Structurally and functionally allyestrenol is similar to progesterone. For producing its action the drug binds to estrogen and progesterone receptor present in hypothalamus, pituitary and female reproductive tract. After binding to the target receptor it will slow the release of GnHR (gonadotropin releasing hormone) from hypothylamus. It causes the stimulation of mammary alveolar tissue and also causes relaxation of smooth muscle.
