Active Ingredient: Calcitonin
For the treatment of Paget’s disease, only in patients who do not respond to alternative treatments or for whom such treatments are not suitable, for example those with severe renal impairment.
For this indication, competent medicine agencies globally authorize below treatments:
For:
Regimen A: Intramuscular, 100 international units calcitonin, once daily.
Regimen B: Intramuscular, 50 international units calcitonin, 3 times weekly.
Regimen C: Subcutaneous, 100 international units calcitonin, once daily.
Regimen D: Subcutaneous, 50 international units calcitonin, 3 times weekly.
The recommended dosage is 100 IU per day, however, a minimum dosage regimen of 50 IU three times a week has achieved clinical and biochemical improvement. Dosage is to be adjusted to the individual patient’s needs.
Treatment should be discontinued once the patient has responded and symptoms have resolved. Duration of treatment should not normally exceed 3 months due to evidence of an increased risk of malignancies with long term calcitonin use. Under exceptional circumstances, e.g. in patients with impending pathologic fracture, treatment duration may be extended up to a recommended maximum of 6 months. Periodic re-treatment may be considered in these patients, and should take into account the potential benefits and evidence of an increased risk of malignancies and long term calcitonin use. The effect of calcitonin may be monitored by measurement of suitable markers of bone remodeling, such as serum alkaline phosphatase or urinary hydroxyproline or deoxypyridinoline. The dose may be reduced after the condition of the patient has improved.
For:
Nasal, between 100 international units calcitonin and 200 international units calcitonin, 2 times daily.
