As we age, our bones can start to become more fragile, and for many older adults, this can lead to osteoporosis. It is a condition where bones become so weak that they can fracture even from a simple fall or even a sneeze in severe cases. However, one of the best things about osteoporosis is that it is curable and various treatment options are available. In this article, we will be exploring different drug therapies which are used to treat osteoporosis. We will also discuss their mode of action, their benefits, and everything else you need to consider about them.

What Is Osteoporosis?
Osteoporosis is a condition that weakens bones by making them more porous ultimately making them more prone to fractures. It is more prevalent in elderly persons, especially in women who have gone through menopause. We begin to lose bone density when the rate of bone loss exceeds the rate of bone growth.
Treatment Options for Osteoporosis
Bisphosphonates
Bisphosphonates have been used for a long time and are the most commonly prescribed medications for osteoporosis. These include well-known drugs such as Alendronate and Zoledronic Acid.
How They Work: These drugs slow down the process of bone breakdown which in turn helps to maintain bone density.
Benefits: Bisphosphonates have been proven to reduce the risk of fractures, especially in the hip and spine which are the most common sites of fracture in elderly individuals.
Side Effects: Like any drug, bisphosphonates also have a few side effects. They can cause gastrointestinal issues like heartburn and in rare cases, jawbone problems. But for most people, the benefits outweigh the risks. These pills are taken weekly, monthly, or even yearly.
Denosumab
If bisphosphonates don’t work for you, or you can’t tolerate them, another option is Denosumab which is sold under the name Prolia.
How It Works: This drug is a bit different. It works by blocking a protein involved in bone breakdown which ultimately slows down bone loss and helps to build bone density.
Benefits: It’s great for people who are unable to take bisphosphonates or have underlying kidney issues. You only need to get an injection every six months, so it can be a convenient option for you.
Side Effects: Some people may experience skin rashes or infections and there’s also a small risk of unusual fractures or jaw problems.
SERMs (Selective Estrogen Receptor Modulators)
Raloxifene is a type of medication that mimics estrogen in some parts of the body like the bones but not others like the breast and uterus. It’s often recommended for postmenopausal women.
How It Works: It helps maintain bone density by mimicking the effects of estrogen on bones. After menopause, women naturally lose estrogen which can lead to post-menopausal symptoms and even osteoporosis as we have already explained.
Benefits: SERMs are especially good at reducing spine fractures. Along with that, these drugs are also helpful in lowering the risk of breast cancer.
Side Effects: It can increase the risk of blood clots and cause hot flashes, so it might not be for everyone.
Hormone Replacement Therapy (HRT)
For years, Hormone Replacement Therapy was a go-to treatment for osteoporosis, especially in women who also wanted relief from menopause symptoms. However, it has been largely replaced by other treatment methods.
How It Works: Estrogen helps slow bone loss, making it a natural option to prevent osteoporosis in postmenopausal women.
Benefits: It’s effective at preventing bone loss and may help with other menopause symptoms like hot flashes.
Risks: The big catch is that HRT comes with some significant risks, including an increased chance of heart disease, stroke, and breast cancer. Because of these risks, it’s not usually the first choice for treating osteoporosis anymore.
Parathyroid Hormone Analogues
If you’re dealing with severe osteoporosis or have already experienced fractures, medications like Teriparatide (Forteo) and Abaloparatide (Tymlos) might be your best option.
How They Work: Unlike other treatments that slow down or stop bone loss, these drugs actually stimulate the growth of new bone.
Benefits: These medications are usually reserved for people with severe osteoporosis and work well to reduce fractures.
Side Effects: They can cause dizziness, and leg cramps, and there have been some concerns about long-term use.
Calcium and Vitamin D
Even if you’re on medication for osteoporosis, you should get enough Calcium and Vitamin D. These nutrients help your bones stay strong and allow the medications to work efficiently.
How Much You Need: Most experts recommend that older adults aim for about 1,000-1,200 mg of calcium per day, and 600-800 IU of Vitamin D.
Risks: Too much calcium can lead to kidney stones, so it’s important to talk to your doctor so you can take the appropriate doses.
How Do You Choose the Right Treatment?
With so many options, how do you know which therapy is right for you? It depends on a variety of factors:
Your age and overall health: Some medications are better suited for people with certain health conditions.
Your fracture risk: If you’ve already had fractures, your doctor may recommend more aggressive treatment.
Bone density tests: Various medications have a threshold of bone density and cannot be used above a certain level. Doctors use DEXA scans to determine your bone density and prescribe the best option for you.
Personal preferences: Some treatments are as simple as a once-a-year infusion, while others require daily or weekly pills. You can always tell your doctor about your preferences.
What’s New in Osteoporosis Treatment?
The field of osteoporosis treatment is always evolving. The development of Romosozumab is one of the most exciting recent advances, but researchers are also looking into genetic therapies that may offer even more targeted and effective treatments in the future.

Conclusion
Osteoporosis doesn’t have to mean a life filled with fractures and reduced movement. As we have, mentioned above, various treatment options for osteoporosis not improve the prognosis of the disease but also improve the quality of life. The best method to make sure you’re headed in the correct direction for improved bone health is to work closely with your doctor to assess the benefits and drawbacks of each treatment choice.
