Identification
Name Dydrogesterone
Accession Number DB00378 (APRD00941)
Type small molecule
Description A synthetic progestational hormone with no androgenic or estrogenic properties. Unlike many other progestational compounds, dydrogesterone produces no increase in temperature and does not inhibit ovulation. [PubChem]

Pharmacology
Indication Used to treat irregular duration of cycles and irregular occurrence and duration of periods caused by progesterone deficiency. Also used to prevent natural abortion in patients who have a history of habitual abortions.
Mechanism of action Dydrogesterone is a progestogen that works by regulating the healthy growth and normal shedding of the womb lining by acting on progesterone receptors in the uterus.
Absorption Rapidly absorbed in the gastrointestinal tract with a bioavailability of 28%.
Protein binding Not Available
Biotransformation Metabolism is complete to a 20-dihydrodydrogesterone (DHD) metabolite.
Route of elimination Not Available
Toxicity No serious or unexpected toxicity has been observed with dydrogesterone. In acute toxicity studies, the LD50 doses in rats exceeded 4,640mg/kg for the oral route.
Affected organisms
