Nizoral (ketoconazole, keto) is an older drug that has been used as a part of hormone therapy (ADT) for many years. Keto, which is an inexpensive anti-fungal drug had been used for many years as an inhibitor of adrenal androgen synthesis as is abiriterone (Zytiga). Ztiga has been shown to be more effective, however, it [...]
It has always been assumed that Ketoconazole, when used for the treatment of men with metastatic castration resistant prostate cancer (mCRPC), would not be as potent as abiraterone (Zytiga), but there has never been any head to head comparison to demonstrate this assumption! Ketoconazole is a less potent inhibitor of the CYP-17 enzyme, the mode [...]
Some men with advanced prostate cancer have been given the antifungal treatment Ketoconazole (Keto) as a second line hormone treatment. Like Keto, this newer hormone treatment that is now available, Abiraterone acetate (AA) (Zytiga) works by inhibiting CYP17, the rate-limiting enzyme in androgen biosynthesis. The question being asked, if Keto has failed ,given its similar [...]
Zytiga (abiraterone acetate) and Ketoconazole (keto) are both widely used in prostate cancer therapy to treat men with advanced prostate cancer. They both have a common mechanism of action, they both work by inhibiting the enzyme CYP17 that is responsible for androgen biosynthesis (creation). Inhibiting CYP17 lowers testosterone levels, which results in prostate cancer tumor regression. Because [...]
The use of Ketoconazole (Keto) in men with advanced prostate cancer is not considered mainstream, however there is clear evidence that it does reduce PSA in men with castrate resistant prostate cancer. Currently, most men with advanced prostate cancer who do use Keto utilize it prior to chemotherapy. There has been little literature evaluating the [...]
