Methallenestril (INN Tooltip International Nonproprietary Name ) (brand names Cur-men , Ercostrol , Geklimon , Novestrine , Vallestril ), also known as methallenoestril (BAN Tooltip British Approved Name ) and as methallenestrol , as well as Horeau's acid ,[ 1] [ 2] is a synthetic nonsteroidal estrogen and a derivative of allenolic acid and allenestrol (specifically, a methyl ether of it) that was formerly used to treat menstrual issues but is now no longer marketed.[ 3] [ 4] [ 5] [ 6] It is a seco-analogue of bisdehydrodoisynolic acid , and although methallenestril is potently estrogenic in rats, in humans it is only weakly so in comparison.[ 7] Vallestril was a brand of methallenestril issued by G. D. Searle & Company in the 1950s.[ 8] Methallenestril is taken by mouth .[ 9] By the oral route, a dose of 25 mg methallenestril is approximately equivalent to 1 mg diethylstilbestrol , 4 mg dienestrol , 20 mg hexestrol , 25 mg estrone , 2.5 mg conjugated estrogens , and 0.05 mg ethinylestradiol .[ 9]
