Pharmacology

Estropipate is prepared from naturally occurring estrone. 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. In males and following menopause in females, 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. Estropipate is prepared from purified crystalline estrone that has been solubilized as the sulfate and stabilized with piperazine.

Absorption

Well absorbed

Distribution

Widely distributed; high concentrations in the sex hormone target organs.

Metabolism

Hepatic; partial metabolism via CYP3A4 enzymes; estradiol is reversibly converted to estrone and estriol; estrogens also undergo enterohepatic recirculation by conjugation in the liver, followed by excretion of sulfate and glucuronide conjugates into the bile, then hydrolysis in the intestine and estrogen reabsorption. Sulfate conjugates are the primary form found in postmenopausal women.

Excretion

Primarily urine (as estradiol, estrone, estriol and their glucuronide and sulfate conjugates).

Protein Binding

Bound to sex hormone-binding globulin and albumin.

Use: Labeled Indications

Hypoestrogenism, female: Treatment of hypoestrogenism due to hypogonadism, castration, or primary ovarian failure.

Osteoporosis prevention: Prevention of postmenopausal osteoporosis.

Vasomotor symptoms associated with menopause: Treatment of moderate to severe vasomotor symptoms associated with menopause.

Vulval and vaginal atrophy associated with menopause: Treatment of moderate to severe symptoms of vulval 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. When used for osteoporosis prevention, use only in women at significant risk of postmenopausal osteoporosis; consider use of nonestrogen medications

Contraindications

Hypersensitivity to estrogens or any component of the formulation; 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); hepatic impairment or disease; pregnancy.

Documentation of allergenic cross-reactivity for estrogens is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.

Dosing: Adult

Female: General dosing guidelines: When treating postmenopausal women, use estrogens for the shortest duration possible at the lowest effective dose consistent with treatment goals. Reevaluate patients as clinically appropriate to determine if treatment is still necessary. Consider use of an estrogen with a progestin in postmenopausal women with a uterus. Women who have had a hysterectomy generally do not need a progestin; however one may be needed if there is a history of endometriosis. Dosage needs to be adjusted based upon the patient's response

Hypoestrogenism (female) due to castration or primary ovarian failure: Oral: 1.5 to 9 mg daily for the first 3 weeks of a theoretical cycle, followed by a rest period of 8 to 10 days

Hypoestrogenism (female) due to hypogonadism: Oral: 1.5 to 9 mg daily for the first 3 weeks of a theoretical cycle, followed by a rest period of 8 to 10 days. Repeat if bleeding does not occur by the end of the rest period. The duration of therapy necessary to product the withdrawal bleeding will vary according to the responsiveness of the endometrium. If satisfactory withdrawal bleeding does not occur, give an oral progestin in addition to estrogen during the third week of the cycle.

Osteoporosis prevention: Oral: 0.75 mg daily for 25 days of a 31-day cycle

Vasomotor symptoms associated with menopause: Oral: 0.75 to 6 mg daily. If a patient with vasomotor symptoms has not menstruated within the last ≥2 months, start the cyclic administration arbitrarily. If the patient has menstruated, start cyclic administration on day 5 of bleeding.

Vulvar and vaginal atrophy associated with menopause: Oral: 0.75 to 6 mg daily; administer cyclically.

ALERT: U.S. Boxed Warning

Endometrial cancer:

Estrogens increase the risk of endometrial cancer. Close clinical surveillance of all women taking estrogens is important. Adequate diagnostic measures, including endometrial sampling when indicated, to rule out malignancy in all cases of undiagnosed persistent or recurring abnormal vaginal bleeding. There is no evidence that the use of "natural" estrogens result in a different endometrial risk profile than "synthetic" estrogens at equivalent estrogen doses

Cardiovascular disease:

Estrogens with and without progestins should not be used for the prevention of cardiovascular disease. The Women's Health Initiative (WHI) study reported increased risks of myocardial infarction, stroke, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years of age) during 5 years of treatment with oral conjugated estrogens (0.625 mg) combined with medroxyprogesterone (2.5 mg), relative to placebo.

Breast cancer:

The Women's Health Initiative (WHI) study reported increased risks of invasive breast cancer in postmenopausal women (50 to 79 years of age) during 5 years of treatment with oral conjugated estrogens (0.625 mg) combined with medroxyprogesterone (2.5 mg) relative to placebo.

Dementia:

The Women's Health Initiative Memory Study (WHIMS) a substudy of WHI, reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with oral conjugated estrogens plus medroxyprogesterone relative to placebo. It is unknown whether this finding applies to younger postmenopausal women or to women taking estrogen alone therapy.

Risks vs. benefits:

Other doses of conjugated estrogens with medroxyprogesterone, and other combinations and dosage forms of estrogens and progestins were not studied in the WHI clinical trials and, in the absence of comparable data, these risks should be assumed to be similar. Because of these risks, estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

Warnings/Precautions

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). This risk may be associated with duration of use and declines once combined therapy is discontinued (Chlebowski 2009). The risk of invasive breast cancer was decreased in postmenopausal women with a hysterectomy using CE only, regardless of weight. However, the risk was not significantly decreased in women at high risk for breast cancer (family history of breast cancer, personal history of benign breast disease) (Anderson 2012). An increase in abnormal mammogram findings has also been reported with estrogen alone or in combination with progestin therapy. Estrogen use may also lead to severe hypercalcemia in patients with breast cancer and bone metastases; discontinue estrogen if hypercalcemia occurs. Use is contraindicated in patients with known or suspected breast cancer.

