menopausal symptoms.[1] It is taken by mouth, in through the vagina, and by injection.[1][4][5] Medical usesEstriol succinate is used in menopausal hormone therapy in the treatment and prevention of menopausal symptoms such as hot flashes, vaginal atrophy, and osteoporosis.[1] Unlike other estrogens, depending on how it is used (i.e., how often it is taken and at what dosage), estriol succinate may not require concomitant therapy with a progestogen to prevent endometrial hyperplasia and endometrial cancer in women with intact uteruses.[1] Available formsEstriol succinate is and has been available in the form of 2 and 4 mg oral tablets, as a 0.1% vaginal cream, and as a 20 mg vial for use by injection.[2][3] Side effects{{See also|Estriol (medication)#Side effects}}Pharmacology{{See also|Estriol (medication)#Pharmacology}}Estriol succinate is an estrogen ester, specifically, an ester of estriol, and acts as a prodrug of estriol in the body.[10][1] It is described as a weak estrogen in comparison to estradiol valerate.[1][4] Estriol succinate is used medically via oral and vaginal routes similarly to estriol.[1] In estriol succinate, two of the hydroxyl groups of estriol, those at the C16α and C17β positions, are esterified with succinic acid.[1] As such, a dose of 2 mg estriol succinate is equivalent to 1.18 mg unconjugated estriol.[1] Unlike other estrogen esters, such as estradiol valerate, estriol succinate is nearly not hydrolyzed in the intestinal mucosa, and in relation to this, is absorbed more slowly than is estriol.[1] Instead of in the gastrointestinal tract, estriol succinate is cleaved into estriol mainly in the liver.[1] After a single 8 mg oral dose of estriol succinate, maximum levels of circulating estriol of 40 pg/mL are attained within 12 hours, and this increases up to 80 pg/mL with continued daily administration.[1] {{Oral potencies of estrogens}}Chemistry{{See also|List of estrogen esters#Estriol esters}}Estriol succinate, also known as estriol disuccinate or as estriol 16α,17β-di(hydrogen succinate), is a synthetic estrane steroid and a derivative of estriol.[10][21][22] It is specifically the C16α and C17β disuccinate ester of estriol.[10][21][22][1] The medication is provided both as estriol succinate and as estriol sodium succinate, the sodium salt.[10][21] Other marketed estriol esters besides estriol succinate include estriol acetate benzoate and estriol tripropionate, whereas estriol dihexanoate, estriol dipropionate, and estriol triacetate are estriol esters that were never marketed.[10][21] Quinestradol is an estriol ether and has also been marketed.[10][21] Polyestriol phosphate is an ester of estriol in the form of a polymer, and was previously marketed.[5][6][7][8] HistoryEstriol succinate was introduced for medical use in 1966.[37] Society and cultureGeneric namesEstriol succinate is the generic name of the drug and its {{abbrlink|INN|International Nonproprietary Name}} and {{abbrlink|BAN|British Approved Name}}.[9][10][11][12][13] Other synonyms include oestriol succinate, estriol disuccinate, and estriol hemisuccinate.[9][10][11][12] When provided as the sodium salt, estriol succinate is known as estriol sodium succinate ({{abbrlink|BAN|British Approved Name}}) or as oestriol sodium succinate.[9][10]Brand namesEstriol succinate has been marketed under brand names including Blissel, Evalon, Gelistrol, Hemostyptanon, Orgastyptin, Ovestin, Sinapause, Styptanon, Synapsa, Synapasa, Synapausa, and Synapause, among others.[9][10][11][12] Estriol sodium succinate has been marketed specifically under the brand names Pausan and Styptanon.[9][10] AvailabilityEstriol succinate is or has been marketed in Europe, Hong Kong, and Mexico.[10][12] ResearchEstriol succinate was under development for the treatment of multiple sclerosis in the United States and worldwide, and reached phase II clinical trials for this indication, but development was discontinued due to insufficient effectiveness.[14] It had the tentative brand name Trimesta.[14] References1. ^1 2 3 4 5 6 7 8 9 10 11 12 13 {{cite journal | vauthors

Phosphoric acid combines with the estrogen molecule at C3 and C17 to form a macromolecule. The compound is stored in the liver and spleen where the estrogen is steadily released by splitting off of the phosphate portion due to the action of alkaline phosphatase. [...] Conjugated estrogens and polyestriol and estradiol phosphate can also be given intravenously in an aqueous solution. Intravenous administration of ovarian hormones offers no advantages, however, and therefore has no practical significance. [...] The following duarations of action have been obtained with a single administration (WlED, 1954; LAURITZEN, 1968): [...] 50 mg polyestradiol phosphate ~ 1 month; 50 mg polyestriol phosphate ~ 1 month; 80 mg polyestriol phosphate ~ 2 months.}} 8. ^{{cite book|author=S.
