Medicines to Treat Paget's Disease


Paget's disease (also known as Paget's disease of bone or as deforming osteitis) is a metabolic pathology of the bone, in which there is an alteration in the bone remodeling processes. This alteration is characterized by an imbalance between the destruction and the deposition of new mineralized bone matrix, which is replaced by a weaker structure. This phenomenon consequently leads to deformation, fragility and bone fractures.
Paget's disease mainly affects elderly patients and can affect any bone in the body.


The triggering cause of Paget's disease has not yet been identified.
S "hypothesizes that some genetic alterations concerning certain types of genes are involved in the onset of the disease, which code for proteins involved in the activity of osteoclasts (responsible for the reabsorption of the bone matrix).
An "other rather accredited hypothesis is that according to which Paget's disease is caused by a" viral infection sustained by a slow-replicating virus. It is thought that this virus "settles" in the bone cells several years before the onset of the first symptoms and that it can then begin to attack the osteoclasts, thus starting an inflammatory process that will then lead to the development of the disease. The virus in question appears to be a paramyxovirus, but there is still no firm evidence to confirm this theory.


In many cases, Paget's disease is asymptomatic or presents with mild symptoms that can be confused with other bone diseases and therefore make it difficult to identify.
However, the most common symptom of Paget's disease is bone pain localized in the area affected by the disease. In addition to this, joint stiffness, numbness, tingling sensation, weakness, fractures, deformity and bone fragility may also occur.
If the bones affected by the disease are those of the skull, then headaches, tinnitus and hearing loss can also arise.
Furthermore, Paget's disease can cause cardiac, neurological, rheumatological and metabolic complications, giving rise to disorders such as - for example - heart failure, ventricular hypertrophy, hypercalcemia, kidney stones, paraesthesia, vertebral stenosis, asthenia, dizziness and primary hyperparathyroidism.

In the treatment of Paget's disease, early diagnosis is key. In fact, drug therapy is all the more effective the sooner it is administered. Especially when it is performed before the onset of any complications.
The first choice drugs used in the treatment of Paget's disease are bisphosphonates.
In patients who cannot tolerate the aforementioned bisphosphonate treatment, on the other hand, calcitonin-based therapy can be started, even if it is less effective.
Finally, for the control of bone pain caused by the disease, the doctor may decide to prescribe the use of non-steroidal anti-inflammatory drugs.
Finally, in extreme cases, the doctor may deem it necessary to resort to surgical treatment.

The following are the classes of drugs most used in the therapy against Paget's disease and some examples of pharmacological specialties; it is up to the doctor to choose the active ingredient and dosage most suitable for the patient, based on the severity of the disease, the state of health of the patient and his response to treatment.


As mentioned, bisphosphonates are the drugs of choice for the treatment of Paget's disease. In fact, they are able to reduce bone turnover, decrease pain and promote the healing of osteoclastic lesions, thus also promoting the restoration of normal bone matrix.
Among the various active ingredients that can be used, we remember:

  • Neridronic acid (Nerixia ®): Neridronic acid is available for parenteral administration. When used for the treatment of Paget's disease, the dose of drug usually used is 100 mg per day, to be administered via a slow intravenous infusion for two consecutive days. The overall drug dose can also be divided into smaller doses to be administered intramuscularly for up to eight consecutive days.
    This therapeutic cycle can possibly be repeated after an interval of at least six months.
  • Alendronic Acid (Alendros ®, Fosamax ®, Adronat ®, Dronal ®): Alendronic acid is available for oral administration. The dose of drug usually administered is 10 mg per day, or 70 mg once a week.
    The drug should be administered in the morning, at least thirty minutes before the intake of any food, drink or other drug.
  • Clodronic acid (Clasteon ®, Clody ®, Difosfonal ®): clodronic acid is available for both oral and parenteral administration (intramuscular and intravenous).

The amount of drug to be taken and the route of administration must be established by the physician for each patient.


Calcitonin is a hormone that is naturally produced by the thyroid and is involved in the regulation of calcium and bone metabolism.
Synthetic calcitonin (Calco ®, Calcitonin Sandoz ®, Biocalcin ®) can be used in those patients who cannot tolerate bisphosphonate-based treatment.However, it is less effective than the latter and its use is also associated with an increased risk of developing cancer.
Synthetic calcitonin is able to regulate calcium levels and reduce bone pain. Generally - when used for the treatment of Paget's disease - synthetic calcitonin is administered at a dose of 100 I.U. per day through an intramuscular or subcutaneous injection, for a period that can vary from 2-4 weeks up to a maximum of 3-6 months. The drug can be administered either in a single dose or in two divided doses.
In any case, the duration of treatment will have to be determined by the doctor on an individual basis.


Non-steroidal anti-inflammatory drugs can be used to control bone pain caused by Paget's disease. Among the most used active ingredients, we remember:

  • Ibuprofen (Brufen ®, Moment ®, Nurofen ®, Arfen ®, Actigrip fever and pain ®, Vicks fever and pain ®): when ibuprofen is administered orally, the dose used should not exceed 1,200-1,800 mg of drug per day The exact amount of active ingredient to be taken must be established by the doctor for each patient.
  • Naproxen (Momendol ®, Synflex ®, Xenar ®): if naproxen is administered orally, the usual daily dose is 500-1,000 mg of drug, to be taken in divided doses every 12 hours.
  • Acetylsalicylic Acid (Aspirin ®, Alkaeffer ®): Acetylsalicylic acid is available for oral and parenteral administration.

When administered orally, the dose of drug usually used in adults ranges from 325 mg to 1,000 mg, to be taken 2-3 times a day.
When administered intravenously or intramuscularly, however, the dose of drug used in adults is 500-1,000 mg, to be administered every 6, 8, or 12 hours.
However, the exact amount of drug to be taken and the route of administration must be determined by the doctor.


Paracetamol (Tachipirina ®, Efferalgan ®, Panadol ®) can also be used for the treatment of bone pain caused by Paget's disease, thanks to its analgesic properties. It is a drug available in different pharmaceutical formulations. When used orally, the doses of acetaminophen usually used are 500-1000 mg, to be taken as needed up to 3-4 times a day.
