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 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]
