Metabolite Identification
Common Name Danazol
Description Danazol is a synthetic steroid with anti-oestrogenic and anti progestogenic activity, and weak androgenic properties. Danazol suppresses oestrogen and progesterone receptors in the endometrium, leading to endometrial atrophy (thinning of the lining of the uterus) and reduced menstrual loss and to amenorrhoea in some women. Danazol significantly lowers the duration of menses when compared with NSAIDs and a progesterone releasing IUD; however, caused more adverse events than NSAIDs and progestogens. The use of Danazol may be limited by its side effect profile, its acceptability to women and the need for continuing treatment. Because danazol is structurally related to the anabolic steroid stanozolol, its use should be questioned. Derivatization methods and GC/MS data are used to implement danazol detection in routine screening and confirmation procedures in doping analysis. Danazol main metabolite ethisterone is excreted relatively fast in urine. (PMID: 17636649 Link_out, 1640693 Link_out, 16288903 Link_out).
