PTCB Certified Pharmacy Technician (PTCE)Patient Safety and Quality AssuranceMedium
A pharmacy technician is tasked with stocking medications in the pharmacy's refrigerator. Which of the following temperature ranges is considered appropriate for refrigerated medications, according to USP <797> guidelines?
- A0°C to 2°C (32°F to 35.6°F)
- B8°C to 15°C (46°F to 59°F)
- C15°C to 25°C (59°F to 77°F)
- D2°C to 8°C (36°F to 46°F)
Show answer & explanationAnswer & explanation
Correct answer: D. 2°C to 8°C (36°F to 46°F)
Maintaining medications within their specified temperature ranges is crucial for ensuring their stability, efficacy, and safety. Temperatures outside the recommended range can lead to drug degradation, loss of potency, or even toxicity.
Why the other options are wrong
- A. This range is too cold and risks freezing, which can damage many medications.
- B. This range is too warm for refrigerated medications and falls into the 'cool' or 'room temperature' category for some products, but not refrigeration.
- C. This range is considered controlled room temperature, not refrigeration.
Refrigerated Medication Storage
Refers to storing medications at a controlled temperature range between 2°C and 8°C (36°F and 46°F) to maintain their stability and efficacy, as per regulatory guidelines like USP <797>.
- Essential for temperature-sensitive drugs (e.g., insulin, vaccines).
- Prevents degradation and loss of potency.
- Requires regular temperature monitoring and documentation.
Memory trick: Cold meds need a 'Two-Eight' degree fate.
