1. Purpose
To establish a uniform procedure for dispensing of raw materials intended for the manufacturing of subcutaneous (SC) injections. This ensures correct quantity, proper handling, and documentation in compliance with
GMP, WHO, and ICH guidelines.
2. Scope
This SOP covers all dispensing operations for active ingredients and excipients used in the formulation of subcutaneous injection products at the Sterile Injectable Manufacturing department.
3. Responsibilities
- Store Executive: Handles material weighing and initial verification.
- QA Officer: Monitors compliance with SOP and signs off on dispensed materials.
- Production Chemist: Verifies and receives dispensed materials.
- QC Personnel: Verifies CoA and material suitability before release.
4. Accountability
The Head of Manufacturing is accountable for ensuring the implementation of this SOP and training of all related personnel.
5. Procedure
5.1 Material Request and Verification
- Receive MRN from production with batch number, material details, and quantity.
- Verify storage conditions, integrity of containers, and label clarity.
- Cross-check material expiry, status label, and CoA availability.
5.2 Weighing Area Preparation
- Ensure the RLAF unit is functioning and area is cleaned.
- Place cleaned and calibrated weighing balances in position.
- Sanitize outer surfaces of all containers with 70% IPA.
5.3 Dispensing Operations
- Weigh each raw material individually under RLAF using pre-cleaned containers.
- Use separate spatulas/scoops for each material to prevent contamination.
- Record details in Material Dispensing Log (Annexure-1) immediately after weighing.
- Ensure weighing accuracy within permissible limits of ±0.1%.
5.4 Labeling and Documentation
- Affix label on each container with material name, quantity, batch number, date of dispensing, and operator signature.
- Fill the Approval and Release Form (Annexure-3) and submit to QA.
- Maintain traceability through batch linkage to MRN and BMR.
5.5 QA Review and Release
- QA Officer checks container labels, quantities, and documentation.
- Signs the release section and authorizes transfer to staging area.
- Release approved materials to production with acknowledgment.
