Use of ethinylestradiol and drospirenone for the preparation of a medicament for the treatment of post-traumatic stress disorder
PendingCN122351259ADrospirenoneOral contraceptive drug
This invention discloses the application of ethinylestradiol and drospirenone in the preparation of drugs for treating post-traumatic stress disorder (PTSD). Ethinylestradiol, as an estrogen receptor agonist, regulates the hypothalamic-pituitary-gonadal axis and is used to treat female hypogonadism, menopausal syndrome, and advanced breast cancer, often in combination with progestins as oral contraceptives. The use of drospirenone and ethinylestradiol tablets (II) after induced abortion can shorten vaginal bleeding time, promote endometrial repair, and reduce the incidence of postoperative complications and repeat miscarriages. This invention has found that ethinylestradiol and drospirenone can reverse the abnormal decrease in hormones and neurosteroids caused by PTSD after spontaneous abortion, particularly the abnormal decrease in serotonin and tetrahydroprogesterone.
