What is the Origin of Goserelin?

Goserelin belongs to the class of GnRH agonists, which were developed to exploit the physiological mechanism of GnRH regulation for therapeutic benefit. The drug's peptide structure is a modified version of the endogenous hypothalamic GnRH, allowing for enhanced stability and receptor affinity. Its clinical utility stems from the pharmacological strategy of inducing a state of desensitization in the pituitary gland.

What is the Mechanism of Goserelin?

Upon initial administration, Goserelin causes a transient surge in Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), leading to a temporary increase in sex hormone levels, known as a flare effect. However, continuous exposure to the high concentration of the GnRH analog rapidly downregulates and desensitizes the GnRH receptors on the pituitary gonadotroph cells. This desensitization effectively halts the pulsatile release of LH and FSH, leading to a sustained suppression of gonadal steroidogenesis and a subsequent clinical reduction in circulating testosterone or estrogen levels.

Meaning

A synthetic decapeptide analog of Gonadotropin-Releasing Hormone (GnRH) that functions as a potent hormonal agent used clinically in the management of hormone-sensitive cancers, such as prostate and breast cancer, and in certain benign gynecological conditions like endometriosis. Administered as a subcutaneous implant, it provides a continuous, sustained release of the drug, leading to a profound suppression of sex hormone production. It is a form of medical castration.
