    We evaluated adherence with raloxifene therapy compared with daily bisphosphonate in Asian postmenopausal women at increased risk of osteoporotic fractures. In this 12-month observational study conducted in Asia (Hong Kong, Malaysia, Pakistan, Philippines, Singapore, Taiwan), 984 postmenopausal women (aged 55 years or older) were treated with raloxifene 60 mg/day (n = 707; 72%) or daily bisphosphonate (alendronate 10 mg/day; n = 206; 21%, or risedronate 5 mg/day; n = 71; 7%) during their normal course of care. Patients were assessed at baseline, 6, and 12 months. Baseline characteristics (including age, race, education, menopausal status, and baseline fractures) were comparable between the raloxifene and bisphosphonate groups. More women on raloxifene completed the study compared with those on bisphosphonate (50.2% versus 37.5%; P < 0.001). Patients also took raloxifene for a longer period than bisphosphonate (median, 356 versus 348 days; P = 0.011). Compared with those taking bisphosphonate, significantly fewer patients taking raloxifene discontinued the study because of stopping treatment (5.7% versus 10.1%, P = 0.017) or changing treatment (2.8% versus 9.7%, P < 0.001). Inconvenient dosing was reported as a primary reason for discontinuation due to stopping or changing treatment in 19 (6.9%) bisphosphonate patients compared with 0 raloxifene patients. The percentage of patients who had consumed 80% or more of their study medication was similar for raloxifene patients (48-56 weeks; 95.2%) and bisphosphonate patients (48-56 weeks; 93.3%). More raloxifene patients responded that they were satisfied with their medication than bisphosphonate patients at 48-56 weeks (P = 0.002). We concluded that Asian postmenopausal women at increased risk of osteoporotic fractures showed a greater propensity to remain on raloxifene compared with bisphosphonate. The women on raloxifene exhibited lower discontinuation rates and higher treatment satisfaction.

    Tocotrienol has been shown to prevent bone loss in animal models of postmenopausal osteoporosis, but the low oral bioavailability might limit its use. A self-emulsifying drug delivery system (SEDDS) could increase the bioavailability of tocotrienol. However, evidence of this system in improving the skeletal effects of tocotrienol is scanty. This study aims to evaluate the therapeutic efficacy of annatto tocotrienol with SEDDS in a rat model of postmenopausal bone loss. Ten-month-old female Sprague Dawley rats were randomized into six groups. The baseline group was euthanatized at the onset of the study. Four other groups underwent ovariectomy to induce estrogen deficiency. The sham underwent similar surgery procedure, but their ovaries were retained. Eight weeks after surgery, the ovariectomized rats received one of the four different regimens orally daily: (a) SEDDS, (b) annatto tocotrienol [60 mg/kg body weight (b.w.)] without SEDDS, (c) annatto-tocotrienol (60 mg/kg b.w.) with SEDDS, (d) raloxifene (1 mg/kg b.w.). After eight weeks of treatment, blood was collected for the measurement of delta-tocotrienol level and oxidative stress markers. The rats were euthanized and their bones were harvested for the evaluation of the bone microstructure, calcium content and strength. Circulating delta-tocotrienol level was significantly higher in rats receiving annatto tocotrienol with SEDDS compared to the group receiving unformulated annatto-tocotrienol (p
