🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to progesterone receptors in target tissues such as the endometrium, myometrium, and hypothalamus. By mimicking the action of natural progesterone, it transforms the proliferative endometrium into a secretory state, which helps regulate bleeding and reduce endometrial thickness. It also suppresses gonadotropin release, leading to reduced ovarian stimulation and decreased estrogen production. This results in a variety of therapeutic effects, including control of abnormal uterine bleeding and reduction of endometriotic lesions.
