Description
Ganirelix is a GnRH antagonist used in assisted reproduction in women undergoing controlled ovarian hyperstimulation to control ovulation by inhibiting the premature LH surges.
Pharmacodynamics
Ganirelix is an injectable competitive gonadotropin-releasing hormone antagonist (GnRH antagonist). It is utilized frequently in assisted reproduction therapy to control the occurrence of ovulation. The drug exerts its effects by inhibiting the action of GnRH in the pituitary gland, leading to fast suppression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Ganirelix is used in fertility treatment to prevent premature ovulation that could result in the harvesting of eggs that are too immature to be used in procedures such as in vitro fertilization.
