Standard Operating Procedure for Product Release Testing for Gels
1) Purpose
The purpose of this SOP is to establish procedures for conducting product release testing on gels to ensure they meet predefined quality specifications before release for distribution and use.
2) Scope
This SOP applies to the Quality Control (QC) department responsible for performing product release testing on gels manufactured at the pharmaceutical manufacturing facility.
3) Responsibilities
Quality Control (QC): Perform product release testing according to defined procedures and standards.
Quality Assurance (QA): Oversee the implementation of product release testing procedures and ensure compliance with SOPs and regulatory guidelines.
Production: Provide samples for product release testing and coordinate with QC for timely testing and release.
4) Procedure
4.1 Sample Collection
4.1.1 Collect representative samples from finished gel batches with documented batch/lot numbers and production records.
4.1.2 Ensure samples are labeled correctly and securely stored prior to testing.
4.2 Initial Inspection
4.2.1 Conduct visual inspection of samples for any signs of contamination, defects, or deviations from specifications.
4.2.2 Record observations and document initial inspection findings.
4.3 Physical Testing
4.3.1 Perform physical tests according to predefined specifications, including:
a) Appearance: Assess color, clarity, and consistency.
b) pH Testing: Measure pH using calibrated equipment.
c) Viscosity Testing: Determine viscosity using appropriate methods.
d) Homogeneity Testing: Verify uniform distribution of components.
4.4 Chemical Testing
4.4.1 Conduct chemical analysis to ensure active ingredient content meets specified limits.
4.4.2 Perform assay testing and evaluate results against acceptance criteria.
4.5 Microbiological Testing
4.5.1 Perform microbial limits testing to ensure gel batches meet microbiological safety standards.
4.5.2 Conduct sterility testing where applicable to verify absence of microbial contamination.
4.6 Packaging Integrity
4.6.1 Inspect packaging materials and containers for integrity and compliance with specifications.
4.6.2 Conduct leak testing of gel tubes and containers to ensure proper sealing.
4.7 Compliance Assessment
4.7.1 Compare test results against predefined acceptance criteria and specifications.
4.7.2 Document compliance or non-compliance with release criteria.
4.8 Release Decision
4.8.1 Review all testing data and inspection reports to make informed release decisions.
4.8.2 Obtain authorization from designated personnel for batch release or rejection based on compliance assessment.
4.9 Documentation and Reporting
4.9.1 Prepare detailed product release reports documenting test results, compliance status, and release decisions.
4.9.2 Maintain accurate records of all product release testing activities, including protocols, data sheets, and reports.
