EthamoxytriphetolEthamoxytriphetol (developmental code name MER-25) is a synthetic nonsteroidal antiestrogen that was studied clinically in the late 1950s and early 1960s but was never marketed. MER-25 was first reported in 1958, and was the first antiestrogen to be discovered. It has been described as "essentially devoid of estrogenic activity" and as having "very low estrogenic activity in all species tested".
Ethinylestradiol sulfonateEthinylestradiol sulfonate (EES), sold under the brand names Deposiston and Turisteron among others, is an estrogen medication which has been used in birth control pills for women and in the treatment of prostate cancer in men. It has also been investigated in the treatment of breast cancer in women. The medication was combined with norethisterone acetate in birth control pills. EES is taken by mouth once per week. Side effects of EES in men include breast tenderness, gynecomastia, feminization, sexual dysfunction, and cardiovascular complications, among others.
Steroid esterA steroid ester is an ester of a steroid. They include androgen esters, estrogen esters, progestogen esters, and corticosteroid esters. Steroid esters may be naturally occurring/endogenous like DHEA sulfate or synthetic like estradiol valerate. Esterification is useful because it is often able to render the parent steroid into a prodrug of itself with altered chemical properties such as improved metabolic stability, water solubility, and/or lipophilicity.
Estradiol-containing birth control pillCombined birth control pills that contain natural estradiol or an estradiol ester (e.g., estradiol valerate) include: Estradiol valerate and cyproterone acetate (brand name Femilar) – introduced in Finland (only) in 1993 Estradiol valerate and dienogest (brand names Qlaira, Natazia) – introduced in Europe in 2009 and the () in 2010 Estradiol and nomegestrol acetate (brand name Zoely) – introduced in Europe in 2011 Estradiol, mainly as esters including estradiol valerate, estradiol cypionate, and estradiol enanthate, is also the exclusive estrogen used in combined injectable contraceptives.
Estrogen (medication)An estrogen (E) is a type of medication which is used most commonly in hormonal birth control and menopausal hormone therapy, and as part of feminizing hormone therapy for transgender women. They can also be used in the treatment of hormone-sensitive cancers like breast cancer and prostate cancer and for various other indications. Estrogens are used alone or in combination with progestogens. They are available in a wide variety of formulations and for use by many different routes of administration.
NorgestrienoneNorgestrienone, sold under the brand names Ogyline, Planor, and Miniplanor, is a progestin medication which has been used in birth control pills, sometimes in combination with ethinylestradiol. It was developed by Roussel Uclaf and has been registered for use only in France. Under the brand name Planor, it has been marketed in France as 2 mg norgestrienone and 50 μg ethinylestradiol tablets. It is taken by mouth. Norgestrienone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.
MammoplasiaMammoplasia is the normal or spontaneous enlargement of human breasts. Mammoplasia occurs normally during puberty and pregnancy in women, as well as during certain periods of the menstrual cycle. When it occurs in males, it is called gynecomastia and is considered to be pathological. When it occurs in females and is extremely excessive, it is called macromastia (also known as gigantomastia or breast hypertrophy) and is similarly considered to be pathological.
Estradiol benzoateEstradiol benzoate (EB), sold under the brand name Progynon-B among others, is an estrogen medication which is used in hormone therapy for menopausal symptoms and low estrogen levels in women, in hormone therapy for transgender women, and in the treatment of gynecological disorders. It is also used in the treatment of prostate cancer in men. Estradiol benzoate is used in veterinary medicine as well. When used clinically, the medication is given by injection into muscle usually two to three times per week.
Cypionate d'estradiolLe cypionate d'estradiol est un ester synthétique d' et d'estradiol, un œstrogène naturel. Il est absorbé plus lentement que l'estradiol lui-même, ce qui permet de l'administrer moins souvent. Parmi les esters d'estradiol couramment utilisés, le cypionate d'estradiol est celui qui reste actif le plus longtemps dans l'organisme, avec une durée d'action d'environ , contre pour le et pour le . Il fait partie de la liste des médicaments essentiels de l'Organisation mondiale de la santé (liste mise à jour en avril 2013).
