Standard Operating Procedure for Use of Binders in Granules Production

1) Purpose

The purpose of this SOP is to provide guidelines for the proper use of binders in the granulation process during pharmaceutical manufacturing. Binders are crucial for ensuring cohesive granules that can be further processed into tablets or capsules.

2) Scope

This SOP applies to all personnel involved in the granules production within the pharmaceutical manufacturing department, particularly those handling and using binders.

3) Responsibilities

Production Operator: Responsible for adding binders as per batch requirements and following SOPs.
Quality Control (QC) Analyst: Responsible for monitoring granulation parameters related to binder usage and conducting quality checks.

4) Procedure

1. Binder Selection:
   1. Consult the formulation or process development team to determine the suitable binder based on product requirements.
   2. Verify the availability and suitability of the selected binder for the intended granulation process.
2. Preparation and Addition of Binder:
   1. Prepare the binder solution or dispersion according to the specified concentration and method (e.g., aqueous or organic solvent).
   2. Add the binder solution to the dry powder blend gradually while mixing to achieve uniform distribution.
3. Granulation Process:
   1. Proceed with granulation using the chosen technique (e.g., wet granulation, dry granulation) following the standard procedures.
   2. Monitor granulation parameters such as binder incorporation rate, granule size, and moisture content to ensure consistency.
4. Post-Granulation Checks:
   1. Inspect the granules for desired characteristics such as hardness, friability, and flow properties.
   2. Conduct dissolution or disintegration tests if applicable to evaluate binder effectiveness.
5. Cleaning and Maintenance:
   1. Clean the equipment used for binder preparation and addition to prevent contamination.
   2. Perform routine maintenance as per equipment manufacturer’s guidelines.
