DOTTI Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.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 may result in adverse reactions. Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentration. ( 7 )
Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism 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, 2 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 follicle stimulating hormone (FSH) through a negative feedback mechanism. Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women. 12.2 Pharmacodynamics Generally, a serum estrogen concentration does not predict an individual woman’s therapeutic response to DOTTI 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. 12.3 Pharmacokinetics Absorption In a multiple-dose study consisting of 3 consecutive system applications of the original formulation of estradiol transdermal system which was conducted in 17 healthy, postmenopausal women, blood levels of estradiol and estrone were compared following application of these units to sites on the abdomen and buttocks in a crossover fashion. Systems that deliver nominal estradiol doses of approximately 0.0375 mg per day and 0.1 mg per day were applied to abdominal application sites while the 0.1 mg per day doses were also applied to sites on the buttocks. These systems increased estradiol levels above baseline within 4 hours and maintained respective mean levels of 25 and 79 pg/mL above baseline following application to the abdomen; slightly higher mean levels of 88 pg/mL above baseline were observed following application to the buttocks. At the same time, increases in estrone plasma concentrations averaged about 12 and 50 pg/mL, respectively, following application to the abdomen and 61 pg/mL for the buttocks. While plasma concentrations of estradiol and estrone remained slightly above baseline at 12 hours following removal of the systems in this study, results from another study show these levels to return to baseline values within 24 hours following removal of the systems. Figure 1 illustrates the mean plasma concentrations of estradiol at steady-state during application of these patches at 4 different dosages. Figure 1. Steady-State Estradiol Plasma Concentrations for Systems Applied to the Abdomen Nonbaseline-corrected Levels The corresponding pharmacokinetic parameters are summarized in Table 2. Table 2. Steady-State Estradiol Pharmacokinetic Parameters for Systems Applied to the Abdomen (mean ± standard deviation) Nonbaseline-corrected Data* Dosage (mg/day) C max † (pg/mL) C avg ‡ (pg/mL) C min (84 hr) § (pg/mL) 0.0375 46 ± 16 34 ± 10 30 ±10 0.05 83 ± 41 57 ± 23 # 41 ± 11 # 0.075 99 ± 35 72 ± 24 60 ± 24 0.1 133 ± 51 89 ± 38 90 ± 44 0.1 ¶ 145 ± 71 104 ± 52 85 ± 47 *Mean baseline estradiol concentration =11.7 pg/mL. † Peak plasma concentration. ‡ Average plasma concentration. § Minimum plasma concentration at 84 hr. # Measured over 80 hr. ¶ Applied to the buttocks. DOTTI (estradiol transdermal system), the revised formulation with smaller system sizes, was shown to be bioequivalent to the original formulation of estradiol transdermal system, used in the clinical trials. 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 the blood largely bound to sex hormone-binding globulin (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 by Cytochrome 450 isoforms CYP1A2 and CYP3A4. Estradiol undergoes further metabolism to sulfate and glucuronide conjugates. Estradiol and its metabolites are glucuronidated by UGT1A1 and UGT2B7. 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 portion 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. The half-life values calculated after dosing with DOTTI ranged from 5.9 to 7.7 hours. After removal of the transdermal systems, serum concentrations of estradiol and estrone returned to baseline levels within 24 hours. Adhesion Based on combined data from 3 short-term clinical trials consisting of 471 observations, 85% of DOTTI adhered completely to the skin over the 3.5-day wear period. Three percent (3%) of the systems detached and were reapplied or replaced during the 3.5-day wear period. Approximately 80% of the transdermal systems evaluated in these studies were DOTTI 0.05 mg per day. Figure 1

FDA approved acceptance criteria for dissolution test specifications differ from USP. 1 2
Dosage and administration
