Prednisone is steroid and used sometimes with Ketoconazole, especially HDK (high dose keto useage).
The Tak-700 is like Abiraterone and it is like 10 times more power than Keto, they say. So now I see the why it was used, like doing HDK-Keto.
Since you went off of it the psa declined, how long does the Tak-700 stay in you, I assume is it capsule type useage? I have seen casodex feed PCa in some scenarios on hrpca type patients. On this one who knows, maybe doc can answer that one. If you take a drug and psa rises and you stop the drug and psa declines, I think any onco-doc would say drop the drug to obtain psa results.
Hey did you have any weird side effects on using these two combined drugs?