• 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.

• 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; risk appears to be greatest with use ≥5 years and may persist following discontinuation of therapy (NAMS 2012; NAMS 2013).

• Endometriosis: 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.

• Inherited thrombophilia: Women with inherited thrombophilias (eg, protein C or S deficiency) may have increased risk of venous thromboembolism (DeSancho 2010; van Vlijmen 2011).

• 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: Postmenopausal estrogens with or without progestins may increase the risk of ovarian cancer; however, the absolute risk to an individual woman is small. Although results from various studies are not consistent, risk does not appear to be significantly associated with the duration, route, or dose of therapy. In one study, the risk decreased after 2 years following discontinuation of therapy (Mørch 2009). Although the risk of ovarian cancer is rare, women who are at an increased risk (eg, family history) should be counseled about the association (NAMS 2012).

• 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.

Disease-related concerns:

• Asthma: Use caution in patients with asthma; may exacerbate disease.

• Carbohydrate intolerance: May have adverse effects on glucose tolerance; use caution in women with diabetes.

• 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 if adverse cardiovascular events occur or are suspected. Use is contraindicated in women with active DVT or PE (or a history of these conditions) or in women with active or recent arterial thromboembolic disease (stroke and MI), or a history of these conditions.

• Diseases exacerbated by fluid retention: Use with caution in patients with diseases which 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.

• Hypocalcemia: Use with caution in patients with severe hypocalcemia.

• 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.

Special populations:

• Elderly: Although hormone therapy is recommended to be initiated in healthy symptomatic women within 10 years of menopause or <60 years of age who do not have contraindications for use, symptoms may continue in women >60 years of age. The continuation of hormone therapy in women >65 years of age should consider the risks and benefits for the individual woman and should not be discontinued only because of the woman’s age (NAMS 2015).

• 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.

Special handling:

• Hazardous agent: Use appropriate precautions for handling and disposal (NIOSH 2014 [group 2]).

Other warnings/precaution:

• 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. In addition, personal risk factors (eg, cardiovascular disease, smoking, diabetes, age) also contribute to adverse events; use of specific products may be contraindicated in women with certain risk factors.

• Osteoporosis use: For use only in women at significant risk of osteoporosis and for who other nonestrogen medications are not considered appropriate.

• Risks vs benefits: [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. Hormone therapy for menopausal symptoms is generally initiated in healthy symptomatic women within 10 years of menopause or <60 years of age who do not have contraindications for use (Stuenkel 2015). 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. Women who are early in menopause, who are in good cardiovascular health, and who are at low risk for adverse cardiovascular events can be considered candidates for estrogen with or without progestin therapy for the relief of menopausal symptoms (ACOG 565 2013). Women at high risk of cardiovascular disease or intermediate to high risk of breast cancer should use nonhormonal therapy to treat vasomotor symptoms of menopause (Stuenkel 2015). Use of a transdermal product should be considered over an oral agent in women requiring systemic therapy who have moderate risk factors for coronary heart disease (ACOG 556 2013; Schenck-Gustafsson 2011; Stuenkel 2015). Nonoral routes of therapy are recommended for women at increased risk for venous thromboembolism (Stuenkel 2015; Tremollieres 2011)

• Vulvar and vaginal atrophy use: Moderate to severe symptoms of vulvar and vaginal atrophy include vaginal dryness, dyspareunia, and atrophic vaginitis. [The combined conditions of vulvovaginal atrophy and urinary tract dysfunction is also referred to as genitourinary syndrome of menopause (GSM) (Portman 2014; Stuenkel 2015)]. When used solely for the treatment of vulvar and vaginal atrophy, topical vaginal products should be considered (NAMS 2012; NAMS 2013; Stuenkel 2015).

Monitoring Parameters

Routine physical examination that includes blood pressure and Papanicolaou smear, breast exam, mammogram. Monitor for signs of endometrial cancer in female patients with a uterus. Adequate diagnostic measures, including endometrial sampling, if indicated, should be performed to rule out malignancy in all cases of undiagnosed abnormal genital bleeding. Monitor for loss of vision, sudden onset of proptosis, diplopia, migraine; signs and symptoms of thromboembolic disorders; glycemic control in patients with diabetes; lipid profiles in patients being treated for hyperlipidemias; thyroid function in patients on thyroid hormone replacement therapy.

Menopausal symptoms: Assess need for therapy at 3- to 6-month intervals

Prevention of osteoporosis: Bone density measurement

Note: Monitoring of FSH and serum estradiol is not useful when managing vasomotor symptoms associated with menopause or vulvar and vaginal atrophy.

Pregnancy Considerations

Use is contraindicated in pregnant women. In general, the use of estrogen and progestin as in combination hormonal contraceptives has not been associated with teratogenic effects when inadvertently taken early in pregnancy.

Patient Education

• 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 hair loss, cramps, bloating, or dark patches on face. 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), angina, edema, shortness of breath, coughing up blood, 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, vaginal bleeding, vaginitis, depression, or memory impairment (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.
