1. Purpose

To define the procedure for batch release of sterile injectable products after completion of manufacturing, quality control, and review of necessary documentation, ensuring product quality, safety, and compliance with GMP regulations.

2. Scope

This SOP applies to all batches of sterile injectable products

manufactured at the facility that require batch release by the Quality Assurance department.

3. Responsibilities

  • QA Officer: Review batch documentation and ensure all test results are within specifications.
  • QC Analyst: Provide validated analytical results for each batch.
  • Production Supervisor: Ensure BMR and logbooks are completed and submitted to QA.
  • Head QA: Final authority for batch release.

4. Accountability

The Head of Quality Assurance is accountable for the release of batches only after full compliance with product and process quality requirements.

5. Procedure

5.1 Batch Review and Approval

  1. Receive complete Batch Manufacturing Record (BMR) and batch packing records from production.
  2. QA performs a checklist-based review (Annexure-1) of BMR, ensuring ALCOA+ compliance.
  3. QC submits Certificates of Analysis (CoA) with results for all in-process and finished product tests.
  4. Compare actual yield with theoretical yield; acceptable deviation: ±5%.
  5. Ensure environmental monitoring, sterilization logs, and cleaning validation records are reviewed.

5.2 Final QA Review and Authorization

  1. Summarize findings in the Batch Release Authorization Form (Annexure-2).
  2. Confirm reconciliation of raw materials, packaging materials, and labels.
  3. Check compliance with all in-process control parameters.

5.3 Product Status Labeling

  1. Upon approval, affix “Released” status labels on shipper boxes.
  2. If rejected, move product to designated rejection area with red labels marked “REJECTED”.

5.4 Document Retention

  1. Store all batch records, CoAs, deviations, and release documents in the QA archive for a minimum of 5 years.