Information about the drug product’s dosage and administration recommendations, including starting dose, dose range, titration regimens, and any other clinically sigificant information that affects dosing recommendations.2 DOSAGE AND ADMINISTRATION Generally, when estrogen is prescribed for a postmenopausal woman with a uterus, consider addition of a progestogen to reduce the risk of endometrial cancer. Generally, a woman without a uterus does not need to use a progestogen in addition to her estrogen therapy. In some cases, however, hysterectomized women who have a history of endometriosis may need a progestogen [see Warnings and Precautions (5.2 , 5.14) ] . Use estrogen-alone or in combination with a progestogen at the lowest effective dose and the shortest duration consistent with treatment goals and risks for the individual woman. Reevaluate postmenopausal women periodically as clinically appropriate to determine whether treatment is still necessary. Start therapy with DOTTI 0.0375 mg/day applied to the skin twice weekly for the treatment of moderate to severe vasomotor symptoms due to menopause or moderate to severe symptoms of vulvar and vaginal atrophy symptoms due to menopause. Dosage adjustment should be guided by the clinical response (2.1 , 2.2 , 2.3) Start therapy with DOTTI 0.025 mg/day for the prevention of postmenopausal osteoporosis (2.4) Place DOTTI on a clean, dry area of the lower abdomen or buttocks. Do not apply DOTTI to the breasts (2.5) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause Start therapy with DOTTI 0.0375 mg per day applied to the skin twice weekly. Make dosage adjustments based on the clinical response. Initiate DOTTI at once in a woman not currently taking oral estrogens or in a woman switching from another estradiol transdermal therapy. In women who are currently taking oral estrogens, initiate treatment with DOTTI 1 week after withdrawal of oral hormone therapy, or sooner if menopausal symptoms reappear in less than 1 week. Attempts to taper or discontinue DOTTI at 3 to 6 month intervals. Give DOTTI continuously in a woman who does not have an intact uterus. In a woman with an intact uterus, give DOTTI on a cyclic schedule (for example, 3 weeks on DOTTI followed by 1 week off DOTTI). 2.2 Treatment of Moderate to Severe Symptoms of Vulvar and Vaginal Atrophy due to Menopause Start therapy with DOTTI 0.0375 mg per day applied to the skin twice weekly. Dosage adjustment should be guided by the clinical response. Attempts to taper or discontinue DOTTI at 3 to 6 month intervals. In women not currently taking oral estrogens or in women switching from another estradiol transdermal therapy, treatment with DOTTI may be initiated at once. In women who are currently taking oral estrogens, initiate treatment with DOTTI 1 week after withdrawal of oral hormone therapy, or sooner if menopausal symptoms reappear in less than 1 week. Give DOTTI continuously in a woman who does not have an intact uterus. In a woman with an intact uterus, give DOTTI on a cyclic schedule (for example, 3 weeks on DOTTI followed by 1 week off DOTTI). 2.3 Hypoestrogenism Due to Hypogonadism, Castration, or Primary Ovarian Failure 2.4 Prevention of Postmenopausal Osteoporosis Start therapy with DOTTI 0.025 mg per day applied to the skin twice weekly. In women not currently taking oral estrogens or in women switching from another estradiol transdermal therapy, treatment with DOTTI may be initiated at once. In women who are currently taking oral estrogens, initiate treatment with DOTTI 1 week after withdrawal of oral hormone therapy, or sooner if menopausal symptoms reappear in less than 1 week. DOTTI may be given continuously in a woman who does not have an intact uterus. In a woman with an intact uterus, DOTTI may be given on a cyclic schedule (for example, 3 weeks on DOTTI followed by 1 week off DOTTI). 2.5 Application Instructions Place the adhesive side of DOTTI on a clean, dry area of the trunk of the body (including the abdomen or buttocks). Do not apply DOTTI to the breasts. Replace DOTTI twice weekly. Rotate the sites of application, with an interval of at least 1 week allowed between applications to a particular site. Select an area that is not oily, damaged, or irritated. Avoid the waistline, since tight clothing may rub the system off. Apply the system immediately after opening the pouch and removing the protective liner. Press the system firmly in place with the palm of the hand for about 10 seconds, making sure there is good contact, especially around the edges. In the event that a system falls off, reapply the same system or apply a new system to another location. In either case, continue the original treatment schedule. If a woman has forgotten to apply DOTTI, have her apply a new system as soon as possible. Apply the new system on the original treatment schedule. The interruption of treatment in women taking DOTTI might increase the likelihood of breakthrough bleeding, spotting and recurrence of symptoms.

