Plenaxis (abarelix), a new drug for advanced prostate cancer
Some men will be asking about Plenaxis (abarelix), a new drug for advanced prostate cancer.
Plenaxis suppresses testosterone by blocking gonadotropin-releasing hormone receptors. It doesn't cause an initial testosterone surge...like Lupron and other gonadotropin agonists.
But Plenaxis has a serious drawback...it causes life-threatening allergic reactions in almost 4% of patients.
