Compounding Procedures
Overview
Compounding is the process of preparing customized medications that are not commercially available, tailored to meet a patient’s individual needs. Within the Compounding Pharmacy Management System (PMS), compounding is tightly integrated with prescription data, inventory controls, and regulatory compliance to ensure accuracy, safety, and traceability.
1. Preparation & Formula Selection
System Features:
Formula database with pre-approved recipes, instructions, and beyond-use dates (BUDs)
Compatibility checks for dosage form (e.g., cream, capsule, suspension)
Links to required safety documents (SDS, USP guidelines)
User Actions:
Select the formula from the system or enter a new compound if approved by pharmacy leadership
Verify availability of active ingredients, excipients, and containers
Review any patient-specific modifications (flavoring, dosage adjustments, allergen avoidance)
2. Ingredient Verification
System Features:
Barcode scanning for lot numbers and expiration dates
Real-time inventory decrement when ingredients are assigned
Alerts if ingredient is expired, recalled, or insufficient
User Actions:
Match ingredient containers against PMS worksheet
Log initials and timestamp for chain-of-custody tracking
3. Compounding Execution
Technician Workflow:
Follow PMS-generated worksheet step by step
Record actual weights/volumes of each ingredient
Document equipment used (mortar, ointment mill, balance, capsule machine)
Capture environmental conditions when applicable (e.g., sterile cleanroom logs)
System Features:
Integration with scales for direct weight recording
Built-in calculations for scaling formulas (single vs. batch prep)
On-screen prompts for mixing order and techniques (levigation, trituration, geometric dilution, etc.)
4. Quality Control & Verification
Pharmacist Responsibilities:
Compare finished product to expected characteristics (appearance, consistency, volume)
Cross-check against PMS worksheet for ingredient accuracy and process compliance
Approve or reject compound before dispensing
System Features:
Digital QA checklist (ingredient verification, physical inspection, stability review)
Electronic sign-off with audit trail
Automatic lockout of dispensing until QA approval is complete
5. Documentation & Compliance
System Integration:
Automatically logs compounding event to prescription record
Tracks ingredient lots, expiration dates, and technician involvement for full traceability
Generates batch records for USP <795>, <797>, and <800> compliance
Supports recall management through backward ingredient traceability
6. Dispensing Readiness
System Actions:
Generates patient-specific labels (with auxiliary warnings, storage instructions)
Produces compounding log entry for regulatory reporting
Triggers inventory re-order thresholds if ingredients fall below par levels
Best Practices
Always perform double verification for active pharmaceutical ingredients (APIs)
Document exact measurements and avoid relying on approximations
Maintain separation of duties (technician compounds, pharmacist verifies)
Follow USP standards and state-specific compounding regulations at all times
