Qualitative And Quantitative Composition. The active ingredient is estra- 1, 3,5(1. Pharmaceutical Form. Estraderm MX is a square- shaped, self- adhesive, transparent, transdermal patch for application to the skin surface. Each patch comprises an impermeable polyester backing film, an adhesive matrix containing estradiol and an oversized protective liner which is removed prior to application of the patch to the skin. Estraderm MX releases estradiol into the circulation via intact skin at a low rate for up to 4 days. Clinical Particulars. Therapeutic Indications. Hormone replacement therapy (HRT) for estrogen deficiency symptoms in postmenopausal women. Withdrawal bleeding usually occurs following 1. Unless there is a previous diagnosis of endometriosis, it is not recommended to add a progestagen in hysterectomised women. Depending on the clinical response the dose can then be adjusted to the patient's individual needs. If, after three months, there is insufficient response in the form of alleviated symptoms, the dose can be increased. A maximum dose of 1. However, if symptoms persist for more than six weeks the dose should be reduced. However, for women with an intact uterus who are still menstruating regularly, commencement within 5 days of the onset of bleeding is recommended. The site chosen should be one at which little wrinkling of skin occurs during movement of the body, e. Estraderm MX should never be applied to, or near the breasts. The subsequent patch should be applied according to the original treatment schedule. The interruption of treatment might increase the likelihood of recurrence of symptoms and include breakthrough spotting and bleeding. The original treatment schedule should be continued. In all cases, a careful appraisal of the risks and benefits should be undertaken at least annually and HRT should only be continued as long as the benefit outweighs the risk. Physical (including pelvic and breast) examination should be guided by this and by the contraindications and warnings for use. During treatment, periodic check- ups are recommended of a frequency and nature adapted to the individual woman. Women should be advised what changes in their breasts should be reported to their doctor or nurse (see 'Breast cancer' below). Investigations, including mammography, should be carried out in accordance with currently accepted screening practices, modified to the clinical needs of the individual. It should be taken into account that these conditions may recur or be aggravated during treatment with Estraderm MX, in particular. The addition of a progestagen for at least 1. Withdrawal bleeding usually occurs following the 1. Break- through bleeding and spotting may occur during the first months of treatment. If break- through bleeding or spotting appears after some time on therapy, or continues after treatment has been discontinued, the reason should be investigated, which may include endometrial biopsy to exclude endometrial malignancy. Therefore, the addition of progestagens to estrogen replacement therapy should be considered in women who have undergone hysterectomy because of endometriosis, if they are known to have residual endometriosis. There was no evidence of a difference in risk between the different routes of administration. For non- users, it is estimated that the number of cases of VTE that will occur over a 5 year period is about 3 per 1. It is estimated that in healthy women who use HRT for 5 years, the number of additional cases of VTE over a 5 year period will be between 2 and 6 (best estimate = 4) per 1. The occurrence of such an event is more likely in the first year of HRT than later. There is no consensus about the role of varicose veins in VTE. HRT may add to this risk. Personal or strong family history of thromboembolism or recurrent spontaneous abortion should be investigated in order to exclude a thrombophilic predisposition. Until a thorough evaluation of thrombophilic factors has been made or anticoagulant treatment initiated, use of HRT in such patients should be viewed as contra- indicated. Those women already on anticoagulant treatment require careful consideration of the benefit- risk of use of HRT. As in all post- operative patients scrupulous attention should be given to prophylactic measures to prevent VTE following surgery. Where prolonged immobilisation is liable to follow elective surgery, particularly abdominal or orthopaedic surgery to the lower limbs, consideration should be given to temporarily stopping HRT four to six weeks earlier, if possible. Treatment should not be restarted until the woman is completely mobilised. Patients should be told to contact their doctors immediately when they are aware of a potential thromboembolic symptom (e. Large clinical trials showed a possible increased risk of cardiovascular morbidity in the first year of use and no