Definition

A drug used to treat early puberty in males and females. Supprelin LA keeps the testicles and ovaries from making sex hormones by blocking other hormones that are needed to make them. This causes the testicles to stop making testosterone in males, and the ovaries to stop making estradiol (a form of the hormone estrogen) in females. Supprelin LA 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.
