Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🚨 Boxed Warning ~3 min read ▾

WARNING: ENDOMETRIAL CANCER, CARDIOVASCULAR DISORDERS, PROBABLE DEMENTIA and BREAST CANCER Estrogen-Alone Therapy Endometrial Cancer There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Perform adequate diagnostic measures, including directed or random endometrial sampling when indicated, to rule out malignancy in postmenopausal women with undiagnosed, persistent or recurring abnormal genital bleeding [see Warnings and Precautions (5.2) ] .

Cardiovascular Disorders and Probable Dementia Do not use estrogen-alone therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1 , 5.3) , and Clinical Studies (14.2 , 14.3) ] . The Women’s Health Initiative (WHI) estrogen-alone substudy reported increased risks of stroke and deep vein thrombosis (DVT) in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] - alone, relative to placebo [see Warnings and Precautions (5.1) , and Clinical Studies (14.2) ] .

The WHI Memory Study (WHIMS) estrogen-alone ancillary study of the WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 5.2 years of treatment with daily CE (0.625 mg)-alone, relative to placebo. It is unknown whether this finding applies to younger postmenopausal women [see Warnings and Precautions (5.3) , Use in Specific Populations (8.5) , and Clinical Studies (14.3) ] . Only daily oral 0.625 mg CE was studied in the estrogen-alone substudy of WHI.

Therefore, the relevance of the WHI findings regarding adverse cardiovascular events and dementia to lower CE doses, other routes of administration, or other estrogen-alone products is not known. Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products. Discuss with your patient the benefits and risks of estrogen-alone therapy, taking into account her individual risk profile.

Prescribe estrogens with or without progestins at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman. Estrogen Plus Progestin Therapy Cardiovascular Disorders and Probable Dementia Do not use estrogen plus progestin therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1 , 5.3) , and Clinical Studies (14.2 , 14.3) ] . The WHI estrogen plus progestin substudy reported increased risks of DVT, pulmonary embolism (PE), stroke and myocardial infarction (MI) in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with daily oral CE (0.625 mg) combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo [see Warnings and Precautions (5.1) , and Clinical Studies (14.2) ] .

The WHIMS estrogen plus progestin ancillary study of the WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with daily CE (0.625 mg) combined with MPA (2.5 mg), relative to placebo. It is unknown whether this finding applies to younger postmenopausal women [ see Warnings and Precautions (5.3) , Use in Specific Populations (8.5) , and Clinical Studies (14.3) ] . Breast Cancer The WHI estrogen plus progestin substudy also demonstrated an increased risk of invasive breast cancer [see Warnings and Precautions (5.2) , and Clinical Studies (14.2) ].

Only daily oral 0.625 mg CE and 2.5 mg MPA were studied in the estrogen plus progestin substudy of WHI. Therefore, the relevance of the WHI findings regarding adverse cardiovascular events, dementia and breast cancer to lower CE plus other MPA doses, other routes of administration, or other estrogen plus progestin products is not k… [Excerpted — this section continues on DailyMed.]

🎯 Indications and Usage 35 words ▾

1 INDICATIONS AND USAGE ELESTRIN is an estrogen indicated for the treatment of moderate to severe vasomotor symptoms due to menopause ( 1.1 )

1.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause

⏱️ Dosage and Administration ~1 min read ▾

2 DOSAGE AND ADMINISTRATION Generally, when estrogen is prescribed for a postmenopausal woman with a uterus, consider addition of a progestin to reduce the risk of endometrial cancer. Generally, a woman without a uterus does not need to take a progestin in addition to her estrogen therapy. In some cases, however, hysterectomized women who have a history of endometriosis may need a progestin [see Warnings and Precautions (5.2) , (5.14) ] .

Use estrogen-alone, or in combination with a progestin, at the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Reevaluate postmenopausal women periodically as clinically appropriate to determine if treatment is still necessary. ELESTRIN is applied onto the skin in a thin layer.

