Summary
Prednisone given as part of abiraterone therapy with radium-223 was associated with more fractures and deaths. Corticosteroids themselves reduce bone density, so skeletal risk may be compounded.
What this interaction means in plain words
Prednisone and Radium ra-223 dichloride can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Prednisone belongs to Endocrine; Radium ra-223 dichloride belongs to Oncology.
Why it happens
The mechanism is not fully established; additive skeletal toxicity is suspected, including corticosteroid-induced bone loss.
What to do
Avoid using radium-223 with abiraterone plus prednisone outside trials; assess fracture risk and consider bone-protective therapy when steroids are required.
