Equine estrogens, or horse estrogens ... Binding affinities were determined via displacement studies in a variety of in-vitro systems with labeled estradiol and ...
Conjugated estrogens (CEs), or conjugated equine estrogens (CEEs), sold under the brand name Premarin among others, is an estrogen medication which is used in menopausal hormone therapy and for various other indications.
Tritiated estradiol radioactivity in blood with a single intramuscular injection of 1.5 to 2.8 μg tritiated estradiol in aqueous solution in four women. [1] Peak blood radioactivity occurred within 15 minutes in three of the women and in the remaining woman after 2 hours. [1] Source: Davis et al. (1963). [1]
Average number of moderate-to-severe hot flashes per week with placebo and different doses of oral estradiol in menopausal women [40] [41]. Estradiol is used in menopausal hormone therapy to prevent and treat moderate to severe menopausal symptoms such as hot flashes, vaginal dryness and atrophy, and osteoporosis (bone loss). [11]
Daily intramuscular injections of 1 mg estradiol benzoate in oil solution have been found to produce estradiol excretion rates almost double those of the normal luteal phase. [66] [74] [75] This is in accordance with known production rates of estradiol in women (e.g., 300 μg/day in the luteal phase). [66] [76]
In premenopausal women the majority of estrogen produced by the body is estradiol (produced primarily in the ovaries), while in postmenopausal women estrone (produced in fat cells) is the type of primary estrogen present; however, the body is able to convert one type of estrogen into another to a certain extent.
Estradiol: 25 μg/day b: 50 μg/day b: 100 μg/day b: Transdermal gel: Estradiol: 0.5 mg/day: 1–1.5 mg/day: 2–3 mg/day Vaginal: Estradiol: 25 μg/day – – Estriol: 30 μg/day: 0.5 mg 2x/week: 0.5 mg/day IM Tooltip Intramuscular or SC injection: Estradiol valerate – – 4 mg 1x/4 weeks Estradiol cypionate: 1 mg 1x/3–4 weeks: 3 mg 1x/3 ...
Estrone in oil solution by intramuscular injection is rapidly absorbed, while estrone in aqueous suspension has a prolonged period of absorption. [62] Upon intramuscular injection of estrone in aqueous solution, the water from the preparation is absorbed and a microcrystalline depot of estrone that is slowly absorbed by the body is formed. [37]
