Vantas
(VAN-tus)
A drug used as palliative therapy for advanced prostate cancer. Vantas keeps the testicles from making the male hormone testosterone by blocking other hormones that are needed to make it. This may slow or stop the growth of cancer cells that need testosterone to grow. Vantas contains the active ingredient histrelin acetate. It is a type of LHRH (or GnRH) agonist and a type of androgen deprivation therapy that is reversible.