The recommended area of application is the upper arm to shoulder (approximately 320 cm 2 ). Start therapy with daily administration of one pump actuation to deliver 0.87 grams of gel providing 0.52 mg estradiol to the upper arm. Dosage adjustment should be guided by the clinical response ( 2.1 )

2.1Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause ELESTRIN is applied once daily to the upper arm for the treatment of moderate to severe vasomotor symptoms due to menopause using a metered-dose pump which delivers 0.87 grams of estradiol gel (0.52 mg estradiol) per actuation (1 pump). Start therapy with one pump per day (0.87 grams per day, which contains 0.52 mg of estradiol). Make dosage adjustments based on clinical response.

💊 Dosage Forms and Strengths 42 words ▾

3 DOSAGE FORMS AND STRENGTHS ELESTRIN is available in a metered dose pump which delivers 0.52 mg of estradiol in 0.87 grams of gel per pump actuation. Metered dose pump: 0.87 grams of gel per pump actuation delivers 0.52 mg of estradiol

⛔ Contraindications ~1 min read ▾

4 CONTRAINDICATIONS ELESTRIN is contraindicated in women with any of the following conditions: • Undiagnosed abnormal genital bleeding [see Warnings and Precautions (5.2) ] . • Breast cancer or a history of breast cancer [see Warnings and precautions (5.2) ] . • Estrogen-dependent neoplasia [see Warnings and Precautions (5.2) ] . • Active DVT, PE, or history of these conditions [see Warnings and Precautions (5.1) ] . • Active arterial thromboembolic disease (for example, stroke and MI) or a history of these conditions [see warnings and Precautions (5.1) ] . • Known anaphylactic reaction, or angioedema, or hypersensitivity to ELESTRIN. • Hepatic impairment or disease. • Protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders. • Undiagnosed abnormal genital bleeding ( 4 ) • Breast cancer or a history of breast cancer ( 4 , 5.2 ) • Estrogen-dependent neoplasia ( 4 , 5.2 ) • Active DVT, PE, or history of these conditions ( 4 , 5.1 ) • Active arterial thromboembolic disease (for example, stroke and MI) or a history of these conditions ( 4 , 5.1 ) • Known anaphylactic reaction or angioedema or hypersensitivity with ELESTRIN ( 4 ) • Hepatic impairment or disease ( 4 , 5.10 ) • Protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders ( 4 )

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS • Estrogens increase the risk of gallbladder disease ( 5.4 ) • Discontinue estrogen if severe hypercalcemia, loss of vision, severe hypertriglyceridemia or cholestatic jaundice occurs ( 5.5 , 5.6 , 5.9 , 5.10 ) • Monitor thyroid function in women on thyroid replacement therapy ( 5.11 , 5.21 )

5.1Cardiovascular Disorders Increased risk of stroke and DVT are reported with estrogen-alone therapy. Increased risk of PE, DVT, stroke and MI are reported with estrogen plus progestin therapy. Immediately discontinue estrogen with or without progestin therapy if any of these occur or is suspected.

Manage appropriately any risk factors for arterial vascular disease (for example, hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (VTE) (for example, personal history or family history of VTE, obesity, and systemic lupus erythematosus). Stroke The WHI estrogen-alone substudy reported a statistically significant increased risk of stroke in women 50 to 79 years of age receiving daily CE (0.625 mg)-alone compared to women in the same age group receiving placebo (45 versus 33 strokes per 10,000 women-years, respectively).

The increase in risk was demonstrated in year 1 and persisted [see Clinical Studies (14.2) ] . Immediately discontinue estrogen-alone therapy if a stroke occurs or is suspected. Subgroup analyses of women 50 to 59 years of age suggest no increased risk of stroke for those women receiving CE (0.625 mg)-alone versus those receiving placebo (18 versus 21 per 10,000 women-years).

1 The WHI estrogen plus progestin substudy reported a statistically significant increased risk of stroke in women 50 to 79 years of age receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women in the same age group receiving placebo (33 versus 25 strokes per 10,000 women-years) [see Clinical Studies (14.2) ] . The increase in risk was demonstrated after the first year and persisted. 1 Immediately discontinue estrogen plus progestin therapy if a stroke occurs or is suspected.

