Raloxifene
Antiresorptive treatments for postmenopausal osteoporosis have been studied extensively, but due to the volume of published data and lack of head-to-head trials, it is difficult to evaluate and compare their fracture reduction efficacy. The objective of this review is to summarize the results from clinical trials that have fracture as an endpoint and to discuss the factors in study design and populations that can affect the interpretation of the results. Although there are numerous observational studies suggesting that estrogen and hormone replacement therapies may reduce the risk of vertebral and nonvertebral fractures, there is no large, prospective, randomized, placebo-controlled, double-blind clinical trial demonstrating fracture efficacy. The effects of raloxifene, alendronate, risedronate, and salmon calcitonin on increasing bone mineral density BMD ; and decreasing fracture risk have been shown in randomized, placebo-controlled, doubleblind clinical trials of postmenopausal women with osteoporosis. Although the increases in lumbar spine BMD vary greatly in these trials, the decrease in relative risk of vertebral fractures is similar among therapies. However, nonvertebral fracture efficacy has not been consistently demonstrated. Combined administration of two antiresorptive therapies results in greater BMD increases, but the effects on fracture risk are unknown. Direct comparisons of clinical trial results should be considered carefully, given the differences in study design and populations. Differences in study design that may influence the efficacy of fracture risk reduction include calcium and vitamin D supplementation, primary fracture endpoints, definition of vertebral deformity or fracture, discontinuation rates, and statistical power. Factors in the study population that may influence fracture efficacy include the age of the population and the proportion of subjects with prevalent fractures. The use of surrogate endpoints such as BMD to predict fracture risk should be approached with caution, as the relationship between BMD changes and fracture risk reduction with antiresorptive therapies is uncertain. Consideration of these results from clinical trials can contribute to clinical judgment in selecting the best treatment option for postmenopausal osteoporosis. Endocrine Reviews 23: 16 37.

A lack of endometrial proliferation, 33 even after 1 year of use.34 Advantages of the ring include not only uniform sustained and local release of low doses of estradiol as compared to doses delivered intermittently with local CEE cream ; , but also ease of insertion and improved compliance. Nachtigall et al. found the estradiol ring to be equally effective but more acceptable when compared to CEE vaginal cream for treatment of urogenital estrogen deficiency.33 However, women with limited vaginal capacity or limited manual dexterity may not be able to insert and remove the ring easily, and in women with pelvic organ prolapse, repetitive dislodgement of the ring may occur. Its 3-month duration of action makes feasible the insertion and removal of the ring by a health-care professional. Though uncommon, partners may be aware of the ring during coitus. Intravaginal estradiol tablet. Low doses of 17-estradiol can be administered in the vagina using a hydrophilic slowrelease tablet containing 25 g 17-estradiol Vagifem ; . Maintenance therapy involves the administration of 1 tablet into the upper vagina every 3 days using a preloaded single-use applicator. Upon contact with the vaginal mucosa, a gel layer forms, allowing for rapid diffusion of estradiol. Eriksen and Rasmussen reported significant benefit over placebo with the vaginal tablet administered twice weekly.35 After 12 weeks of treatment, 89% of women demonstrated reversal of atrophic changes in the vagina and reported relief from vaginal dryness. Similarly, a recent multicentre, open, randomized Canadian trial by Rioux et al. reported equal therapeutic efficacy with 17-estradiol tablets and CEE cream for the treatment of vaginal atrophy.24 The authors identified a lack of significant systemic hormone absorption or endometrial effect with the intravaginal estradiol tablet. Other studies have reported similar findings.36, 37 As with the estradiol ring, the major advantages of the estradiol tablet are its ease of use and high long-term patient compliance. Rioux et al. noted that a higher number of women in their study found the tablet to be more acceptable than the cream.24 At study completion, 90% of tablet users but only 68% of cream users continued with the treatment. Selective estrogen receptor modulators. Whereas tamoxifen causes an increase in the vaginal maturation index, 38 raloxifene does not modify the vaginal index of the vaginal epithelium, nor has it been associated with increased frequency or severity of vaginal complaints during clinical trials.39 Two studies examining the concomitant use of raloxifene with CEE vaginal cream or polycarbophil gel found no independent effect of raloxifene on the vaginal mucosa.12, 39.

