| Description | Abarelix (PPI 149) is a potent gonadotrophin-releasing hormone (GnRH) antagonist, which is used for prostate cancer treatment. |
| In vitro | Abarelix, at concentrations of 30 and 300 µg/mL, significantly increases histamine release[1]. It rapidly and considerably lowers follicle-stimulating hormone levels below those achieved by LHRH agonists. As the inaugural GnRH antagonist developed, Abarelix achieves fast and sustained testosterone reductions to castrate levels without requiring concurrent antiandrogen therapy, exhibiting a remarkably low short-term complication rate[2]. Unlike other treatments, it avoids the testosterone surge that can exacerbate symptoms or disease progression, particularly in patients with metastatic, symptomatic conditions, facilitating quicker medical castration[3]. |