Instructions for use
Information about safe handling and use of the drug product.INSTRUCTIONS FOR USE DOTTI (dah ʹ tee) (estradiol transdermal system) Read this Instructions for Use before you start using DOTTI 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 menopausal symptoms or your treatment. 1. Determine Your Schedule for Your Twice-a-Week Application Decide upon which 2 days you will change your patch. Your DOTTI (estradiol transdermal system) individual carton contains a calendar card printed on its inner flap. Mark the 2-day schedule you plan to follow on your carton’s inner flap. Be consistent. If you forget to change your patch on the correct date, apply a new one as soon as you remember. No matter what day this happens, stick to the schedule you have marked on the inner flap of your carton (your calendar card). 2. Where to Apply DOTTI Apply patch to a dry area of the skin of the trunk of the body, including the lower abdomen, or buttocks. Avoid the waistline, since clothing may cause the patch to rub off. Do not apply patch to breasts. When changing your patch, based on your twice-a-week schedule, apply your new patch to a different site. Do not apply a new patch to that same area for at least 1 week. 3. Before You Apply DOTTI Make sure your skin is: Clean (freshly washed), dry and cool. Free of any powder, oil, moisturizer or lotion. Free of cuts or irritations (rashes or other skin problems). 4. How to Apply DOTTI Each patch is individually sealed in a protective pouch. Tear open the pouch at the tear notch (do not use scissors). Remove the patch. Apply the patch immediately after removing from the pouch. Holding the patch with the rigid protective liner facing you, remove half of the liner, which covers the sticky surface of the patch. Avoid touching the sticky side of the patch with your fingers. Using the other half of the rigid protective liner as a handle, apply the sticky side of the patch to the selected area of the abdomen or buttocks. Press the sticky side of the patch firmly into place. Smooth it down. While still holding the sticky side down, fold back the other half of the patch. Grasp an edge of the remaining protective liner and gently pull it off. Avoid touching the sticky side of the patch with your fingers. Press the entire patch firmly into place with the palm of your hand. Continue to apply pressure, with the palm of your hand over the patch, for approximately 10 seconds. Make sure that the patch is properly adhered to your skin. Go over the edges with your finger to ensure good contact around the patch. Note: Showering will not cause your patch to fall off. If your patch falls off reapply it. If you cannot reapply the patch, apply a new patch to another area and continue to follow your original placement schedule. If you stop using your DOTTI patch or forget to apply a new patch as scheduled, you may have spotting, or bleeding, and recurrence of symptoms. 5. Throwing Away Your Used Patch When it is time to change your patch, remove the old patch before you apply a new patch. To throw away the patch, fold the sticky side of the patch together, place it in a sturdy child-proof container, and place the container in the trash. Used patches should not be flushed in the toilet. This Patient Information and Instructions for Use have been approved by the U.S. Food and Drug Administration.

Patient medication information
Information or instructions to patients about safe use of the drug product, sometimes including a reference to a patient medication guide or counseling materials.PATIENT INFORMATION DOTTI (dah ʹ tee) ( estradiol transdermal system) Read this Patient Information before you start using DOTTI 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 menopausal symptoms or your treatment. What is the most important information I should know about DOTTI (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 DOTTI. 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 65 years of age and older. Do not use estrogens with progestogens to prevent heart disease, heart attacks, strokes, or dementia. Using estrogens with progestogens may increase your chances of getting heart attacks, strokes, breast cancer, or blood clots. Using estrogens with progestogens may increase your chance of getting dementia, based on a study of women 65 years of age and 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 progestogen 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 DOTTI will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with DOTTI. What is DOTTI? DOTTI is a prescription medicine patch (transdermal system) that contains the estrogen hormone estradiol. When applied to the skin, estradiol is absorbed through the skin into the bloodstream. What is DOTTI used for? DOTTI 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 and 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 to use estrogens. In other women, symptoms can be more severe. Treat moderate to severe menopausal changes in and around the vagina You and your healthcare provider should talk regularly about whether you still need treatment with DOTTI to control these problems. If you use DOTTI only to treat your menopausal changes in and around your vagina, talk with your healthcare provider about whether a topical vaginal product would be better for you. Treat certain conditions in women before menopause if their ovaries do not produce enough estrogens naturally Help reduce your chances of getting osteoporosis (thin weak bones) Osteoporosis from menopause is a thinning of the bones that makes them weaker and easier to break. If you use DOTTI to prevent osteoporosis due to menopause, talk with your healthcare provider about whether a different treatment or medicine without estrogens might be better for you. You and your healthcare provider should talk regularly about whether you should continue treatment with DOTTI. Who should not use DOTTI? Do not start using DOTTI 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 DOTTI. had a stroke or heart attack currently have or have had blood clots currently have or have had liver problems are allergic to