What is the proper refrigeration temperature range for pharmaceuticals?

The proper refrigeration temperature range for pharmaceuticals is critical to ensure their stability and efficacy. The accepted range is between 36 to 46°F, which translates to 2 to 8°C. This range is established by guidelines from authoritative bodies such as the United States Pharmacopeia (USP) and the World Health Organization (WHO).

Maintaining this specific temperature range is essential for many medications that require refrigeration, such as certain vaccines, insulin, and biologics. If these medications are stored outside the recommended temperatures, it can result in reduced potency or even deterioration, potentially compromising patient safety.

The other options provide temperature ranges that fall outside the accepted guidelines. For instance, the range of 32 to 40°F does not adequately encompass the full range of stability for refrigerated pharmaceuticals, while the temperatures presented in the other choices, like 30 to 50°F and 40 to 50°F, exceed the recommended limits and put medications at risk of being improperly stored. This is why answer B is considered the correct response in this context.
