The present disclosure provides compositions and methods for treating estrogen-dependent disorders, such as disorders of the female reproductive system, including uterine fibroids and endometriosis, among others. Compounds described herein that may be used to treat such indications include gonadotropin-releasing hormone (GnRH) antagonists. Suitable GnRH antagonists useful in conjunction with the compositions and methods described herein include thieno[3,4d]pyrimidine derivatives, such as 3-[2-fluoro-5-(2,3-difluoro-6-methoxybenzyloxy)4-methoxyphenyl]-2,4-dioxo-1,2,3,4-tetrahydrothieno [3,4d]pyrimidine-5-carboxylic acid and the choline salt thereof, among others. Using the compositions and methods described herein, GnRH antagonists may be periodically administered to a patient, such as one or more times per day, week, or month, in combination with periodic add-back therapy, thereby preventing bone mineral density loss that may otherwise accompany estrogen depletion effectuated by GnRH antagonist activity. Advantageously, using the dosing schedules of the present disclosure, the periodic administration the GnRH antagonist and add-back therapy may commence together, such as on the same day.
