Standard Operating Procedure for Stability Testing of Gels
1) Purpose
The purpose of this SOP is to establish procedures for conducting stability testing of gels in the pharmaceutical industry to evaluate their shelf-life, storage conditions, and stability characteristics.
2) Scope
This SOP applies to all personnel involved in conducting and overseeing stability testing of gels within the pharmaceutical production facility.
3) Responsibilities
Stability Study Coordinator: Manage and coordinate stability testing activities as per this SOP.
Quality Assurance (QA) Personnel: Review and approve stability protocols and study results.
Production and Quality Control (QC) Teams: Provide samples and support as required for stability testing.
4) Procedure
4.1 Protocol Development
4.1.1 Develop a stability protocol outlining the testing conditions, duration, and parameters to be evaluated (e.g., physical, chemical, microbial stability).
4.1.2 Obtain approval for the stability protocol from QA and relevant stakeholders.
4.2 Sample Preparation
4.2.1 Collect representative samples of the gel from each batch according to the sampling plan.
4.2.2 Document sample collection details including batch number, date of collection, and storage conditions.
4.3 Storage Conditions
4.3.1 Place samples in stability chambers or conditions as specified in the protocol (e.g., temperature, humidity).
4.3.2 Monitor storage conditions continuously and record environmental parameters regularly.
4.4 Testing Schedule
4.4.1 Conduct testing at defined time points (e.g., 0, 3, 6, 9, 12 months) as per the stability protocol.
4.4.2 Perform physical, chemical, and microbiological tests according to approved testing methods.
4.5 Data Analysis
4.5.1 Analyze stability data including results of tests such as viscosity, pH, microbial limits, and preservative efficacy.
4.5.2 Evaluate trends and deviations from initial specifications to determine shelf-life and storage recommendations.
4.6 Reporting
4.6.1 Prepare stability study reports summarizing all data, observations, and conclusions.
4.6.2 Include recommendations for storage conditions and shelf-life based on stability study findings.
