    Abarelix (R3827; PPI 149) is a potent gonadotrophin-releasing hormone (GnRH) antagonist, used for prostate cancer treatment.

    In Vitro

    Abarelix (30 and 300 µg/mL) causes significantly increased histamine release[1]. Abarelix is the first GnRH 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].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.