DOTTI or any of the ingredients in it See the list of ingredients in DOTTI at the end of this leaflet. Before you use DOTTI, tell your healthcare provider about all of your medical conditions, including if you: have any 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 any other medical conditions that may become worse while you are using DOTTI Your healthcare provider may need to check you more carefully if you have certain conditions such as asthma (wheezing), epilepsy (seizures), diabetes, migraine, endometriosis, lupus, angioedema (swelling of face and tongue); problems with your heart, liver, thyroid, kidneys, or have high calcium levels in your blood. are going to have surgery or will be on bed rest Your healthcare provider will let you know if you need to stop using DOTTI. are pregnant or think you may be pregnant. DOTTI is not for pregnant women. are breastfeeding The hormone in DOTTI can pass into your breast milk. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Some medicines may affect how DOTTI works. DOTTI may also affect how your other medicines work. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get new medicine. How should I use DOTTI? For detailed instructions, see the step-by-step instructions for using DOTTI at the end of this Patient Information. Use DOTTI exactly as your healthcare provider tells you to use it. DOTTI is for skin use only. Change your DOTTI patch 2 times a week or every 3 to 4 days. Apply your DOTTI patch to a clean, dry area on your lower abdomen. This area must be clean, dry, and free of powder, oil or lotion for your patch to stick to your skin. Apply your DOTTI patch to a different area of your abdomen each time. Do not use the same application site 2 times in the same week. Do not apply DOTTI to your breasts. If you forget to apply a new DOTTI patch, apply a new patch as soon as possible. You and your healthcare provider should talk regularly (every 3 to 6 months) about your dose and whether you still need treatment with DOTTI. How to change DOTTI When changing the patch, peel off the used patch slowly from the skin. After removal of DOTTI if any adhesive residue remains on your skin, allow the area to dry for 15 minutes. Then, gently rub the area with oil or lotion to remove the adhesive from your skin. Apply the new patch to a different area of your lower abdomen. This area must be clean, dry, cool and free of powder, oil, or lotion. What are the possible side effects of DOTTI? Side effects are grouped by how serious they are and how often they happen when you are treated. Serious, but less common side effects include: heart attack high blood pressure stroke high levels of fat (triglyceride) in your blood blood clots liver problems breast cancer changes in your thyroid hormone levels cancer of the lining of the uterus (womb) fluid retention cancer of the ovary cancer changes of endometriosis dementia enlargement of benign tumors of the uterus (“fibroids”) high or low blood calcium worsening of swelling of face and tongue (angioedema) in women with a history of angioedema gallbladder disease visual abnormalities Call your healthcare provider right away if you get any of the following warning signs or any other unusual symptoms that concern you: new breast lumps unusual vaginal bleeding changes in vision or speech sudden new severe headaches severe pains in your chest or legs with or without shortness of breath, weakness and fatigue swelling of face and tongue with or without red, itchy bumps Common side effects of DOTTI include: headache nausea and vomiting breast pain hair loss irregular vaginal bleeding or spotting fluid retention painful periods vaginal yeast infection stomach or abdominal cramps, bloating redness and/or irritation at patch placement site These are not all the possible side effects of DOTTI. For more information, ask your healthcare provider or pharmacist. Tell your healthcare provider if you have any side effects that bother you or do not go away. You may report side effects to FDA at 1-800-FDA-1088. You may report side effects to Amneal Pharmaceuticals (1-877-835-5472). What can I do to lower my chances of getting a serious side effect with DOTTI? Talk with your healthcare provider regularly about whether you should continue using DOTTI. If you have a uterus, talk to your healthcare provider about whether the addition of a progestogen is right for you. In general, the addition of a progestogen is recommended for a woman with a uterus to reduce the chance of getting cancer of the uterus (womb). See your healthcare provider right away if you get vaginal bleeding while using DOTTI. Have a pelvic exam, breast exam and mammogram (breast X-ray) every year unless your healthcare provider tells you something else. If members of your family have had breast cancer or if you have ever had breast lumps or an abnormal mammogram, you may need to have breast exams more often. If you have high blood pressure, high cholesterol (fat in the blood), diabetes, are overweight, or if you use tobacco, you may have higher chances for getting heart disease. Ask your healthcare provider for ways to lower your chances for getting heart disease. How should I store and throw away used DOTTI patches? Store DOTTI at room temperature 68° to 77°F (20° to 25°C) Do not store DOTTI patches outside of their pouches. Apply immediately upon removal from the protective pouch. Used patches still contain estrogen. To throw away the patch, fold the sticky side of the patch together, place it in a sturdy child-proof container, and place this container in the trash. Used patches should not be flushed in the toilet. Keep DOTTI and all medicines out of the reach of children. General information about safe and effective use of DOTTI Medicines are sometimes prescribed for purposes other than those listed in Patient Information leaflets. Do not use DOTTI for conditions for which it was not prescribed. Do not give DOTTI to other people, even if they have the same symptoms you have. It may harm them. You can ask your healthcare provider or pharmacist for information about DOTTI that is written for health professionals.

