Conjugated B/synthetic estrogens contain a mixture of 10 synthetic estrogen substances, including sodium estrone sulfate, sodium equilin sulfate, sodium 17-alpha-dihydroequilin, sodium 17-alpha-estradiol, and sodium 17-beta-dihydroequilin. Estrogens are responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Estradiol is the principle intracellular human estrogen and is more potent than estrone and estriol at the receptor level; it is the primary estrogen secreted prior to menopause. Following menopause, estrone and estrone sulfate are more highly produced. Estrogens modulate the pituitary secretion of gonadotropins, luteinizing hormone, and follicle-stimulating hormone through a negative feedback system; estrogen replacement reduces elevated levels of these hormones in postmenopausal women.

Hepatic via CYP3A4; estradiol is converted to estrone and estriol; also undergoes enterohepatic recirculation; estrone sulfate is the main metabolite in postmenopausal women
Urine (primarily estriol, also as estradiol, estrone, and conjugates)
Conjugated estrone: 8-20 hours; conjugated equilin: 5-17 hours
Sex hormone-binding globulin (SHBG) and albumin
Use: Labeled Indications
Vasomotor symptoms associated with menopause: Treatment of moderate to severe vasomotor symptoms associated with menopause
Vulvar and vaginal atrophy associated with menopause: Treatment of moderate to severe vaginal dryness and pain with intercourse, symptoms of vulvar and vaginal atrophy, associated with menopause
Limitations of use: When used solely for the treatment of vulvar and vaginal atrophy, topical vaginal products should be considered.
Note: The International Society for the Study of Women’s Sexual Health and The North American Menopause Society have endorsed the term genitourinary syndrome of menopause (GSM) as new terminology for vulvovaginal atrophy. The term GSM encompasses all genital and urinary signs and symptoms associated with a loss of estrogen due to menopause (Portman 2014).
Undiagnosed abnormal genital bleeding; DVT or PE (current or history of); active or history of arterial thromboembolic disease (eg, stroke, MI); breast cancer (known, suspected or history of); estrogen-dependent tumor (known or suspected); liver impairment or disease; known protein C, protein S, antithrombin deficiency or other known thrombophilic disorders; pregnancy
Note: Enjuvia has been discontinued in the US for more than 1 year.
General dosing guidelines: When treating symptoms of menopause, hormone therapy should be evaluated routinely for appropriate dose, duration, and route of administration for each individual patient based on treatment goals, risk factors, and overall health (NAMS 2017). Combined estrogen/progestin therapy is indicated for postmenopausal persons with a uterus to decrease the risk of endometrial cancer. Individuals who have had a hysterectomy generally do not need a progestin; however, one may be needed if there is a history of endometriosis. Adjust dose based on patient response.
Vasomotor symptoms associated with menopause: Oral: Initial: 0.3 mg/day
Vulvar and vaginal atrophy associated with menopause: Oral: 0.3 mg/day
Note: Women >65 years of age should be assessed for benefits and risks of treatment; possible adjustments to safer lower-dose and/or route of administration should be considered (ACOG 565 2013; NAMS 2017). The Beers Criteria recommends avoiding systemic estrogen therapy in patients ≥65 years of age (independent of diagnosis or condition) (Beers Criteria [AGS 2019]).

Concerns related to adverse effects:
• Breast cancer: [US Boxed Warning]: Based on data from the Women’s Health Initiative (WHI) studies, an increased risk of invasive breast cancer was observed in postmenopausal women using conjugated estrogens (CE) in combination with medroxyprogesterone acetate (MPA). Observational studies noted this risk declines once therapy is discontinued. The WHI study did not observe an increased risk of invasive breast cancer in women with a hysterectomy using CE alone. The risk of breast cancer in postmenopausal patients on hormone therapy may depend upon type of estrogen and/or progestin, dose, timing of therapy initiation, duration of therapy, route of administration, and individual patient characteristics (AACE/ACE [Cobin 2017]; NAMS 2017). Hormone therapy may be associated with increased breast density (NAMS 2017); an increase in abnormal mammogram findings requiring further evaluation has been reported with estrogen alone or in combination with progestin therapy. Estrogen use may lead to severe hypercalcemia in patients with breast cancer and bone metastases; discontinue estrogen if hypercalcemia occurs.
