing data to ensure accuracy and completeness.
- QA Team to conduct periodic audits of sampling and testing records for compliance.
- Store the remaining stability samples under specified conditions in stability chambers.
- Ensure proper organization within the storage units by study, batch, and time point.