Coronary Heart Disease The WHI estrogen-alone substudy reported no overall effect on coronary heart disease (CHD) events (defined as nonfatal MI, silent MI and CHD death) in women receiving estrogen-alone compared to placebo 2 [see Clinical Studies (14.2) ] . Subgroup analyses of women 50 to 59 years of age, who were less than 10 years since menopause, suggest a reduction (not statistically significant) in CHD events in those women receiving daily CE (0.625 mg)-alone compared to placebo (8 versus 16 per 10,000 women-years).

1 The WHI estrogen plus progestin substudy reported an increased risk of CHD events (not statistically significant) in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (41 versus 34 per 10,000 women-years) 1 . An increase in relative risk was demonstrated in year 1, and a trend toward decreasing relative risk was reported in years 2 through 5 [see Clinical Studies (14.2) ] . In postmenopausal women with documented heart disease (n = 2,763, average 66.7 years of age), in a controlled clinical trial of secondary prevention of cardiovascular disease (Heart and Estrogen/Progestin Replacement Study; HERS) treatment with daily CE (0.625 mg) plus MPA (2.5 mg) demonstrated no cardiovascular benefit.

During an average follow-up of 4.1 years, treatment with CE plus MPA did not reduce the overall rate of CHD events in postmenopausal women with established coronary heart disease. There were more CHD events in the CE plus MPA-treated group than in the placebo group in year 1, but not during the subsequent years. Two thousand, three hundred and twenty-one (2,321) women from the original HERS trial agreed to participate in an open label extension of HERS, HERS II.

Average follow-up in HERS II was an additional 2.7 years, for a total of 6.8 years overall. Rates of CHD events were comparable among women in the CE plus MPA group and the placebo gr… [Excerpted — this section continues on DailyMed.]

🤒 Adverse Reactions ~2 min read ▾

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: • Cardiovascular Disorders [see Boxed Warning , and Warnings and Precautions (5.1) ]. • Malignant Neoplasms [see Boxed Warning , and Warnings and Precautions (5.2) ]. The most common adverse reactions (≥ 5 percent) in any ELESTRIN treatment group are: breast tenderness, metrorrhagia, nasopharyngitis, and upper respiratory tract infections. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Meda at 1-877-999-8401 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. ELESTRIN was studied in a placebo-controlled trial that included a total of 484 postmenopausal women. The adverse reactions that occurred at a rate greater than 5 percent in any of the treatment groups are summarized in Table 1.

TABLE 1 - Incidence of Treatment-Emergent Adverse Reactions Occurring in ≥ 5 Percent of Women Body System / Signs and Symptoms Number (%) of Women Placebo (n = 137) ELESTRIN 0.87 g/day (n = 136) ELESTRIN 1.7 g/day (n = 142) Reproductive system & breast disorders Breast tenderness 5 (3.6) 9 (6.6) 11 (7.7) Metrorrhagia 3 (2.2) 6 (4.4) 13 (9.2) Respiratory, thoracic & mediastinal disorders Nasopharyngitis 10 (7.3) 14 (10.3) 12 (8.5) Upper respiratory tract infection 5 (3.6) 8 (5.9) 5 (3.5)

6.2Postmarketing Experience The following adverse reactions have been identified during post-approval use of ELESTRIN. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

🔄 Drug Interactions 114 words ▾

7 DRUG INTERACTIONS In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4, such as St.

John’s wort (Hypericum perforatum) preparations, phenobarbital, carbamazepine, and rifampin, may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Inhibitors of CYP3A4, such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir, and grapefruit juice, may increase plasma concentrations of estrogens and result in adverse reactions. • Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentrations ( 7 )

5.21Drug-Laboratory Test Interactions • Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, VII-X complex, II-VII-X complex, and beta-thromboglobulin; decreased levels of anti-factor Xa and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity. • Increased thyroid binding globulin (TBG) levels leading to increased circulating total thyroid hormone levels as measured by protein-bound iodine (PBI), T 4 levels (by column or by radioimmunoassay) or T 3 levels by radioimmunoassay.