• Dementia: [US Boxed Warning]: Estrogens with or without progestin should not be used to prevent dementia. In the Women’s Health Initiative Memory Study (WHIMS), an increased incidence of probable dementia was observed in women ≥65 years of age taking CE alone or in combination with MPA. Because the WHI memory studies were conducted in women ≥65 years of age, it is unknown if these findings apply to younger postmenopausal women. However, hormone therapy is not recommended at any age to prevent or treat cognitive decline or dementia (AACE [Goodman 2011]; NAMS 2017).
• Endometrial cancer: [US Boxed Warning]: The use of unopposed estrogen in women with a uterus is associated with an increased risk of endometrial cancer. The addition of a progestin to estrogen therapy may decrease the risk of endometrial hyperplasia, a precursor to endometrial cancer. Adequate diagnostic measures, including endometrial sampling if indicated, should be performed to rule out malignancy in postmenopausal women with undiagnosed abnormal vaginal bleeding. There is no evidence that the use of natural estrogens results in a different endometrial risk profile than synthetic estrogens at equivalent estrogen doses. The risk of endometrial cancer appears to be dose and duration dependent, greatest with use ≥5 years, and may persist following discontinuation of therapy. The use of a progestin is not generally required when low doses of estrogen are used locally for vaginal atrophy, although long-term data (>1 year) supporting this recommendation are lacking (NAMS 2013; NAMS 2017).
• Estrogens may exacerbate endometriosis. Malignant transformation of residual endometrial implants has been reported posthysterectomy with unopposed estrogen therapy. Consider adding a progestin in women with residual endometriosis posthysterectomy.
• Lipid effects: Estrogen compounds are generally associated with lipid effects such as increased HDL-cholesterol and decreased LDL-cholesterol. Triglycerides may also be increased in women with preexisting hypertriglyceridemia; discontinue if pancreatitis occurs.
• Ovarian cancer: Available information related to the use of menopausal estrogen or estrogen/progestin therapy and risk of ovarian cancer is inconsistent. If an association is present, the absolute risk is likely rare and may be influenced by duration of therapy (AACE [Goodman 2011]; ES [Stuenkel 2015]; NAMS 2017).
• Retinal vascular thrombosis: Estrogens may cause retinal vascular thrombosis; discontinue if migraine, loss of vision, proptosis, diplopia, or other visual disturbances occur; discontinue permanently if papilledema or retinal vascular lesions are observed on examination.
• Asthma: Use caution in patients with asthma; may exacerbate disease.
• Carbohydrate intolerance: May impair glucose tolerance; use caution in patients with diabetes. Prior to therapy, consider age, cardiovascular and metabolic risk factors in patients previously diagnosed with diabetes (AACE/ACE [Cobin 2017]).
• Cardiovascular disease: [US Boxed Warning]: Estrogens with or without progestin should not be used to prevent cardiovascular disease. Using data from the Women’s Health Initiative (WHI) studies, an increased risk of deep vein thrombosis (DVT) and stroke has been reported with CE and an increased risk of DVT, stroke, pulmonary emboli (PE) and myocardial infarction (MI) has been reported with CE with MPA in postmenopausal women 50 to 79 years of age. Additional risk factors include diabetes mellitus, hypercholesterolemia, hypertension, SLE, obesity, tobacco use, and/or history of venous thromboembolism (VTE). Risk factors should be managed appropriately; discontinue use immediately if adverse cardiovascular events occur or are suspected. Due to possible lower risk of thrombotic events, transdermal administration may be preferred for treating vasomotor symptoms of menopause in patients with risk factors for cardiovascular disease (AACE/ACE [Cobin 2017]; ACOG 556 2013; ES [Stuenkel 2015]). Use is contraindicated in women with active DVT, PE, arterial thromboembolic disease (stroke and MI), or a history of these conditions.
• Diseases exacerbated by fluid retention: Use with caution in patients with diseases that may be exacerbated by fluid retention, including cardiac or renal dysfunction.
• Epilepsy: Use caution with epilepsy; may exacerbate disease.
• Gallbladder disease: Use of postmenopausal estrogen may be associated with an increased risk of gallbladder disease requiring surgery.
• Hepatic dysfunction: Estrogens are poorly metabolized in patients with hepatic dysfunction. Use caution with a history of cholestatic jaundice associated with prior estrogen use or pregnancy. Discontinue if jaundice develops or if acute or chronic hepatic disturbances occur. Use is contraindicated with hepatic impairment or disease.
• Hepatic hemangiomas: Use with caution in patients with hepatic hemangiomas; may exacerbate disease.
• Hereditary angioedema: Exogenous estrogens may exacerbate angioedema symptoms in women with hereditary angioedema.
