Osteoporosis: New Long-Acting Treatments and Their Benefits - Orthopedics

Share to:

Osteoporosis is diagnosed when a patient's bone mineral density (BMD) score is -2.5 or lower. A score of -3.1 indicates a more severe level of osteoporosis, which increases the risk of fractures and other complications. It is important to discuss treatment options and management strategies with your healthcare provider?


Excerpt from the internet: On July 23, 2007, Professor Tsai Ke-Sung, Vice President of National Taiwan University Hospital, published an article on the concept of targeted treatment for osteoporosis with long-acting bisphosphonate injections to address gastrointestinal discomfort from oral medications.
Preventing osteoporosis could become as convenient as preventing influenza! There has been a breakthrough in osteoporosis medications; in the future, a single injection every season could effectively preserve bone density and reduce the risk of fractures, potentially rewriting current treatment guidelines for osteoporosis.
The vast majority of osteoporosis patients are elderly, and the previous requirement to take daily medication was quite inconvenient for them, leading to missed doses or interactions that could affect efficacy.
Once patients are unable to adhere to their medication regimen, the effectiveness is significantly compromised, leaving them under the shadow of fractures.
In light of this, extending the duration of drug effects and reducing the frequency of dosing has been a goal for many multinational pharmaceutical companies in drug development.
Currently, many new medications for chronic diseases are actively moving towards the latest concept of "vaccination." Osteoporosis medications have now progressed to the stage of long-acting formulations, which can replace traditional daily dosing, making osteoporosis treatment as convenient as vaccination for infection prevention, thereby improving patient compliance and enhancing treatment success rates.
Long-acting bisphosphonate medications represent a new trend in treatment: fast, safe, and effective.
Currently, new osteoporosis medications are generally classified into four categories, with long-acting bisphosphonates being the most noteworthy and widely used.
These medications have evolved from daily dosing to weekly dosing, and now require only a quarterly injection, with future developments aiming for an annual injection.
In fact, similar to many targeted cancer therapies, the introduction of bisphosphonate injections embodies the concept of targeted treatment for osteoporosis, directly addressing the disease by supplementing what patients lack and minimizing unnecessary side effects.
The quarterly bisphosphonate injections currently available on the market are relatively affordable compared to other new medications, helping to alleviate the financial burden on patients, with costs around five to six thousand NTD per injection, averaging about two thousand NTD per month.
May I ask if Keelung Hospital offers such pharmaceutical treatments and services?

Hello: In response to your question, a T-score less than -2.5 indicates osteoporosis.
Currently, our hospital offers a once-weekly long-acting bisphosphonate medication, Fosamax.
However, the quarterly injectable medication mentioned by Professor Tsai has not yet been introduced at our hospital, but there is a high possibility it will be available in the future.
Please stay tuned! Wishing you all the best.

Osteoporosis is a significant health concern, particularly among the elderly population, as it increases the risk of fractures and other complications. Recent advancements in treatment options, particularly long-acting medications, have revolutionized the management of this condition. One of the most promising developments is the introduction of long-acting bisphosphonate injections, which can be administered quarterly, significantly improving patient compliance and treatment outcomes.

Traditionally, osteoporosis treatments required daily or weekly oral medications, which posed challenges for many patients. Forgetting to take medication or experiencing gastrointestinal side effects often led to suboptimal adherence, diminishing the effectiveness of the treatment. The new long-acting bisphosphonate injections address these issues by allowing patients to receive treatment just once every three months, or potentially even once a year in the future. This approach not only simplifies the treatment regimen but also enhances the likelihood of patients maintaining their therapy, thereby reducing the risk of fractures.

The mechanism of action for bisphosphonates involves inhibiting osteoclast activity, which are the cells responsible for bone resorption. By reducing bone turnover, these medications help to maintain or even increase bone density, which is crucial for preventing fractures. The long-acting formulations are particularly beneficial because they provide a sustained effect, ensuring that patients receive continuous protection against bone loss without the need for frequent dosing.

In addition to the convenience of less frequent dosing, these long-acting treatments are designed to minimize side effects. Traditional oral bisphosphonates can cause gastrointestinal issues, which may deter patients from continuing their medication. The injectable forms bypass the gastrointestinal tract, thereby reducing the likelihood of these adverse effects and making treatment more tolerable for patients.

Moreover, the cost of these long-acting bisphosphonate injections is relatively reasonable compared to other treatments available on the market. With prices around $200-300 per month, they offer a cost-effective solution for many patients, especially when considering the potential costs associated with treating fractures resulting from untreated osteoporosis.

It is essential for patients and healthcare providers to engage in thorough discussions regarding treatment options. Factors such as the patient's overall health, the severity of osteoporosis, and any existing comorbidities should be considered when selecting the most appropriate therapy. For instance, patients with a history of venous thromboembolism may need to avoid certain medications like Raloxifene, which carries a risk of increasing blood clot formation.

In conclusion, the emergence of long-acting bisphosphonate injections represents a significant advancement in the management of osteoporosis. By improving adherence, reducing side effects, and providing effective treatment, these medications can help patients maintain their bone health and reduce the risk of fractures. As healthcare providers continue to explore innovative treatment options, it is crucial for patients to stay informed and actively participate in their treatment decisions. If you are interested in these new treatment options, it is advisable to consult with your healthcare provider to determine the best course of action tailored to your specific needs.
