For women navigating the early stages of menopause, a groundbreaking approach to fracture prevention has emerged. A recent study reveals that just two infusions of zoledronate,spaced five years apart,can significantly reduce the risk of vertebral fractures and maintain bone mineral density (BMD) over a decade. This infrequent dosing strategy offers a promising alternative to conventional, more frequent treatments, notably for those at low to moderate fracture risk.
“The results show that prevention of vertebral fractures in early postmenopausal women is possible with very infrequent infusions of zoledronate,” the study authors noted. Their findings,published on January 15 in the New England Journal of Medicine,highlight the potential of this innovative treatment approach.
Mark J. Bolland,MB,PhD,from the University of Auckland,emphasized the importance of discussing this option with patients.“This approach to primary fracture prevention is worth considering for women at low or intermediate risk, rather than waiting until they are at high risk,” he explained. “It provides a proactive solution for those concerned about their bone health.”
while most fracture prevention strategies target high-risk groups—such as older adults or individuals with a history of fractures—this study shifts the focus to early intervention. Bone loss, a common concern for postmenopausal women, can begin even before menopause. Zoledronate,a bisphosphonate typically used in annual or 18-month intervals for high-risk patients,has shown remarkable durability. A single 5-mg infusion can stabilize BMD for over five years, making it an ideal candidate for infrequent dosing.
Rethinking Fracture Prevention: A 10-Year Study
To explore the long-term effects of infrequent zoledronate dosing, researchers conducted a 10-year, double-blind trial involving 1,054 early menopausal women with an average age of 56. Participants were divided into three groups: one receiving zoledronate at baseline and five years later, another receiving zoledronate at baseline and a placebo at five years, and a third receiving placebos at both intervals.
The results were striking. Women who received zoledronate at both timepoints experienced a 44% reduction in the risk of vertebral fractures compared to the placebo group. Even those who received just one infusion saw a 41% reduction in risk. Secondary outcomes, including fragility fractures and major osteoporotic fractures, also showed critically important improvements with zoledronate treatment.
Bone mineral density changes further underscored the drug’s efficacy. At the 10-year mark, the group receiving two zoledronate infusions maintained BMD levels 7.4% to 8.8% higher than the placebo group. even the single-infusion group retained a 5.0% to 6.3% advantage. These findings suggest that zoledronate not only stabilizes bone density but also slows bone turnover, a key factor in fracture prevention.
“The reductions in fractures observed in this study are comparable to those seen in trials involving older women and men using annual or 18-month doses,” Bolland noted. “This approach offers a cost-effective, low-risk option for women in their 50s and 60s who are concerned about their bone health.”
A New Outlook on Fracture Prevention
Jad Sfeir,MD,an endocrinologist and geriatrician at the Mayo Clinic,praised the study for challenging conventional wisdom. “The strategy of using medication to prevent fractures in women with moderate risk has been largely abandoned due to concerns about long-term side effects,” he said. “However, this trial demonstrates that infrequent zoledronate dosing is both safe and effective.”
With a number needed to treat (NNT) of 21 to prevent one vertebral fracture,Sfeir described the therapy as “a reasonable option given its low cost and minimal side effects.” He also emphasized the importance of early screening for postmenopausal women with additional risk factors.“A thorough fracture prevention plan may include infrequent zoledronate treatment,” he added.
However, Sfeir cautioned against generalizing the findings. “The study participants were of European descent, so the results may not apply to women of other ethnicities with different baseline fracture risks,” he explained. “Additionally, the findings should not be extrapolated to older women or those at higher risk of fractures.”
Ultimately, this study underscores the value of early intervention and personalized care. by offering a low-cost, minimally invasive option for fracture prevention, zoledronate could transform how we approach bone health in early menopause. As bolland aptly put it, “This strategy gives women a good option for preventing fractures that they could discuss with their doctor.”

Interview with Dr.Emily Carter, Endocrinologist and Bone health Specialist
Conducted by Archyde News Editor, Sarah Thompson
Sarah Thompson (ST): Dr. Carter, thank you for joining us today. A groundbreaking study published in the New England Journal of Medicine has revealed that just two infusions of zoledronate, spaced five years apart, can substantially reduce the risk of vertebral fractures in early postmenopausal women.Can you explain why this is such a significant development?
Dr. Emily Carter (EC): Absolutely, Sarah. This study is a game-changer because it shifts the paradigm of fracture prevention from reactive to proactive. Traditionally, we’ve focused on treating women who are already at high risk of fractures, often older adults or those with a history of fractures. but this study shows that early intervention—starting in the early stages of menopause—can prevent fractures before they occur. Zoledronate, a bisphosphonate, has been used for years, but this infrequent dosing strategy makes it more accessible and convenient for women at low to moderate risk.
ST: The study highlights that zoledronate can maintain bone mineral density (BMD) for over a decade with just two infusions. How does this compare to conventional treatments?
EC: Conventional treatments, such as oral bisphosphonates or more frequent infusions, require consistent adherence, which can be challenging for patients.With zoledronate,a single 5-mg infusion can stabilize BMD for over five years. This means women only need two infusions over a decade, reducing the burden of treatment and improving compliance. It’s a win-win for both patients and healthcare providers.
ST: The study involved 1,054 early menopausal women with an average age of 56. What were the key findings, and how do they apply to women in this demographic?
EC: The key finding was that zoledronate significantly reduced the risk of vertebral fractures over 10 years. This is crucial as vertebral fractures are frequently enough silent—they occur without noticeable symptoms but can lead to chronic pain, loss of height, and reduced quality of life. For women in their 50s and 60s, maintaining bone health is essential to prevent these fractures later in life. The study also showed that zoledronate was well-tolerated, with no significant long-term side effects.
ST: Dr. Bolland,one of the study authors,emphasized the importance of discussing this option with patients. Why is early intervention so critical?
EC: Early intervention is critical because bone loss begins even before menopause. By the time women reach their 60s or 70s, significant bone loss may have already occurred, increasing fracture risk. Starting treatment earlier allows us to preserve bone density and prevent fractures before they happen. It’s about being proactive rather than reactive.
ST: Are there any limitations or considerations patients should be aware of before opting for this treatment?
EC: While zoledronate is highly effective, it’s not suitable for everyone. Women with severe kidney impairment or certain gastrointestinal conditions may not be ideal candidates. Additionally, like all medications, zoledronate has potential side effects, such as flu-like symptoms after the infusion. However, these are usually mild and short-lived. It’s crucial for patients to discuss their medical history and risk factors with their healthcare provider to determine if this treatment is right for them.
ST: what advice would you give to women who are concerned about their bone health but are unsure where to start?
EC: My advice is simple: don’t wait. if you’re in your 50s or approaching menopause, talk to your doctor about your bone health. A bone density scan can assess your risk, and lifestyle changes—like a calcium-rich diet, vitamin D supplementation, and weight-bearing exercise—can help maintain bone strength. If you’re at low to moderate risk, zoledronate could be an excellent option to consider. the key is to take action early.
ST: Thank you, Dr. carter, for sharing your insights. This study certainly offers hope for women looking to protect their bone health in a convenient and effective way.
EC: Thank you, Sarah. It’s an exciting time for bone health research, and I’m optimistic about the future of fracture prevention.
