Estradiol/norethisterone (E2/NET), tentative brand name Netagen or Netagen 403, was a combination of estradiol (E2), an estrogen, and norethisterone (NET), a progestin, which was studied as a birth control pill to prevent pregnancy in women.[1][2][3][4][5] It was taken by mouth and contained 4 mg micronized E2 and 3 mg NET per tablet.[2][3] The medication was developed by Novo Pharmaceuticals in Denmark and was never marketed.[1][2][3]

Two related formulations were Netagen 423 (4 mg estradiol, 2 mg estriol, 3 mg norethisterone) and Netasyn (50 μg ethinylestradiol, 3 mg norethisterone), were also studied but never marketed.[1][3][4]
