Norgestrienone, sold under the brand names Ogyline, Planor, and Miniplanor, is a progestin medication which has been used in birth control pills, sometimes in combination with ethinylestradiol.[1][2][3][4][5] It was developed by Roussel Uclaf and has been registered for use only in France.[4][5][6] Under the brand name Planor, it has been marketed in France as 2 mg norgestrienone and 50 μg ethinylestradiol tablets.[7] It is taken by mouth.[5]

Norgestrienone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[8] It has some androgenic activity.[9][10][11][12]

Norgestrienone was first described in the literature in 1965.[10] It is sometimes referred to as a "second-generation" progestin.[13] Norgestrienone is no longer available.[citation needed]

Norgestrienone is a progestogen structurally related to norethisterone that has been used as an oral contraceptive. Typical doses have been 2 mg daily with an oestrogen, and 350 micrograms daily when used alone.