The Eli Lilly Canada representative provided trial reports, trial information and data, including guidance as to which reports referred to which unique studies. The reference lists from textbooks, reviews and reports of relevant primary studies were examined in an effort to identify additional trial material. Information was sought from the Journal of Bone and Mineral Research for the American Society for Bone and Mineral Research conference proceedings 1995 to 2001 inclusive Osteoporosis International for material presented at the World Congress on Osteoporosis 1995 to 2001 Maturitas 1995 to 2001 ; for the European Congress on Menopause; and the proceedings of American Society of Clinical Oncology meetings 1995 to 2001 ; . Journals such as the Journal of Clinical Oncology were also searched manually for potentially relevant reports 1995 to March 2002 ; . 3.1.2 Eligibility criteria A trial was eligible for inclusion if it met each of the following criteria: an RCT involving the use of raloxifene of any dose compared to other drugs or placebo for postmenopausal women with low BMD i.e., a T-score of more than 2.5 SD below the average value for peak young adult bone mass ; or women with higher BMD levels above the 2.5 SD threshold ; the inclusion of at least one of the following outcomes: incident radiographically confirmed vertebral fractures primary outcome BMD secondary outcome ; , because of its key role in the clinical diagnosis of osteoporosis and despite its poor predictive value for future fractures; 24 all reported adverse events e.g., breast cancer, venous thromboembolic events, hot flashes ; . All definitions of "postmenopausal" were included, e.g., natural or surgical post-hysterectomy ; . We accepted trials that involved co-therapies such as calcium, vitamin D or exercise. We excluded studies whose focus was the impact of raloxifene on biochemical markers of bone turnover, bone remodelling kinetics or bone histomorphometry; quality of life; cardiovascular risk e.g., C-reactive protein, serum lipoprotein or plasma homocysteine levels cognitive function; and neuromuscular function e.g., balance or falls ; . 3.1.3 Selection process The selection process by which evidence was organized and evaluated for relevance involved many steps, 31 which are described in Appendix 2. 3.1.4 Data abstraction After a calibration exercise involving five studies, two independent reviewers HMS, TC ; abstracted the content of each included trial using a form that focused on the report language of publication, year of publication, published versus unpublished status and sources of funding trial design, number of centres population sample size, age, years post-menopause, country in which the study was conducted intervention characteristics intervention length; raloxifene 4 and etoposide. It has oestrogen-like effects on the bone and blocks the effects of oestrogen on the breast. Raloxigene has been shown to improve BMD in women from age 31-80 with osteoporosis and reduce radiographic vertebral fracture but not non-vertebral fractures13. The role of raloxifene is not yet clear but it is possible that it may be useful for post-menopausal women who cannot tolerate a bisphosphonate. Rapidly regress in the presence of physiologic levels of estradiol 17 ; . Phase II drug resistance is also observed in MCF-7 cells treated with raloxifene for more than 1 year in vitro, as described by Liu et al. 46 ; . Thus, phase II drug resistance is not limited to tamoxifen or to development of tamoxifen-stimulated MCF-7 tumors in vivo but might result from a long-term exposure of breast cancer cells to tamoxifen or raloxifene. Our data Fig. 1, B and C ; suggest that the clinical use of fulvestrant to treat ER-positive tumors might not be beneficial during phase II resistance because the growth of such tumors is stimulated by treatment with estradiol plus fulvestrant. Furthermore, the use of aromatase inhibitors to block estradiol synthesis might stabilize disease rather than cause regression. Before the use of tamoxifen 47 49 ; or first-generation aromatase inhibitors 50 ; , postmenopausal women with breast cancer were treated with high-dose estrogens, such as diethylstilbestrol or ethinyl estradiol 49, 51, 52 ; . Results from our study suggest that low levels of estradiol 83.8 pg mL in serum ; 32 ; are sufficient to induce apoptosis and the regression