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES 14.1 Effects on Vasomotor Symptoms in Postmenopausal Women In a pharmacokinetic study, DOTTI was shown to be bioequivalent to the original estradiol formulation. In 2 controlled clinical trials with the original estradiol formulation, of 356 women, the 0.075 and 0.1 mg doses were superior to placebo in relieving vasomotor symptoms at Week 4, and maintained efficacy through Weeks 8 and 12 of treatment. In this original study, the 0.0375 and 0.05 mg doses, however, did not differ from placebo until approximately Week 6, therefore, an additional 12-week, placebo-controlled study in 255 women was performed with the original estradiol formulation to establish the efficacy of the lowest dose of 0.0375 mg. The baseline mean daily number of hot flushes in these 255 women was 11.5. Results at Weeks 4, 8, and 12 of treatment are shown in Figure 2. Figure 2. Mean (SD) Change from Baseline in Mean Daily Number of Flushes for Estradiol 0.0375 mg Versus Placebo in a 12-week Trial The 0.0375 mg dose was superior to placebo in reducing both the frequency and severity of vasomotor symptoms at Week 4 and maintained efficacy through Weeks 8 and 12 of treatment. All doses of the original estradiol formulation (0.0375 mg, 0.05 mg, 0.075 mg, and 0.1 mg) are effective for the control of vasomotor symptoms. 2 14.2 Effects on Bone Mineral Density in Postmenopausal Women Efficacy and safety of the original estradiol formulation in the prevention of postmenopausal osteoporosis have been studied in a 2-year, double-blind, randomized, placebo-controlled, parallel-group study. A total of 261 hysterectomized (161) and non-hysterectomized (100), surgically or naturally menopausal women (within 5 years of menopause), with no evidence of osteoporosis (lumbar spine bone mineral density within 2 standard deviations of average peak bone mass, i.e., at least 0.827 g/cm 2 ) were enrolled in this study; 194 women were randomized to 1 of the 4 doses of the original estradiol formulation (0.1, 0.05, 0.0375, or 0.025 mg/day) and 67 patients to placebo. Over 2 years, study systems were applied to the buttock or the abdomen twice a week. Non-hysterectomized women received oral medroxyprogesterone acetate (2.5 mg/day) throughout the study. The study population comprised naturally (82%) or surgically (18%) menopausal, hysterectomized (61%) or non-hysterectomized (39%) women with a mean age of 52 years (range 27 to 62 years); the mean duration of menopause was 31.7 months (range 2 to 72 months). Two hundred thirty-two (89%) of randomized women (173 on active drug, 59 on placebo) contributed data to the analysis of percent change from baseline in bone mineral density (BMD) of the AP lumbar spine, the primary efficacy variable. Women were given supplemental dietary calcium (1000 mg elemental calcium/day) but no supplemental vitamin D. There was an increase in BMD of the AP lumbar spine in all the original estradiol formulation dose groups; in contrast to this, a decrease in AP lumbar spine BMD was observed in placebo patients. All estradiol doses were significantly superior to placebo (p<0.05) at all time points with the exception of estradiol 0.05 mg/day at 6 months. The highest dose of estradiol was superior to the 3 lower doses. There were no statistically significant differences in pairwise comparisons among the 3 lower doses (See Figure 3). Figure 3. Bone Mineral Density-AP Lumbar Spine Least Squares Means of Percentage Change from Baseline All Randomized Patients with at Least One Post-baseline Assessment Available with Last Post-baseline Observation Carried Forward Analysis of percent change from baseline in femoral neck BMD, a secondary efficacy outcome variable, showed qualitatively similar results; all doses of the original estradiol formulation were significantly superior to placebo (p<0.05) at 24 months. The highest estradiol dose was superior to placebo at all time points. A mixture of significant and nonsignificant results were obtained for the lower dose