Estradiol Aq. soln. ? <1 d [1]
Oil soln. 40–60 1–2 ≈ 1–2 d [2] [3]
Aq. susp. ? 3.5 0.5–2 ≈ 2–7 d; 3.5 ≈ >5 d [2] [4] [5] [6] [7]
Microsph. ? 1 ≈ 30 d [8] [9]
Estradiol benzoate Oil soln. 25–35 1.66 ≈ 2–3 d; 5 ≈ 3–6 d [10] [11]
Aq. susp. 20 10 ≈ 16–21 d [12] [13] [14]
Emulsion ? 10 ≈ 14–21 d [14] [15]
Estradiol dipropionate Oil soln. 25–30 5 ≈ 5–8 d [10]
Estradiol valerate Oil soln. 20–30 5 5 ≈ 7–8 d; 10 ≈ 10–14 d;
40 ≈ 14–21 d; 100 ≈ 21–28 d
[11] [16]
Estradiol benz. butyrate Oil soln. ? 10 10 ≈ 21 d [17] [18]
Estradiol cypionate Oil soln. 20–30 5 ≈ 11–14 d [11]
Aq. susp. ? 5 5 ≈ 14–24 d [19] [20] [21]
Estradiol enanthate Oil soln. ? 5–10 10 ≈ 20–30 d [22] [23] [24]
Estradiol dienanthate Oil soln. ? 7.5 ≈ >40 d [25] [26]
Estradiol undecylate Oil soln. ? 10–20 ≈ 40–60 d;
25–50 ≈ 60–120 d
[27] [28]
Polyestradiol phosphate Aq. soln. 40–60 40 ≈ 30 d; 80 ≈ 60 d;
160 ≈ 120 d
[29] [30]
Estrone Oil soln. ? 1–2 ≈ 2–3 d [3] [31]
Aq. susp. ? 0.1–2 ≈ 2–7 d [32]
Estriol Oil soln. ? 1–2 ≈ 1–4 d [3] [33]
Polyestriol phosphate Aq. soln. ? 50 ≈ 30 d; 80 ≈ 60 d
Notes and sources
Notes: All aqueous suspensions are of microcrystalline particle size. Estradiol production during the menstrual cycle is 30–640 µg/d (6.4–8.6 mg total per month or cycle). The vaginal epithelium maturation dosage of estradiol benzoate or estradiol valerate has been reported as 5 to 7 mg/week. An effective ovulation-inhibiting dose of estradiol undecylate is 20–30 mg/month. Sources: Main/General: [34] [35] [36] [37] [38] [39] [40] [41] [42] Miscellaneous: [43] [44] [45]
