🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by delivering progesterone, which binds to progesterone receptors in the nucleus of target cells. This binding activates gene transcription and produces effects that prepare the endometrium for implantation, maintain pregnancy, and regulate the menstrual cycle. It also suppresses the release of gonadotropin-releasing hormone, which can prevent ovulation in certain situations.