overall benefit. For other HRT products there only limited data from randomised controlled trials examining effect on cardiovascular morbidity or mortality. Therefore, it is uncertain whether these findings also extend to other HRT products. For women who do not use HRT, it is estimated that the number of cases of stroke that will occur over a 5 year period is about 3 per 1. It is estimated that for women who use conjugated estrogens and MPA for 5 years, the number of additional cases will be between 0 and 3 (best estimate = 1) per 1. It is unknown whether the increased risk also extends to other HRT products. It is uncertain whether long- term use of combined HRT confers a different risk than estrogen- only products. Patients with terminal renal insufficiency should be closely observed, since it is expected that the level of circulating active ingredients in Estraderm MX is increased. T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Other binding proteins may be elevated in serum, i. Free or biological active hormone concentrations are unchanged. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha- I- antitrypsin, ceruloplasmin). These effects may be less common with transdermal estradiol than with oral estrogens. Although it is extremely rare, patients who develop contact sensitisation to any of the components of the patch should be warned that a severe hypersensitivity reaction may occur with continuous exposure to the causative agent. Women requiring contraception should be advised to use non- hormonal contraception. There is some evidence from the WHI trial of increased risk of probable dementia in women who start using continuous combined CEE and MPA after the age of 6. It is unknown whether the findings apply to younger postmenopausal women or other HRT products. If pregnancy occurs during medication with Estraderm MX treatment should be withdrawn immediately. Med. DRA SOC level). Common ADRS. Uncommon ADRs. Rare ADRs. Central nervous system. Headache. According to data from epidemiological studies, the best estimate of the risk of endometrial cancer is that for women not using HRT, about 5 in every 1. Depending on the duration of treatment and estrogen dose, the reported increase in endometrial cancer risk among unopposed estrogen users varies from 2- to 1. Adding a progestagen to estrogen- only therapy greatly reduces this increased risk. For further information, see section 4. Contraindications and 4. Special warnings and precautions for use. Pharmacological Properties. Pharmacodynamic Properties. Pharmacotherapeutic group: estrogens ATC code G 0. C A 0. 3. It substitutes for the loss of estrogen production in menopausal women, and alleviates menopausal symptoms. Estrogen deficiency at menopause is associated with an increasing bone turnover and decline in bone mass. The effect of estrogens on the bone mineral density is dose- dependent. Estraderm MX 1. 00 is not recommended as the risk/benefit of the higher dose in osteoporosis has not been assessed in clinical studies. However, it may be used if necessary to control concurrent menopausal symptoms. After discontinuation of HRT, bone mass is lost at a rate similar to that in untreated women. HRT may also prevent fractures in women with low bone density and/or established osteoporosis, but the evidence for that is limited. The mean E2 concentration during steady- state of Estraderm MX 5. L in healthy postmenopausal women, corresponding to a mean increase of 3. L over the mean baseline value of 4 pg/m. L (range 2. 1 to 9. L). The E2: E1 ratio increases from a postmenopausal value of 0. E2 to E1 observed before the menopause in women with normally functioning ovaries. During continuous treatment of postmenopausal women with Estraderm MX 5. E2 plasma concentrations rise by 3. L above baseline at the end of the treatment phase, without any indication that accumulation of E2 levels occurs . Only a fraction is free and biologically active . Oestradiol is metabolised to oestrone, then later – primarily in the liver – to oestriol, epioestriol and catechol oestrogens, which are then conjugated to sulphates and glucoronides. Cytochrome 4. 50 isoforms CYP1. A2 and CYP3. A4 catalyse the hydroxylation of oestradiol forming oestriol. Oestriol is glucuronidated by UGT1. A1 and UGT2. B7 in humans. Metabolic plasma clearance ranges from 6. L/(day x m?). Oestradiol metabolites are also subject to enterohepatic circulation. Oestradiol metabolites are far less active than oestradiol. The plasma elimination half- life of oestradiol is about 1 hour. Oestradiol conjugates excreted in the urine return to pre- application levels on the second or third day after removal of the system. Because of marked differences between animal species and between animals and humans, preclinical results possess a limited predictive value for the application of estrogens in humans.
