Department Elixir Department
SOP No. SOP/ELX/087/2025
Supersedes SOP/ELX/087/2022
Page No. Page 1 of 8
Issue Date 11/04/2025
Effective Date 15/04/2025

1. Purpose

To define procedures and preventive measures to eliminate cross-contamination risks during the manufacturing of elixir products and to ensure compliance with GMP guidelines.

2. Scope

This SOP is applicable to all manufacturing activities within the Elixir Department where there is a risk of contamination due to shared equipment, personnel movement, air handling, and material transfers.

3. Responsibilities

  • Production Operator:
    • Follow defined gowning, cleaning, and equipment segregation procedures.
    • Report any potential contamination events immediately.
  • Production Supervisor:
    • Ensure proper scheduling and line clearance between batches.
    • Verify cleaning effectiveness and approve use of shared areas.
  • QA Officer:
    • Conduct environmental monitoring and audit adherence to contamination control practices.

4. Accountability

The Head of Production is accountable for implementation and periodic review of contamination control strategies and for ensuring corrective actions are implemented if risks are identified.

5. Procedure

5.1 Environmental and Facility Controls

  1. Manufacturing areas must be segregated by physical barriers, pressure differentials, or dedicated rooms where feasible.
  2. Maintain proper air filtration (HEPA filters) and HVAC zoning as per cleanroom classification.
  3. Perform cleaning of floors, walls, and surfaces after each batch or product changeover using validated disinfectants.

5.2 Personnel and Gowning

  1. Use dedicated cleanroom garments and accessories for each room.
  2. Follow gowning SOPs strictly and avoid personnel movement between manufacturing areas without gown change.
  3. Limit number of personnel in process areas as per defined occupancy limits.

5.3 Equipment Cleaning and Segregation

  1. Use dedicated or properly cleaned and sanitized equipment for each product.
  2. Perform line clearance and cleaning verification before initiating new batch processing.
  3. Use separate transfer lines and fittings where product nature demands (e.g., alcohol-based vs aqueous-based elixirs).

5.4 Material Handling

  1. Label all materials clearly with product name, batch number, and status (e.g., Approved, Quarantined).
  2. Transport materials in closed containers and along defined material movement routes.
  3. Do not store different product intermediates in the same tank or holding area.

5.5 Scheduling and Campaigning

  1. Where feasible, schedule manufacturing in campaigns of similar products to reduce changeovers.
  2. Avoid simultaneous processing of incompatible or high-risk products within the same room.

5.6 Deviation and Incident Handling

  1. Any suspected cross-contamination must be reported immediately to QA.
  2. Initiate deviation report and investigate with potential root cause analysis.
  3. Take corrective and preventive actions (CAPA) before restarting operations.
