What is the standard freezer temperature range for pharmaceutical storage?

• A. -80 to -60 C
• B. -20 to -26 C (-4 to -14 F)
• C. 2 to 8 C
• D. -40 to -20 C

Answer: (B)

Maintaining medicines at a temperature well below 0 C slows chemical reactions and prevents degradation and microbial growth. The standard freezer range used in pharmaceutical storage is -20 to -26 C (-4 to -14 F). This range is cold enough to preserve the stability of many temperature-sensitive drugs and biologics, while staying within what most standard pharmaceutical freezers can reliably maintain. It’s colder than the typical refrigerator (2 to 8 C), which is intended for non-freezing storage, and not as cold as ultra-low freezers or deep freezers that are reserved for products requiring extreme cold or long-term storage. In short, this range represents a practical, widely used standard for freezing medications that need to be kept below freezing but not at ultra-low temperatures.
