  Buserelin (CAS NO.57982-77-1) may be used in the treatment of hormone-responsive cancers such as prostate cancer or breast cancer, estrogen-dependent conditions (such as endometriosis or uterine fibroids), and in assisted reproduction.

Human systemic effects by inhalation: blood pressure elevation. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NO_x.

  Buserelin , with CAS number of 57982-77-1, can be called (d-ser(bu(supt)(sup6)))-lh-rh(1-9)nonapeptide-ethylamide;(d-ser(tbu)(sup6)-ea(sup10))-lhrh;(d-ser(tbu)(sup6)-ea(sup10))-luteinizinghormone-releasinghormon ; d-ser(tbu(sup6))-lh-rh-(1-9)-nonapeptideethylamide ; d-ser-(tbu)(sup6)-lhrh-ethylamide ; (d-ser(tbu)(sup6)-ea(sup10))-luteinizinghormone-releasinghormone ; etilamide . Buserelin (CAS NO.57982-77-1) is normally delivered via a nasal spray but is also available as an injection. Buserelin acetate is marketed by Sanofi-Aventis under the brand name Suprefact and a generic form of Buserelin is now produced by CinnaGen under the brand name CinnaFact.
