GnRH analogues.S gonadorelin role with cloth.Repeat given large doses of luteinizing generated releasing hormone (LH - RH) or its highly active derivatives light c gonadorelin acetate, immediately after the first dose to produce a pituitary gonad system of sexual excitation (acute), and then inhibit pituitary gonadotropins to generate and release.It also further inhibit ovarian and testicular reactions to gonadotropin, thereby reducing the generation of estradiol and t(chronic).Light c gonadorelin acetate luteinizing hormone (LH) generated release activity about LH - 100 times of RH, its inhibition of pituitary gonad function is stronger than the effect of LH - RH.

Light c gonadorelin acetate is highly active LH - RH derivatives, due to its resistance to protein decomposing enzyme and affinity for the LH and RH receptors are stronger than LH and RH, so can effectively restrain the function of the pituitary gonad system.

Functions
