 Abarelix Biological Activity

Description Abarelix is a potent gonadotrophin-releasing hormone (GnRH) antagonist, used for prostate cancer treatment.
Related Catalog
In Vitro Abarelix (30 and 300 µg/mL) and cetrorelix cause significantly increased histamine release[1]. Abarelix is the firstGnRH antagonist to be developed, and can produce rapid and sustained decreases in testosterone to castrate levels without the need for co-administration of an antiandrogen, and with a very low complication rate in the short term[2]. Abarelix demonstrates to promptly and substantially reduce follicle-stimulating hormone levels to lower than LHRH agonist. Abarelix does not cause a surge in serum testosterone that can precipitate a flare phenomenon or worsening of disease, particularly dangerous for patients with metastatic, symptomatic disease, and produces medical castration more quickly[3].
