PTCB Certified Pharmacy Technician (PTCE)Order Entry and ProcessingMedium
A pharmacy technician is preparing to process a prescription for a compounded sterile product. Which of the following is the PRIMARY purpose of aseptic technique in sterile compounding?
- ATo prevent microbial contamination of the final product.
- BTo control the pH balance of the compounded solution.
- CTo maintain the stability of heat-sensitive ingredients.
- DTo ensure the product is free of particulate matter.
Show answer & explanationAnswer & explanation
Correct answer: A. To prevent microbial contamination of the final product.
Aseptic technique is a set of practices performed under carefully controlled conditions to prevent contamination by microorganisms. In sterile compounding, its primary goal is to ensure the final product is free of bacteria, viruses, fungi, and other pathogens that could cause infection.
Why the other options are wrong
- B. Incorrect. Controlling pH is a formulation consideration for drug stability and patient comfort, not the primary purpose of aseptic technique.
- C. Incorrect. Maintaining stability of heat-sensitive ingredients is related to compounding process and storage, not the primary purpose of aseptic technique itself.
- D. Incorrect. While aseptic technique contributes to minimizing particulate matter, the primary focus is microbial contamination.
Aseptic Technique in Sterile Compounding
A set of practices used in sterile compounding to minimize or eliminate the introduction of microorganisms from the environment, personnel, or equipment into sterile preparations.
- Primary goal: Prevent microbial contamination.
- Involves hand hygiene, garbing, use of sterile equipment, and working in sterile environments (e.g., LAFW, BSC).
- Critical for patient safety, especially for IV drugs, ophthalmic solutions, and injectables.
- Governed by USP <797> standards.
Memory trick: Asepsis: No microbes in the IV.
