SOP for Primary Drying Process in Lyophilization

Standard Operating Procedure for Primary Drying Process in Lyophilization

1) Purpose

This SOP outlines the steps involved in the primary drying (sublimation) stage of lyophilization to ensure the effective removal of ice from the product while preserving its structure and quality.

2) Scope

This SOP applies to operators, formulation scientists, and QA personnel involved in the lyophilization process, particularly during the primary drying phase.

3) Responsibilities

Operators: Responsible for initiating and monitoring the primary drying phase according to the Batch Manufacturing Record (BMR).
QA Personnel: Responsible for verifying the primary drying parameters and ensuring product quality is maintained.

4) Procedure

4.1 Primary Drying Setup

4.1.1 Pre-Drying Checks

4.1.1.1 Ensure that the shelves are pre-cooled to the appropriate temperature before initiating the primary drying phase.
4.1.1.2 Verify that the vacuum pump is operational and capable of maintaining the required vacuum level throughout the drying phase.

4.2 Monitoring Sublimation

4.2.1 Temperature and Pressure

4.2.1.1 Monitor the chamber pressure and ensure it remains within the specified range for effective sublimation of ice from the product.
4.2.1.2 Monitor the product temperature and ensure that it remains below the collapse temperature to preserve product structure.

4.2.2 Sublimation Rate

4.2.2.1 Adjust the shelf temperature and vacuum level as necessary to control the rate of

sublimation and prevent product degradation.

4.3 Documentation

Record all temperature and pressure readings during the primary drying phase in the Primary Drying Logbook. Any deviations from the process parameters must be documented and approved by QA.

SOP for Secondary Drying Process in Lyophilization

Standard Operating Procedure for Secondary Drying Process in Lyophilization

1) Purpose

This SOP outlines the steps involved in the secondary drying (desorption) stage of lyophilization, aimed at removing residual moisture from the product to ensure long-term stability.

2) Scope

This SOP applies to operators, formulation scientists, and QA personnel responsible for lyophilization, particularly during the secondary drying phase.

3) Responsibilities

Operators: Responsible for initiating and monitoring the secondary drying phase according to the Batch Manufacturing Record (BMR).
Formulation Scientists: Responsible for ensuring the product reaches the desired residual moisture content without degradation.
QA Personnel: Responsible for verifying drying parameters and ensuring product quality.

4) Procedure

4.1 Secondary Drying Setup

4.1.1 Pre-Drying Checks

4.1.1.1 Ensure that the lyophilizer chamber is ready for secondary drying, with the product adequately frozen from the primary drying phase.
4.1.1.2 Confirm that the shelf temperature is set to the desired level for desorption of bound water without damaging the product.

4.2 Monitoring the Drying Process

4.2.1 Temperature and Pressure Control

4.2.1.1 Monitor the shelf temperature throughout the secondary drying phase to ensure it remains within the specified range for efficient moisture desorption.
4.2.1.2 Monitor chamber pressure to ensure proper vacuum conditions are maintained for the drying process.

4.2.2 Residual Moisture Monitoring

4.2.2.1 Periodically check the product’s residual moisture content using suitable analytical techniques to ensure it meets the specified limits.

4.3 Documentation

Record all temperature, pressure, and moisture readings in the Secondary Drying Logbook. Any deviations from the specified process parameters must be reported to QA and addressed before proceeding.
