Structurally, it is a decapeptide. It is the natural GnRH decapeptide with two substitutions to inhibit rapid degradation.
Goserelin stimulates the production of the sex hormones testosterone and estrogen in a non-pulsatile (non-physiological) manner. This causes the disruption of the endogenous hormonal feedback systems, resulting in the down-regulation of testosterone and estrogen production.
It was patented in 1976 and approved for medical use in 1987. It is on the World Health Organization's List of Essential Medicines.