of tamoxifen-stimulated breast tumors. A study by Lonning et al. 53 ; showed that standard high-dose estrogen 5 mg of diethylstilbestrol, given three times per day ; has a substantial antitumor effect in postmenopausal breast cancer patients who have been exposed to multiple endocrine therapies. Four of the 32 patients in that study achieved complete remission, six had partial remission, five had objective responses to high-dose diethylstilbestrol, and three had stable disease lasting from 6 months to more than 1 year. Clearly, there could be a profound advantage for patients if an apoptotic regimen targeting ER-positive tumors could be integrated into the overall treatment plan, especially because a recent laboratory study 17 ; shows that tamoxifen is again effective after such estrogen therapy. Song et al. 19 ; suggested that overexpression of FasL is important for estradiol-induced apoptosis of Fas-expressing breast cancer cells after long-term estrogen deprivation in vitro. In contrast, we demonstrate in this article that FasL protein is expressed at essentially the same level in both tamoxifen-naive and tamoxifen-stimulated MCF-7 tumors Fig. 4, A ; , regardless of the treatment, and thus would not be a limiting factor. Moreover, we show that both Fas mRNA and protein are induced in regressing tumors in response to tamoxifen in parental MCF-7E2 or to estradiol in MCF-7TAMLT tumors Fig. 4, A ; and could regulate apoptosis. Thus, apoptosis--induced initially by tamoxifen and later by estradiol--appears to be mediated by a common pathway. In estradiol-treated MCF-7TAMLT tumors, fulvestrant treatment completely blocked estradiol-induced regression, enhanced tumor growth Fig. 1, B and C ; , and, most importantly, blocked the estradiol-induced expression of Fas Fig. 4, A ; . Thus, both apoptosis and Fas expression appear to be mediated by the estradiolER complex. The finding that the pure antiestrogen fulvestrant could switch an estradiol-induced apoptotic signal to an estradiolinduced growth signal is intriguing. Fulvestrant is a steroidal compound with a 7 -alkylamide hydrocarbon side chain that reduces the level of cellular ERs 54 ; by disrupting dimerization of the ER; the protein monomer subsequently is targeted for ubiquitin-mediated degradation by the proteosome 13 ; . We have observed a novel action of fulvestrant--that the combined treatment of fulvestrant with estradiol stimulates the growth of breast tumors exposed to tamoxifen treatment for 5 years Fig. 1, B and C ; . Unexpectedly, fulvestrant partially blocked the and vepesid.

Elevated Levels of high-sensitivity C-Reactive Protein hs-CRP ; . We recommend achieving a hs-CRP under 1.3. Our program for lowering hs-CRP is in chapter 12. Metabolic Syndrome Syndrome X ; and Type II Diabetes. Our recommendation: have your fasting glucose and insulin levels checked and follow the guidelines in chapter 8. Hypertension. Optimal blood pressure is under 120 over 80. If your blood pressure is over this level, we recommend starting with a nutritional and supplement program and using prescription drugs only if that fails. The first step is to adopt our nutritional recommendations and attain your optimal weight. Determine if you have metabolic syndrome or type II diabetes and follow our program in chapter 9. These steps, especially adopting a low-carbohydrate, verylow-glycemic-index diet, are often adequate by themselves to resolve hypertension. Supplements helpful in resolving hypertension include the following and femara and raloxifene, for example, breast prevention raloxifene.
Raloxifene priceFor women with high estradiol levels, the evidence suggested that treating patients with raloxifene for 4 years would have avoided 47% of breast cancer cases. Salvia officinalis sage ; extract had beneficial effects on mild to moderately severe Alzheimer's disease in a very small, double-blind, placebo-controlled study. These results must be considered preliminary and need to be verified by more extensive research. Please keep in mind that herbal labels often misrepresent the amount of herbal substance in the bottle. Ginseng, another herbal product, is an example of this problem. An authoritative study in the New England Journal of Medicine December 19, 2002 ; found three different products had 11.9%, 220.8% and 327.7% of the amount of ginseng that were indicated on their labels.
