22 Maintaining Quality and Safety of the Compounded Preparation
To ensure the quality and safety of compounded non-sterile preparations, pharmacies must adhere to a structured framework outlined in NAPRA’s Model Standards and Guidance Document. Many of these things have already been discussed in more detail.
1. Risk Assessment and Mitigation
- Conduct a risk assessment for every preparation to evaluate:
- Product risks: Contamination (microbial, chemical, physical), stability, and formulation complexity.
- Personnel risks: Exposure to hazardous ingredients (e.g., cytotoxic drugs, allergens).
- Assign a risk level (A, B, or C) using NAPRA’s decision algorithm, which dictates facility, equipment, and procedural requirements.
- Document mitigation strategies, such as engineering controls (e.g., ventilation), PPE, and workflow adjustments.
2. Personnel Competency and Training
- Initial and ongoing training: Ensure all compounding personnel complete training on SOPs, equipment use, and safety protocols.
- Competency assessments: Validate skills annually or when procedures change (e.g., capsule filling, hazardous drug handling).
- Designate a compounding supervisor (pharmacist or qualified technician) to oversee compliance and training.
3. Facility and Environmental Controls
- Level-specific requirements:
- Level A: Designated clean area, separate from high-traffic zones.
- Level B: Enclosed room with smooth, cleanable surfaces; potential ventilation upgrades.
- Level C: Negative-pressure room with containment devices (e.g., ventilated hoods) for hazardous drugs.
- Cleaning and maintenance:
- Daily cleaning logs for surfaces and equipment.
- Regular calibration of balances, pH meters, and other tools.
4. Documentation and Formulation Integrity
- Master Formulation Records (MFRs):
- Include evidence-based recipes, stability data, BUD rationale, and safety precautions
- Update MFRs when formulations or procedures change
- Compounding records:
- Document each batch, including ingredient verification, weights, and personnel involved
- Environmental and equipment monitoring
- Corrective actions taken for deviations or quality issues
5. Ingredient Verification and Handling
- Verify ingredients:
- Check identity, purity, and expiry dates before use.
- Hazardous ingredients:
- Use Safety Data Sheets (SDS), NIOSH lists, and WHMIS classifications to determine handling requirements (e.g., PPE, containment).
6. In-Process and Final Product Checks
- In-process verification:
- Double-check calculations and measurements.
- Use calibrated equipment for weighing and mixing.
- Final product inspection:
- Physical checks for uniformity, color, and absence of contaminants.
- Label accuracy (active ingredients, BUD, storage conditions).
7. Stability and Beyond-Use Dating (BUD)
- Assign BUDs using:
- Published stability data (preferred).
- Default NAPRA timelines (e.g., 30 days for water-containing topical preparations).
- Never exceed the shortest expiry date of any ingredient.
8. Environmental Monitoring and Cleaning
- Routine surface testing:
- Swab compounding areas to detect microbial contamination.
- Waste disposal:
- Segregate hazardous waste (e.g., cytotoxic residues) and use leak-proof containers.
9. Incident Management and Continuous Improvement
- Report deviations: Document errors, contamination events, or equipment failures.
- Corrective actions: Investigate root causes and update SOPs to prevent recurrence .
- QA audits:
- Conduct regular audits using checklists to assess compliance with NAPRA standards
10. Transportation Considerations
If a compounded preparation is to be delivered or transported:
- Package securely to prevent leakage, breakage, or exposure to adverse conditions
- Use temperature-control measures when necessary (e.g., cold packs, insulated containers)
- Label outer packaging clearly with any necessary handling or storage instructions
- A tracking system should be in place to monitor delivery timelines and ensure timely receipt by the patient or caregiver.
11. Patient Understanding and Compliance
- The pharmacist must ensure the patient knows how to use and store the medication properly
- Counselling must occur for every new prescription to go over things like how to use, store and dispose the compounded preparation.
12.Batch Recall Procedures
- Lot numbers should be documented and have a system for product recalls
- Patients need to be contacted if a compounded batch is found to be compromised.
13. Standard Operating Procedures (SOPs)
- There must be SOPs or all critical steps in the compounding process
14. Label Template Standardization
- Using standardized labeling templates (with required warnings, BUD, storage instructions) help reduce errors and meet compliance requirements
Ensuring the safety and quality of non-sterile compounded preparations requires more than just adherence to technical protocols—it requires a culture of accountability, precision, and continuous improvement. This chapter has highlighted the essential systems that support safe compounding: risk assessment, training, environmental control, documentation, verification, and patient counselling. Ultimately, quality and safety are not the responsibility of a single individual but the collective responsibility of the entire compounding team. By maintaining well-documented processes, proactively managing risks, and continuously evaluating outcomes through quality assurance measures, pharmacies can confidently deliver safe, effective, and personalized therapies to patients.
