Drug Distribution Systems: Institutional, Automation, Repackaging, Compounding, Sterile Products
Institutional pharmacy
Hospitals and other institutions hold a pharmacy permit, designate a pharmacist-in-charge, and operate under an approved formulary and a distribution system (unit dose, floor stock, or hybrid). Emergency kits and floor stock need locked control, documented checks, and pharmacist oversight.
Automated devices
Automated dispensing cabinets and pharmacy automation require written policies covering role-based access, user authentication, override criteria, restocking, reconciliation, and quality checks. Technicians may restock, but pharmacist verification and audit trails are essential; controlled substances in cabinets need perpetual inventory and discrepancy investigation.
Repackaging
Repackaging moves drug from a manufacturer's container into a smaller unit. The label carries drug name, strength, dosage form, lot or repackager control number, the expiration or beyond-use date assigned by the repackager, and storage conditions. Records link the new package to the original lot for recall traceability.
Compounding
Maryland expects compliance with USP 795 (nonsterile), 797 (sterile), and 800 (hazardous drugs). Core requirements:
- A master formulation record and a compounding record for each preparation.
- A beyond-use date justified by formulation, water content, preservative, and storage, not copied from the manufacturer's expiration date.
- Sterile compounding: an ISO-classified environment, primary engineering control, environmental monitoring, validated processes, trained and assessed personnel, and release checks.
Worked example
A hospital repackages oral tablets into unit-dose blisters. The repackager assigns a beyond-use date shorter than the manufacturer's expiration, labels each blister with its own control lot, and logs the link to the original manufacturer lot so a recall can be traced.
Traps
Assigning a BUD equal to the manufacturer's expiration; letting override reports go unreviewed; assuming a clean room satisfies USP 797 without monitoring and personnel qualification.
