每年一次藥物治療可減少骨質疏松癥引發的骨折 【?2007-06-05 發布?】 美迪醫訊
最新報道一種每年只要進行一次的骨質疏松癥療法與現今月月或周周療法在預防骨折上能達到相同的效果。 加州大學的研究者發起了一項為期三年的國際性的研究,此研究涉及7,736名絕經后婦女。每年灌注這種藥物5mg后研究藥物的療效,觀察這種藥物是否能降低骨質疏松婦女椎骨和骨盆骨折的發生風險。 研究結果表明這種每年一次的療法能降低所有絕經期后患骨質疏松癥各種類型骨折的風險。包括降低70%發生脊椎骨折以及40%骨盆發生骨折的風險。這種效果維持了3年。觀察到這種療法心房顫動的可能性稍有增加。這項研究發表在新英格蘭醫學雜志2007年5月號。 “這是第一次,婦女可以選擇這種每年治療一次骨質疏松的療法而不是每周服藥丸。”第一作者,流行病和生物統計學專家Dennis Black博士介紹說。每周或每月進行治療很麻煩,于是這種一年一次的治療方法對絕經后婦女骨質疏松預防骨折來說是非常有價值的。 這種藥物將以Reclast為商品名由諾華公司(瑞士巴塞爾)生產。并正由美國食品和藥物管理局(FDA)審批。 來源:medinews.com Once-a-year Drug Reduces Osteoporosis Fractures A new study reported that a treatment for osteoporosis delivered once a year is as effective as current monthly or weekly osteoporosis regimens at reducing the incidence of bone fractures. Researchers at the University of California, San Francisco (UCSF; USA) conducted a three-year international study of 7,736 postmenopausal women with osteoporosis. The study evaluated the potential of using a once-yearly infusion of 5-mg of zoledronic acid to decrease the risk of vertebral and hip fractures in postmenopausal women with osteoporosis. Results of the study showed that treatment with zoledronic acid was very effective in reducing the incidence of all types of fractures in women with postmenopausal osteoporosis. This included a 70% reduction in the risk of spinal fractures and a 40% reduction in the risk of hip fractures. The effect was sustained over three years. The study did observe a small increase in the incidence of atrial fibrillation (AF) in patients who received zoledronic acid. The study was reported in the May 3, 2007, issue of the New England Journal of Medicine (NEJM). or the first time, women could have the option of being treated once a year for osteoporosis, instead of having to remember to take a weekly pill,?said lead author Dennis Black, Ph.D., a professor of epidemiology and biostatistics at the UCSF School of Medicine. 揂dherence to these weekly and monthly regimens is often a problem, so an annual treatment means patients are far more likely to actually receive valuable protection against potentially devastating fractures.? Zoledronic acid is an investigational drug in the bisphosphonate drug category that is being marketeded as Reclast by Novartis (Basel, Switzerland). It is the only once-yearly bisphosphonate treatment being studied for osteoporosis and is still in the approval process by the U.S. Food and Drug Administration (FDA). 《美迪醫訊》歡迎您參與新聞投稿,業務咨詢: 美迪醫療網業務咨詢
