Gestonorone acetate

Gestonorone acetate, or gestronol acetate, also known as norhydroxyprogesterone acetate, is a progestin of the 19-norprogesterone and 17α-hydroxyprogesterone groups which was developed in the early 1960s but was never marketed.[1][2][3][4][5][6][7][8][9][10][11][12][13][14] It is the C17α acetate ester of gestronol (17α-hydroxy-19-norprogesterone).

Gestonorone acetate has been found to consistently inhibit ovulation at an oral dosage of 10 mg/day in combination with 50 μg/day oral ethinylestradiol.[15] Weak or no endometrial effects were observed at an oral dosage of 100 mg/day, basal vacuoles appeared at 130 to 140 mg/day, and full endometrial secretory transformation occurred at 220 mg/day.[16]

Nach oraler Verabreichung von 100 mg des Hydroxy-nor-ProgesteronAcetats sah man nur schwache oder noch keine gestagene Wirkung am Endometrium (Abb. 3). Nach der oralen Dosis von 130- 140 mg traten basale Vacuolen auf, nach 220 mg war - außer bei einer Patientin mit individuell geringerer Ansprechbarkeit des Endometriums (2) - eine volle sekretorische Umwandlung erreicht: [...]