• Hypoparathyroidism: Use caution with hypoparathyroidism; estrogen-induced hypocalcemia may occur.
• Migraine: Use caution with migraine; may exacerbate disease.
• Porphyria: Use with caution in patients with porphyria; may exacerbate disease.
• SLE: Use with caution in patients with SLE; may exacerbate disease.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information
• Thyroid replacement therapy: Estrogens may increase thyroid-binding globulin (TBG) levels leading to increased circulating total thyroid hormone levels. Women on thyroid replacement therapy may require higher doses of thyroid hormone while receiving estrogens.
• Surgical patients: Whenever possible, estrogens should be discontinued at least 4 to 6 weeks prior to elective surgery associated with an increased risk of thromboembolism or during periods of prolonged immobilization.
• Duration of use: Extended use of menopausal hormone therapy may be considered for persistent vasomotor symptoms, or issues related to quality of life. Menopausal hormonal therapy does not need to be routinely discontinued in women >60 years of age and may continue in women >65 years of age after clinical evaluation and discussion of benefits and risks of treatment. Annual exams should be performed with a review of comorbidities; possible adjustments to safer lower-dose and/or route of administration should be discussed (ACOG 565 2013; NAMS 2017).
• Genitourinary syndrome of menopause (GSM): Low dose vaginal estrogen is preferred over systemic therapy for GSM in the absence of vasomotor symptoms due to increased efficacy and decreased systemic effects (eg, cardiovascular effects, cancer risk) (Crandall 2018; NAMS 2013; NAMS 2017).
• Laboratory changes: The use of estrogens and/or progestins may change the results of some laboratory tests (eg, coagulation factors, lipids, glucose tolerance, binding proteins). The dose, route, and the specific estrogen/progestin influence these changes.
• Risks vs benefits: When used for the relief of menopausal symptoms or increased risk of bone fracture/loss, the benefit-risk of hormone therapy is most favorable if started in patients who have no contraindications to therapy, are <60 years of age, within 10 years of menopause onset, have a favorable lipid profile, and do not have the factor V Leiden genotype or metabolic syndrome. Risk factors for cardiovascular disease should also be considered when evaluating therapy and route of administration (AACE/ACE [Cobin 2017]; NAMS 2017). [US Boxed Warning]: Estrogens with or without progestin should be used for the shortest duration possible at the lowest effective dose consistent with treatment goals and risks for the individual woman. Patients should be reevaluated as clinically appropriate to determine if treatment is still necessary. Available data related to treatment risks are from Women’s Health Initiative (WHI) studies, which evaluated oral CE 0.625 mg with or without MPA 2.5 mg relative to placebo in postmenopausal women. Other combinations and dosage forms of estrogens and progestins were not studied. Outcomes reported from clinical trials using CE with or without MPA should be assumed to be similar for other doses and other dosage forms of estrogens and progestins until comparable data becomes available.
Prior to therapy, baseline risk for breast cancer and CVD. During therapy, age appropriate breast and pelvic exams; blood pressure; unscheduled bleeding lasting >6 months for endometrial pathology (sooner in patients who are obese, diabetic, or have a history of endometrial cancer); serum triglycerides (2 weeks after starting therapy in patients with baseline level >200 mg/dL); TSH (6 to 12 weeks after starting oral therapy in patients taking thyroid replacement); efficacy beginning 1 to 3 months after starting therapy, then every 6 to 12 months as appropriate. Duration of treatment should be evaluated at least annually (ES [Stuenkel 2015]).
Note: Monitoring of FSH and serum estradiol is not useful when managing vasomotor symptoms or GSM.
Use is contraindicated in pregnant women.
In general, the use of estrogen and progestin as in combination hormonal contraceptives have not been associated with teratogenic effects when inadvertently taken early in pregnancy.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience flatulence, cramps, bloating, or hair loss. Have patient report immediately to prescriber signs of severe cerebrovascular disease (change in strength on one side is greater than the other, difficulty speaking or thinking, change in balance, or vision changes), signs of DVT (edema, warmth, numbness, change in color, or pain in the extremities), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), angina, shortness of breath, coughing up blood, loss of strength and energy, severe headache, severe nausea, vomiting, severe dizziness, passing out, vision changes, bulging eyes, contact lens discomfort, lump in breast, breast soreness or pain, nipple discharge, vaginitis, vaginal bleeding, depression, memory impairment, edema, or burning or numbness feeling (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
