Allowable room temperature excursions for refrigerated medications: A 20-year review

摘要

Purpose The aim of this review was to build upon previous literature describing the maximum duration for which refrigerated medications can tolerate room temperature excursions while maintaining stability and potency. Methods During a 12-month period ending in June 2021, the prescribing information and published monographs from multiple pharmacy compendia were reviewed for all medications and biologic products approved by the US Food and Drug Administration (FDA) for human use since January 2000. Products that were subsequently withdrawn from the US market were excluded. When temperature excursion data was unavailable in published form, product manufacturers were surveyed via telephone and/or email. Acceptable storage information for all products for which storage is recommended at temperatures below room temperature (20-25 degrees C 68-77 degrees F) was compiled and arranged in tabular format. Results Of the 705 products or formulations approved by FDA during the predefined time period, 246 were identified as requiring storage at temperatures below room temperature. After review of available prescribing information and manufacturer communications, if applicable, acceptable periods of excursion to temperatures at room temperature or higher were identified for 214 products (87). Conclusion Information related to acceptable periods of room temperature excursion was compiled for a total of 214 products approved for US distribution since 2000. The included tables may increase patient safety and decrease medication loss or related expenditures.