T 3 resin uptake is decreased, reflecting the elevated TBG. Free T 4 and free T 3 concentrations are unaltered. Women on thyroid replacement therapy may require higher doses of thyroid hormone. • Other binding proteins may be elevated in serum, for example, corticosteroid binding globulin (CBG), sex hormone-binding globulin (SHBG), leading to increased total circulating corticosteroids and sex steroids, respectively.

Free hormone concentrations, such as testosterone and estradiol, may be decreased. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-1-antitrypsin, ceruloplasmin). • Increased plasma high-density lipoprotein (HDL) and HDL 2 cholesterol subfraction concentrations, reduced low-density lipoprotein (LDL) cholesterol concentration, and increased triglycerides levels. • Impaired glucose tolerance.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary ELESTRIN is not indicated for use in pregnancy. There are no data with the use of ELESTRIN in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies or limb-reduction defects) following exposure to combined hormonal contraceptives (estrogen and progestins) before conception or during early pregnancy. Animal studies to evaluate embryo/fetal toxicity were not conducted with ELESTRIN.

8.2Lactation Risk Summary Estrogens are present in human milk and can reduce milk production in breast-feeding women. This reduction can occur at any time but is less likely to occur once breast-feeding is well-established. The developmental and health benefits of breast-feeding should be considered along with the mother’s clinical need for ELESTRIN and any potential adverse effects on the breast-fed child from ELESTRIN or from the underlying maternal condition.

8.4Pediatric Use ELESTRIN is not indicated in pediatric patients. Clinical studies have not been conducted in the pediatric population.

8.5Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing ELESTRIN to determine whether those over 65 years of age differ from younger subjects in their response to ELESTRIN. The Women’s Health Initiative Study In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was a higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies (14.2) ] . In the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age [see Clinical Studies (14.2) ] .

The Women’s Health Initiative Memory Study In the WHIMS ancillary studies of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dementia in women receiving estrogen-alone or estrogen plus progestin when compared to placebo [see Warnings and Precautions (5.3) , and Clinical Studies (14.3) ] . Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women 8 [see Warnings and Precautions (5.3) , and Clinical Studies (14.3) ] .

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Endogenous estrogens are largely responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Although circulating estrogens exist in a dynamic equilibrium of metabolic interconversions, estradiol is the principal intracellular human estrogen and is substantially more potent than its metabolites, estrone and estriol, at the receptor level. The primary source of estrogen in normally cycling adult women is the ovarian follicle, which secretes 70 to 500 mcg of estradiol daily, depending on the phase of the menstrual cycle.

After menopause, most endogenous estrogen is produced by conversion of androstenedione, secreted by the adrenal cortex, to estrone in the peripheral tissues. Thus, estrone and the sulfate-conjugated form, estrone sulfate, are the most abundant circulating estrogens in postmenopausal women. Estrogens act through binding to nuclear receptors in estrogen-responsive tissues.

To date, two estrogen receptors have been identified. These vary in proportion from tissue to tissue. Circulating estrogens modulate the pituitary secretion of the gonadotropins, luteinizing hormone (LH) and FSH through a negative feedback mechanism.

Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women.

12.2Pharmacodynamics Generally, a serum estrogen concentration does not predict an individual woman’s therapeutic response to ELESTRIN nor her risk for adverse outcomes. Likewise, exposure comparisons across different estrogen products to infer efficacy or safety for the individual woman may not be valid.

12.3Pharmacokinetics Absorption Steady-state serum concentrations of estradiol are achieved in approximately 3 days following daily application of ELESTRIN to the upper arm. Pharmacokinetic parameters for estradiol on Day 14 following daily application of 0.87 g or 1.7 g of ELESTRIN are summarized in Table 2. Dose dependent PK parameters for ELESTRIN 0.87 g and 1.7 g indicated the dose and serum estradiol (E2) concentrations to be linearly related but not dose-proportional (i.e., doubling in dose led to a 2.5- to 3.0-fold increase in PK parameters).

The nominal mean delivery rates of estradiol using the baseline-adjusted average serum concentrations from pharmacokinetic studies using 0.87 g per day and 1.7 g per day are 0.0125 mg per day and 0.0375 mg per day, respectively.

Based on the C ave values at steady state, the E2:E1 ratio was 0.53 for the 0.87 g and 0.98 for the 1.7 g doses. The significance of this finding is that the 1.7 g dose produced an E2:E1 ratio of a premenopausal woman.