groups at earlier time points. The highest estradiol dose was superior to the 3 lower doses, and there were no significant differences among the 3 lower doses at this skeletal site (See Figure 4). Figure 4. Bone Mineral Density-Femoral Neck Least Squares Means of Percentage Change from Baseline All Randomized Patients with at Least One Post-baseline Assessment Available with Last Post-baseline Observation Carried Forward The mean serum osteocalcin (a marker of bone formation) and urinary excretion of cross-link N-telopeptides of Type 1 collagen (a marker of bone resorption) decreased numerically in most of the active treatment groups relative to baseline. However, the decreases in both markers were inconsistent across treatment groups and the differences between active treatment groups and placebo were not statistically significant. 2 1 14.3 Women’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 the 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 causes. 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 risks and benefits of estrogen-alone in predetermined primary endpoints. Results of the estrogen-alone substudy, which included 10,739 women (average 63 years of age, range 50 to 79; 75.3% White, 15.1% Black, 6.1% Hispanic, 3.6% Other) after an average follow-up of 7.1 years, are presented in Table 3.

For those outcomes included in the WHI “global index” that reached statistical significance, the absolute excess risk per 10,000 women-years in the group treated with CE-alone was 12 more strokes, while the absolute risk reduction per 10,000 women-years was 7 fewer hip fractures. 9 The absolute excess risk of events included in the “global index” was a nonsignificant 5 events per 10,000 women-years. There was no difference between the groups in terms of all-cause mortality. No overall difference for primary CHD events (nonfatal MI, silent MI and CHD death) and invasive breast cancer incidence in women receiving CE-alone compared with placebo was reported in final centrally adjudicated results from the estrogen-alone substudy, after an average follow-up of 7.1 years (See Table 3). Centrally adjudicated results for stroke events from the estrogen-alone substudy, after an average follow-up of 7.1 years, reported no significant differences in distribution of stroke subtype or severity, including fatal strokes, in women receiving CE-alone compared to placebo. Estrogen-alone increased the risk for ischemic stroke, and this excess risk was present in all subgroups of women examined 10 (See Table 3). Timing of the initiation of estrogen-alone therapy relative to the start of menopause may affect the overall risk benefit profile. The WHI estrogen-alone substudy stratified by age showed in women 50 to 59 years of age a nonsignificant trend toward reduced risk for CHD [hazard ratio (HR) 0.63 (95% CI, 0.36 to 1.09)] and overall mortality [HR 0.71 (95% CI, 0.46 to 1.11)]. WHI Estrogen Plus Progestin Substudy The WHI estrogen plus progestin substudy was stopped early. According to the predefined stopping rule, after an average follow-up of 5.6 years of treatment, the increased risk of invasive breast cancer and cardiovascular events exceeded the specified benefits included in the “global index”. The absolute excess risk of events included in the “global index” was 19 per 10,000 women-years. For those outcomes included in the WHI “global index” that reached statistical significance after 5.6 years of follow-up, the absolute excess risks per 10,000 women-years in the group treated with CE plus MPA were 7 more CHD events, 8 more strokes, 10 more PEs, and 8 more invasive breast cancers, while the absolute risk reduction per 10,000 women-years were 6 fewer colorectal cancers and 5 fewer hip fractures. Results of the CE plus MPA substudy, which included 16,608 women (average 63 years of age, range 50 to 79, 83.9% White, 6.8% Black, 5.4% Hispanic, 3.9% Other) are presented in Table 4. These results reflect centrally adjudicated data after an average follow-up of 5.6 years. Table 4.

