The Orthopedic Office Wants 100 Syringes
A community pharmacy with sterile compounding capability prepares a patient-specific prescription: cefazolin 2 g in 100 mL 0.9% sodium chloride for a home-infusion patient, compounded in an ISO Class 5 hood inside an ISO Class 7 buffer room, stored refrigerated, picked up in two days. That week a local orthopedic office asks the pharmacy to compound 100 prefilled syringes of "bupivacaine 0.25% with ketorolac 30 mg" for the surgeon to use on whatever patient needs one next month. Separately, a prescriber orders preservative-free gentamicin 0.3% ophthalmic solution, and the pharmacist plans a 100 mL batch with a 90-day beyond-use date at room temperature to avoid repeat compounding.
1. Can the pharmacy accept the orthopedic office's request for 100 prefilled syringes?
Read the worked answer
No. Decline and explain why.
- Compounding under the pharmacy exemption is patient-specific: a prescription for an identified patient, based on a prescriber-patient relationship. Producing 100 units of a sterile injectable for a prescriber to hold for unspecified future patients is manufacturing, which requires registration as an FDA outsourcing facility (503B) and compliance with cGMP.
- Office-use distribution of compounded sterile preparations is not something a community pharmacy can bootstrap by calling it "compounding." Any state-permitted office-use allowance is narrow and does not stretch to a large anticipatory batch of an injectable.
- The formula itself deserves scrutiny: intra-articular bupivacaine plus ketorolac is not a standard, well-documented combination, and chondrotoxicity concerns with local anesthetics exist. You would want literature support before compounding it for even one patient.
Refer the office to an FDA-registered 503B facility or to FDA-approved single-dose products, and document the refusal. If a specific patient has a prescription, you can evaluate that individual order on its merits.
2. The pharmacist assigns the compounded gentamicin ophthalmic solution a 90-day room-temperature beyond-use date. Is that defensible?
Read the worked answer
No - it is far outside any supportable BUD and is a patient-safety violation.
- An ophthalmic preparation must be sterile; a preservative-free aqueous solution in a multidose container carries a real risk of microbial contamination.
- The BUD for a compounded sterile preparation is set by USP <797> as adopted by the Board, based on the preparation category and storage temperature, and can be lengthened only with validated sterility testing and container-closure integrity data. Under current <797> categories, room-temperature BUDs for aseptically prepared CSPs are measured in hours to a few days - not 90 days.
- A 100 mL "batch" also implies production beyond one patient's need; compound a patient-appropriate quantity with a master formulation record, lot numbers, and an assigned BUD consistent with the category.
Practical answer: compound a small volume, assign the correct category BUD, label with the exact beyond-use date and time, store per the category, and counsel the patient to discard at the BUD.
3. The next morning the refrigerator data logger shows 12 degrees C for 8 hours overnight. The cefazolin bag is due for pickup that afternoon. What now?
Read the worked answer
Quarantine, assess, document - then decide. Do not silently re-date.
- Segregate the bag with a "DO NOT DISPENSE - temperature excursion" tag and keep it out of the pickup area.
- A documented excursion outside the validated 2–8 degrees C range invalidates the assigned BUD unless you can support the new storage history with stability data. Pull the cefazolin-in-sodium-chloride stability references (or call the manufacturer) and see whether 8 hours at 12 degrees C falls within documented stability. Cefazolin is comparatively stable, so the answer may be that the product is still acceptable - but that is a documented conclusion, not an assumption.
- Notify the prescriber and patient of the delay; re-prepare if the assessment is unfavorable or the data are ambiguous. Record the excursion dates and times, the data-logger output, the stability reference relied on, and who made the decision.
- Fix the root cause: the excursion happened once and will happen again unless the refrigerator is alarmed and monitored.