The 1.7 g dose of ELESTRIN reached the goal of restoring the E2:E1 ratio (~1.0) to that observed in premenopausal women in the early follicular phase of the menstrual cycle. Application of sunscreen 10 minutes before application of ELESTRIN increased the exposure to estradiol by approximately 55 percent. No significant change in estradiol exposure was observed when sunscreen was applied 25 minutes after application of ELESTRIN.

In the same study, prolonged (7 days) concomitant application of sunscreen to the site of ELESTRIN application increased exposure to estradiol by about 2-fold, regardless of whether it was applied before or after application of ELESTRIN. elestrin-graph Distribution The distribution of exogenous estrogens is similar to that of endogenous estrogens.

Estrogens are widely distributed in the body and are generally found in higher concentrations in the sex hormone target organs. Estrogens circulate in blood largely bound to SHBG and albumin.

Metabolism Exogenous estrogens are metabolized in the same manner as endogenous estrogens. Circulating estrogens exist in a dynamic equilibrium of metabolic interconversions. These transformations take place mainly in the liver.

Estradiol is converted reversibly to estrone, and both can be converted to estriol, which is a major urinary metabolite. Estrogens also undergo enterohepatic recirculation via sulfate and glucuronide conjugation in the liver, biliary secretion of conjugates into the intestine, and hydrolysis in the intestine followed by reabsorption. In postmenopausal women, a significant proportion of the circulating estrogens exist as sulfate conjugates, especially estrone sulfate, which serves as a circulating reservoir for the formation of more active estrogens.

Excretion Estradiol, estrone and estriol are excreted in the urine along with glucuronide and sulfate conjugates. Potential for Estradiol Transfer The potential for estradiol transfer between treated postmenopausal female subjects and their untreated male partners was evaluated. Two and 8 hours after women applied 2.6 g ELESTRIN to one arm (12 women per time point), they engaged in direct arm-to-arm contact with a male partner for 5 minutes.

No significant changes in estradiol pharmacokinetic parameters were observed in the male partners after contact. Less than 10 percent of the estradiol dose was measured on the skin at 2 and 8 hours after application. After washing the application site with so… [Excerpted — this section continues on DailyMed.]

14 CLINICAL STUDIES

14.1Effects on Vasomotor Symptoms in Postmenopausal Women A randomized, double-blind, placebo-controlled clinical trial evaluated the efficacy of 12-week treatment with three different daily doses of ELESTRIN for the treatment of vasomotor symptoms in 484 postmenopausal women between 28 and 74 years of age (mean 54 years; 83-88 percent Caucasian per group) who had at least 60 moderate-to-severe hot flushes per week at baseline. At baseline, mean hot flushes is 13 per day, mean serum estradiol is 11.2-13.2 pg/mL, and prior hormone/estrogen therapy is 75.7-84.5 percent.

Participants applied placebo, 1.7 g (1.04 mg estradiol), or 2.6 g (1.56 mg estradiol) once daily to the upper arm. The study was amended to identify the lowest effective dose of ELESTRIN and limit the number of women exposed to the 2.6 g dose. After the study amendment, ELESTRIN 0.87 g (0.52 mg estradiol) was added and the 2.6 g was discontinued from further enrollment.

Reduction in both the frequency and severity of moderate to severe hot flushes was statistically significant for the ELESTRIN 1.7 g per day dose compared to placebo at week 4. Statistically significant reductions in both the frequency and severity of moderate to severe hot flushes when compared to placebo were delayed for the ELESTRIN 0.87 g per day dose to week 5. Both the 0.87 g per day and 1.7 g per day doses were statistically significant compared to placebo at week 12.

Statistically significant reductions in the frequency and severity of daily moderate-to-severe hot flush rate compared to placebo were noted beginning at week 3 for the 1.7 g per day ELESTRIN treatment (data on file). The reductions in frequency and severity are shown in Table 3.

