Norethisterone Danazol

The synthesis of Lp(a) can be influenced by hormones, as is reported by Albers et al. (A7), who observed a reduction of Lp(a) concentrations in nor-molipidemic postmenopausal women treated during 6 weeks with the anabolic steroid stanazolol. The same effect was reported for norethisterone (FI) and danazol (Cl2). Exogenous estrogens, as used in treatment of postmenopausal complaints and in oral contraceptives, induce a decrease of Lp(a) (D9, H27, K13, KAO, L21, S37). This effect is dose-related and dependent on Lp(a) levels before treatment (F2). Watanabe (W9) investigated the influence of progestogen (alone) and detected a decrease of Lp(a) during treatment.
