What is the controlled room temperature range according to standards?

The definition of controlled room temperature is established by various regulatory bodies and standards, including the United States Pharmacopeia (USP). According to these standards, controlled room temperature is defined as being within the range of 20°C to 25°C (68°F to 77°F). This temperature range is important for the storage of pharmaceuticals to ensure their stability and efficacy.

Maintaining medications within this range helps prevent degradation and ensures that the potency of drugs is preserved throughout their shelf life. While slight variations may be permissible under certain conditions, the standard 20°C to 25°C range is widely recognized and used in practice, making it the correct choice in this instance.
