At the onset of administration, nafarelin stimulates the release of the pituitary gonadotropins, LH and FSH, resulting in a temporary increase of gonadal steroidogenesis. Repeated dosing abolishes the stimulatory effect on the pituitary gland. Twice-daily administration leads to decreased secretion of gonadal steroids by about 4 weeks; consequently, tissues and functions that depend on gonadal steroids for their maintenance become quiescent. FDA-Approved Indication: Synarel is a GnRH agonist/nasal solution indicated for: Treatment of central precocious puberty (CPP) (gonadotropin-dependent precocious puberty) in children of both sexes; Management of endometriosis, including pain relief and reduction of endometriotic lesions.
