In this study, the effects of chlormadinon acetate (CMA) and CMA + nordihydroguaiaretic acid (NDGA) on various developmental stages of Drosophila melanogaster were investigated. Different concentrations of CMA (1.0; 3.0; 5.0 and 10.0 μM/100 mL medium) and CMA + NDGA

Contraception, 82(2), 131-138 (2010-07-27)
Chlormadinone acetate (CMA) is a progestin compound similar to progesterone, with antiandrogenic properties. In healthy eumenorrheic women, it was demonstrated that the monophasic estroprogestin formulation containing CMA (2 mg) plus ethinyl estradiol (EE) (30 mcg) (EE30+CMA) is efficacious both in
