They are modeled after the hypothalamic neurohormone GnRH, which interacts with the GnRH receptor to elicit its biologic response, the release of the pituitary hormones follicle-stimulating hormone FSH and luteinizing hormone LH.

From Wikipedia, the free encyclopedia. GnRH agonists are synthetically modeled after the natural GnRH decapeptide with specific modifications, usually double and single substitutions and typically in position 6 amino acid substitution9 alkylation and 10 deletion.

Brook’s Clinical Pediatric Endocrinology. Initial administration of LHRH agonists reliably causes a transient rise in serum T, with peak T values observed at 2—4 d followed by a reduction to baseline values by 7—8 d, and achievement of castrate levels by 2—4 wk [10].

Despite this however, they continue to be very expensive. GnRH agonists that have been marketed and are available for medical use include buserelingonadorelingoserelinhistrelinleuprorelinnafarelinand triptorelin. These drugs can be both peptides and small-molecules. Side effects of the GnRH agonists are signs and symptoms of hypoestrogenismincluding hot flashesheadaches, and osteoporosis.

The clinically used desensitizing GnRH agonists are available in the following pharmaceutical formulations: Generally, long-term patients, both male and female, tend to undergo annual DEXA scans to appraise bone density. Chemical structures of GnRH agonists. Sex steroid antagonists via disinhibition of the HPG axis: Side effects of GnRH agonists are related to sex hormone deficiency and include symptoms of low testosterone levels and low estrogen levels such as hot flashessexual dysfunctionvaginal atrophyosteoporosisinfertilityand diminished sex-specific physical characteristics.


Injectables have been formulated for daily, monthly, and quarterly use, and implants are available that can last from one month to a year. How serious is it?

Women of reproductive age who undergo cytotoxic chemotherapy have been pretreated with GnRH agonists to reduce the risk of oocyte loss during such therapy and preserve ovarian function.
