GnRH Agonist Analogs (Expanded)
Catalog grouping for clinically established GnRH agonist peptide drugs such as leuprolide, goserelin, triptorelin, and buserelin.
Overview
GnRH agonists are synthetic peptide analogs of gonadotropin-releasing hormone used as prescription drugs in oncology, gynecology, and assisted reproduction. The class includes leuprolide, goserelin, triptorelin, and buserelin. The suffix (Expanded) reflects a supplier catalog grouping rather than a scientific designation; the underlying class itself is well characterized and clinically established.
Mechanism
Physiologic GnRH is secreted in pulses that stimulate pituitary release of LH and FSH. Continuous exposure to a GnRH agonist desensitizes and downregulates the pituitary GnRH receptor, suppressing gonadotropin secretion and, after an initial stimulatory flare, gonadal sex-steroid production.
Dosing
These are prescription medicines with indication-specific regimens delivered as injectable depots, implants, or nasal sprays. Any research use outside approved indications should follow published protocols; supplier listings are not a valid dosing source.
Expected Effects
- reversible suppression of gonadal steroid production after the initial flare period
- reduction of estrogen-dependent lesion growth (endometriosis, uterine fibroids)
- prevention of premature LH surges in controlled ovarian stimulation cycles
- pituitary-gonadal axis suppression used in central precocious puberty
Side Effects & Tolerability
The side-effect profile reflects induced hypogonadism and includes hot flashes, mood changes, and bone-mineral-density loss with prolonged use, along with injection-site or implantation-site reactions. These effects are well documented from decades of clinical use.
Storage
Storage follows the manufacturer label of each pharmaceutical formulation; depot injectables and implants generally require controlled temperature and protection from light.
