详细说明

DrugBank - DB01357

• Drug Groups: approved
• Description: The 3-methyl ether of ethinyl estradiol. It must be demethylated to be biologically active. It is used as the estrogen component of many combination ORAL contraceptives. [PubChem]
• Indication: Mestranol was used as one of the first oral contraceptives.

Research Area: Endocrinology
Biological Activity:
Mestranol is the 3-methyl ether of ethinylestradiol. It was the estrogen used in many of the first oral contraceptives. It is a biologically inactive prodrug of ethinylestradiol to which it is demethylated in the liver with a conversion efficiency of 70% (50 µg of mestranol is pharmacokinetically bioequivalent to 35 µg of ethinylestradiol).
