Allyestrenol is a synthetic progestogen used mainly in pregnancy support. It helps maintain appropriate progesterone activity required for fetal development and pregnancy sustainability. It is widely used in obstetrics and gynecology for preventing miscarriage, managing threatened abortion, habitual miscarriage, and certain pre-term labor risks. With good global demand, particularly in developing markets, Allyestrenol is supplied as a high-purity API for tablet formulations.
Allyestrenol is a synthetic progestogen that mimics the action of natural progesterone. It binds to progesterone receptors in the uterus, helping maintain a supportive environment for pregnancy. By stabilizing the endometrium, it reduces uterine contractions and prevents premature labor.