14.2Women’s Health Initiative Studies The WHI enrolled approximately 27,000 predominantly healthy postmenopausal women in two substudies to assess the risks and benefits of daily oral CE (0.625 mg)-alone or in combination with MPA (2.5 mg) compared to placebo in the prevention of certain chronic diseases. The primary endpoint was the incidence of CHD (defined as nonfatal MI, silent MI and CHD death), with invasive breast cancer as the primary adverse outcome. A “global index” included the earliest occurrence of CHD, invasive breast cancer, stroke, PE, endometrial cancer (only in the CE plus MPA substudy), colorectal cancer, hip fracture, or death due to other cause.

These substudies did not evaluate the effects of CE-alone or CE plus MPA on menopausal symptoms. WHI Estrogen-Alone Substudy The WHI estrogen-alone substudy was stopped early because an increased risk of stroke was observed, and it was deemed that no further information would be obtained regarding the risk and benefits of estrogen-alone in predetermined endpoints. Results of the estrogen-alone substudy, which included 10,739 women (average 63 years of age, range 50 to 79; 75.3 percent White, 15.1 percent Black, 6.1 percent Hispanic, 3.6 percent Other), after an average follow-up of 7.1 years are presented in Table 4.

PATIENT INFORMATION ELESTRIN ® (el-LES-strin) (estradiol gel) Read this Patient Information before you start using ELESTRIN and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

What is the most important information I should know about ELESTRIN (an estrogen hormone)? • Using estrogen-alone increases your chance of getting cancer of the uterus (womb)Report any unusual vaginal bleeding right away while you are using ELESTRIN. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause. • Do not use estrogen-alone to prevent heart disease, heart attacks, strokes, or dementia (decline in brain function) • Using estrogen-alone may increase your chances of getting strokes or blood clots • Using estrogen-alone may increase your chance of getting dementia, based on a study of women age 65 years or older • Do not use estrogens with progestins to prevent heart disease, heart attacks, strokes or dementia • Using estrogens with progestins may increase your chances of getting heart attacks, strokes, breast cancer, or blood clots • Using estrogens with progestins may increase your chance of getting dementia, based on a study of women age 65 years or older • Only one estrogen-alone product and dose have been shown to increase your chances of getting strokes, blood clots, and dementia.

Only one estrogen with progestin product and dose have been shown to increase your chances of getting heart attacks, strokes, breast cancer, blood clots, and dementia. • Because other products and doses have not been studied in the same way, it is not known how the use of ELESTRIN will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with ELESTRIN. What is ELESTRIN?

ELESTRIN is a prescription medicine in a colorless gel that contains the estrogen hormone estradiol. When applied to the skin, estradiol is absorbed through the skin into the blood stream. What is ELESTRIN used for?

ELESTRIN is used after menopause to: • Reduce moderate to severe hot flashes Estrogens are hormones made by a woman’s ovaries. The ovaries normally stop making estrogens when a woman is between 45 to 55 years old. This drop in body estrogen levels causes the “change of life” or menopause (the end of monthly menstrual periods).

Sometimes, both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes “surgical menopause.” When estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense feelings of heat and sweating (“hot flashes” or “hot flushes”). In some women, the symptoms are mild, and they will not need estrogens.

In other women, symptoms can be more severe. You and your healthcare provider should talk regularly about whether you still need treatment with ELESTRIN. Who should not use ELESTRIN?

Do not start ELESTRIN if you: • have unusual vaginal bleeding Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause. • have been diagnosed with a bleeding disorder • currently have or have had certain cancers Estrogens may increase the chances of getting certain types of cancers, including cancer of the breast or uterus (womb). If you have or have had cancer, talk with your healthcare provider about whether you should use ELESTRIN. • had a stroke or heart attack • currently have or have had blood clots • currently have or have had liver problems • are allergic to ELESTRIN or any of its ingredients See the list of ingredients in ELESTRIN at the end of this leaflet Before you use ELESTRIN,… [Excerpted — this section continues on DailyMed.]

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
📅 Q1 2025 – Q1 2026 · 5 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

💵 About the dollar figures: “reimbursed” is what Medicaid paid pharmacies before confidential manufacturer rebates, so the program’s real net cost is lower than these numbers.

Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Elestrin — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Elestrin. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.
