Abarelix
GnRH antagonist for advanced prostate cancer. Depot formulation providing sustained testosterone suppression without initial flare, suitable for patients with metastatic disease.
Abarelix is a first-generation GnRH antagonist and a synthetic decapeptide used in the treatment of advanced prostate cancer, particularly castration-resistant (hormone-refractory) prostate cancer. It competitively blocks pituitary GnRH receptors, rapidly suppressing LH and FSH secretion to achieve rapid testosterone reduction to castrate levels, providing swift hormonal ablation therapy.