Timing of the initiation of estrogen plus progestin therapy relative to the start of menopause may affect the overall risk benefit profile. The WHI estrogen plus progestin substudy stratified by age showed in women 50 to 59 years of age a non-significant trend toward reduced risk for overall mortality [HR 0.69 (95% CI, 0.44 to 1.07)]. 14.4 Women’s Health Initiative Memory Study The WHIMS estrogen-alone ancillary study of WHI enrolled 2,947 predominantly healthy hysterectomized postmenopausal women 65 to 79 years of age and older (45% were age 65 to 69 years of age; 36% were 70 to 74 years of age; 19% were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg)-alone on the incidence of probable dementia (primary outcome) compared to placebo. After an average follow-up of 5.2 years, the relative risk of probable dementia for CE-alone versus placebo was 1.49 (95% CI, 0.83 to 2.66). The absolute risk of probable dementia for CE-alone versus placebo was 37 versus 25 cases per 10,000 women-years. Probable dementia as defined in this study included Alzheimer’s disease (AD), vascular dementia (VaD), and mixed types (having features of both AD and VaD). The most common classification of probable dementia in the treatment group and the placebo group was AD. Since the ancillary study was conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.3) and Use in Specific Populations (8.5) ] . The WHIMS estrogen plus progestin ancillary study enrolled 4,532 predominantly healthy postmenopausal women 65 years of age and older (47% were age 65 to 69 years of age; 35% were 70 to 74 years of age; 18% were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg) plus MPA (2.5 mg) on the incidence of probable dementia (primary outcome) compared to placebo. After an average follow-up of 4 years, the relative risk of probable dementia for CE plus MPA was 2.05 (95% CI, 1.21 to 3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 per 10,000 women-years. Probable dementia as defined in this study included AD, VaD, and mixed type (having features of both AD and VaD). The most common classification of probable dementia in the treatment group and the placebo group was AD. Since the ancillary study was conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.3) and Use in Specific Populations (8.5) ] . When data from the two populations were pooled as planned in the WHIMS protocol, the reported overall relative risk for probable dementia was 1.76 (95% CI, 1.19 to 2.60). Differences between groups became apparent in the first year of treatment. It is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.3) and Use in Specific Populations (8.5) ] .

Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing DOTTI to determine whether those over 65 years of age differ from younger subjects in their response to DOTTI. The Women’s Health Initiative Studies 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 Warnings and Precautions (5.1) , and Clinical Studies (14.3) ] . 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 Warnings and Precautions (5.1) , and Clinical Studies (14.3) ] . 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 (14.4) ] . 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 (14.4) ] .
Nursing mothers
Information about excretion of the drug in human milk and effects on the nursing infant, including pertinent adverse effects observed in animal offspring.8.2 Lactation 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 breastfeeding should be considered along with the mother’s clinical need for DOTTI and any potential adverse effects on the breastfed child from DOTTI or from the underlying maternal condition.
Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use DOTTI is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population. If estrogen is administered to patients whose bone growth is not complete, periodic monitoring of bone maturation and effects on epiphyseal centers is recommended during estrogen administration.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Risk Summary DOTTI is not indicated for use in pregnancy. There are no data with the use of DOTTI in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to combined hormonal contraceptives (estrogen and progestins) before conception or during early pregnancy. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary DOTTI is not indicated for use in pregnancy.

Boxed warning
Information about contraindications or serious warnings, particularly those that may lead to death or serious injury.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 progestogen to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Perform a dequate 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 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 (14.3) ] . 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 and 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 (14.4) ] . 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 (14.3 , 14.4) ] . 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 e strogens with or without progestogens 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 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 (14.3) ] . 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 and 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 (14.4) ] . Do not use estrogen plus progestogen therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1 , 5.3) , and Clinical Studies (14.3 , 14.4) ] . 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 (14.3) ] . Only daily oral 0.625 mg CE and 2.5 mg MPA were studied in the estrogen plus progestin substudy of the 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 progestogen 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 plus progestogen therapy, taking into account her individual risk profile. Prescribe e strogens with or without progestogens at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.
