Use cyclodextrins as a radiostabilizer
Using CDs to stabilize drugs chemically is rather frequently used. But did you know that they can also be used to stabilize radiopharmaceuticals? According to the patent of GE HealthCare (Kristine Opsvik Wikene; Kahn Imtiaz Ahmed; Graeme McRobbie) combined with a radiostabilizer (like ascorbic acid), a cyclodextrin as co-stabilizer improves the stability of radiopharmaceuticals compared to using a conventional stabilizer.
