Trimegestone (INN) (brand name Ondeva), also known as 21-hydroxypromegestone, as well as 17β-((S)-2-hydroxypropanoyl)-17α-methylestra-4,9-dien-3-one, is a steroidal progestin of the 19-norprogesterone group related to promegestone which was introduced in France in 2001 and is used as a hormonal contraceptive and in hormonal replacement therapy for postmenopausal symptoms.[1][2][3][4] It is not available in the United States.[5]
Trimegestone has very high affinity for the progesterone receptor, only weak affinity for the mineralocorticoid receptor, and little or no affinity for other steroid hormone receptors.[2][3][5] In accordance, it is described as a very potent and pure progestogen,[2] in fact the most potent progestin of the 19-norprogesterone group (clinically effective in endometriosis at only 0.1 mg/day),[2][3][6] and possesses weak antimineralocorticoid activity and no androgenic, antiandrogenic, estrogenic, or glucocorticoid activity.[6][7] Due to its unique structure, unlike progesterone and some other progestins, trimegestone does not metabolize into neuroactive steroids, and hence does not influence GABAA receptor signaling.[7]
