1 Novel GnRH antagonists, such as degarelix, and cytochrome P450 17 (CYP17) enzyme inhibitors, such as ketoconazole, achieve castrate-equivalent serum testosterone levels much faster than traditional GnRH agonists without the need for coadministration of antiandrogens. Ketoconazole cytochrome P450 family 17 subfamily A member 1 Homo sapiens

3 In the setting of symptomatic hormone-naive metastatic prostate cancer, the authors suggest clinical trials using abiraterone, orteronel, and other newer agents that target the CYP17 axis (eg, ketoconazole) for fine-tuning the emergent medical castration methods and avoiding the dangers from the flare phenomenon.
