💊 Adverse Effects and Precautions

As for oestrogens in general. See also under Hormonal Contraceptives.

Effects on calcium homoeostasis.

Two patients with metastatic breast cancer given ethinylestradiol developed rapidly progressive irreversible and fatal hypercalcaemia, considered to be due to stimulation of osteolysis by the oestrogen.1

Effects on the liver.

Cholestasis and pruritus developed in a liver transplant recipient receiving ethinylestradiol at a dose of 50 micrograms daily for the treatment of menorrhagia.1 Symptoms subsided on withdrawal of ethinylestradiol but returned on its re-introduction.

💊 Pharmacokinetics

Ethinylestradiol is rapidly and well absorbed from the gastrointestinal tract. The presence of an ethinyl group at the 17-position greatly reduces hepatic first-pass metabolism compared with estradiol, enabling the compound to be much more active by mouth, but there is some initial conjugation by the gut wall, and the systemic bioavailability is only about 40%. Ethinylestradiol is highly protein bound, but unlike naturally occurring oestrogens, which are mainly bound to sexhormone binding globulin, it is principally bound to albumin. It is metabolised in the liver, initially by aromatic hydroxylation catalysed by the cytochrome P450 isoenzyme CYP3A4, to form 2-hydroxyethinylestradiol and various conjugated metabolites. These are excreted in urine and faeces. Metabolites undergo enterohepatic recycling.

💊 Uses and Administration

Ethinylestradiol is a synthetic oestrogen with actions similar to those of estradiol. It is frequently used as the oestrogenic component of combined oral contraceptive preparations; a typical daily dose is 20 to 40 micrograms. Ethinylestradiol betadex clathrate has been used similarly in combined oral contraceptives. Ethinylestradiol is also used in a combined contraceptive transdermal patch. A dose of 20 micrograms ethinylestradiol is released daily with norelgestromin. A new patch is applied each week for 3 weeks of a 4-week cycle. Oestrogen exposure from such a patch may be higher than with a comparable oral contraceptive. A combined contraceptive vaginal ring device delivering an average of 15 micrograms ethinylestradiol daily with etonogestrel is also available; it remains in the vagina for 3 weeks and is then removed for a one-week break, after which a new ring is inserted. Ethinylestradiol has also been used orally as an emergency contraceptive combined with levonorgestrel or norgestrel. A combined preparation of ethinylestradiol with the anti-androgen cyproterone is used for the hormonal treatment of acne and hirsutism, particularly when contraception is also required. Ethinylestradiol has also been used for menopausal HRT, although natural oestrogens are usually preferred. Oral doses of 10 to 50 micrograms daily have been given cyclically (with a progestogen in women with a uterus), but preparations providing lower doses of 2.5 or 5 micrograms daily are also available. For the treatment of female hypogonadism, doses of 10 to 50 micrograms daily on a cyclical basis have been used. For the palliative treatment of prostate cancer doses of 150 micrograms to 3 mg have been given daily. For palliation of malignant neoplasms of the breast in postmenopausal women doses of 100 micrograms to 1 mg three times daily have been used.

Administration in children.

Although unlicensed in the UK for use in children, the BNFC does include doses of ethinylestradiol. An initial oral dose of 2 micrograms daily may be used in the management of delayed puberty in girls. This may be increased every 6 months to 5 micrograms, then to 10 micrograms, then to 20 micrograms daily, according to response. After 12 to 18 months of treatment, a progestogen should be added for 7 days of each 28-day cycle. A daily dose of ethinylestradiol 20 micrograms with cyclical progestogen may then be used to maintain sexual maturation. For the prevention of constitutional tall stature, ethinylestradiol may be given to girls aged 2 to 12 years old in a dose of 20 to 50 micrograms daily. Growth hormone provocation testing may be used in the diagnosis of growth hormone deficiency in children with growth retardation. However, the response can be blunted in prepubertal and peripubertal children, resulting in false negative results. Hormonal pituitary priming using ethinylestradiol has been tried in both boys and girls in order to increase responsiveness to the test,1,2 although there appears to be no consensus on such use.3 The BNFC includes an oral dose of 100 micrograms daily for 3 days before the test, for girls with a bone age above 10 years.
