What is defined as controlled room temperature for drug storage?

Controlled room temperature for drug storage is defined as the temperature range of 15 to 30 degrees Celsius. This definition is based on the standards set by regulatory agencies such as the U.S. Pharmacopeia (USP) and is essential for maintaining the stability and efficacy of pharmaceutical products.

Storing medications within this temperature range helps ensure that they remain safe and effective for use. It accounts for common fluctuations and variations in temperature that can occur in standard storage conditions while still allowing for optimal preservation of the drug's qualities. Understanding this temperature range is crucial for pharmacists and healthcare professionals to ensure compliance and uphold the integrity of medications throughout their shelf life.

Other ranges provided in the question do not conform to the established definitions for controlled room temperature, which is why they do not qualify.
