Mechanism

Decapeptide GnRH agonist that initially stimulates then desensitizes pituitary GnRH receptors, suppressing LH, FSH, and downstream gonadal steroid production after the initial flare.

Research areas
  • Advanced prostate cancer
  • Central precocious puberty (international)
  • Endometriosis (international)
Considerations
  • FDA-approved.
