Standard Operating Procedure for Stability Testing of Ophthalmic Ointments
1) Purpose
The purpose of this SOP is to provide a standardized procedure for conducting stability studies on ophthalmic ointments to ensure they maintain their potency, sterility, and physical characteristics throughout their shelf life.
2) Scope
This SOP applies to all ophthalmic ointments manufactured, tested, or stored within the facility. It is relevant to departments involved in production, quality control, quality assurance, and regulatory compliance.
3) Responsibilities
- Quality Control (QC) Team: Conducts stability testing, including sterility, potency, and physical examination (e.g., viscosity, particle size).
- Quality Assurance (QA) Team: Reviews and approves
stability study protocols and reports.
Production Team: Provides necessary samples and maintains proper documentation of production records.
4) Procedure
- Sample Preparation
- Obtain representative samples of ophthalmic ointments from production batches.
- Store samples under appropriate conditions until stability testing begins.
- Design of Stability Study
- Prepare a protocol outlining storage conditions, test intervals, and analytical methods (e.g., sterility testing, viscosity testing).
- Submit the protocol for approval by the QA and Regulatory Affairs teams.
- Execution of Stability Study
- Store samples in designated stability chambers under controlled conditions (e.g., 25°C/60% RH).
- Perform tests at each interval to evaluate sterility, potency, and physical characteristics.
- Record all test results, observations, and any deviations from the protocol.
- Data Analysis and Reporting
- Analyze the data to determine any changes in the product’s sterility, potency, or physical characteristics over time.
- Prepare a detailed stability study report and submit it to the QA team for review and approval.
