Off Label Uses
Bone loss associated with androgen deprivation treatment in prostate cancer (prevention)
Data from an open-label, randomized study supports the use of pamidronate in the prevention of bone loss associated with androgen deprivation treatment in prostate cancer. Pamidronate was found to prevent hip and lumbar spine bone loss [Smith 2001]. Additional trials may be necessary to further define the role of pamidronate in the treatment of this condition.
The definitive treatment for primary hyperparathyroidism is parathyroidectomy; however, pamidronate may be useful in patients who are not candidates for surgery, who refuse surgery, or who would benefit from a delay in surgery. Pamidronate is not curative, and doses must be repeated to control hypercalcemia. In patients with secondary hyperparathyroidism, pamidronate may help control hypercalcemia and allow for more aggressive use of calcitriol.
Data from an uncontrolled observational study supports the use of pamidronate in the treatment of osteogenesis imperfecta. Pamidronate improved clinical outcomes, reduced bone resorption and increased bone density [Glorieux 1998]. Additional trials may be necessary to further define the role of pamidronate in the treatment of this condition.
Symptomatic bone metastases of thyroid cancer
Data from a limited number of patients studied suggest that pamidronate may be beneficial for the treatment of symptomatic bone metastases of thyroid cancer [Vitale 2001]. Additional data may be necessary to further define the role of pamidronate in this condition.
Hypersensitivity to pamidronate, other bisphosphonates, or any component of the formulation
Note: Single doses should not exceed 90 mg.
Hypercalcemia of malignancy: IV:
Moderate cancer-related hypercalcemia (corrected serum calcium: 12 to 13.5 mg/dL): 60 to 90 mg, as a single dose over 2 to 24 hours
Severe cancer-related hypercalcemia (corrected serum calcium: >13.5 mg/dL): 90 mg, as a single dose over 2 to 24 hours
Re-treatment in patients who show an initial complete or partial response (allow at least 7 days to elapse prior to re-treatment): May re-treat at the same dose if serum calcium does not return to normal or does not remain normal after initial treatment.
Multiple myeloma, osteolytic bone lesions: IV: 90 mg over 4 hours once monthly:
Lytic bone disease: American Society of Clinical Oncology (ASCO) guidelines: 90 mg over at least 2 hours once every 3 to 4 weeks for up to 2 years; less frequent dosing (eg, once every 3 months) may be considered in patients with stable/responsive disease; discontinue after 2 years in patients with responsive and/or stable disease; resume therapy upon relapse with new-onset skeletal-related events (ASCO [Anderson 2018])
Newly diagnosed, symptomatic (off-label dose): 30 mg over 2.5 hours once monthly for at least 3 years (Gimsing 2010)
Breast cancer, osteolytic bone metastases: IV: 90 mg over 2 hours once every 3 to 4 weeks
Paget disease (moderate-to-severe): IV: 30 mg over 4 hours once daily for 3 consecutive days (total dose = 90 mg); may re-treat at initial dose if clinically indicated
Hyperparathyroidism (off-label use): IV: 15 to 90 mg as a single dose (Ammann 2003; Jansson 2004; Lu 2003); may be repeated every 1 to 2 months or when hypercalcemia recurs (Jansson 1991; Torregrosa 2003). The treatment period in clinical trials was up to 1 year (Torregrosa 2003).
Prevention of androgen deprivation-induced osteoporosis (off-label use): Males: IV: 60 mg over 2 hours once every 3 months (Smith 2001)
Refer to adult dosing. Begin at lower end of adult dosing range.
Dosing: Renal Impairment
Patients with serum creatinine >3 mg/dL were excluded from clinical trials; there are only limited pharmacokinetic data in patients with CrCl <30 mL/minute.
Manufacturer recommends the following guidelines:
Treatment of bone metastases: Use is not recommended in patients with severe renal impairment.
Renal impairment in indications other than bone metastases: Use clinical judgment to determine if benefits outweigh potential risks.
Multiple myeloma: American Society of Clinical Oncology (ASCO) guidelines (Kyle 2007):
Severe renal impairment (serum creatinine >3 mg/dL or CrCl <30 mL/minute) and extensive bone disease: 90 mg over 4 to 6 hours. However, a reduced initial dose should be considered if renal impairment was pre-existing.
Albuminuria >500 mg/24 hours (unexplained): Withhold dose until returns to baseline, then recheck every 3 to 4 weeks; consider reinitiating at a dose not to exceed 90 mg every 4 weeks and with a longer infusion time of at least 4 hours
Dosing adjustment in renal toxicity: In patients with bone metastases, treatment should be withheld for deterioration in renal function (increase of serum creatinine ≥0.5 mg/dL in patients with normal baseline [serum creatinine <1.4 mg/dL] or ≥1 mg/dL in patients with abnormal baseline [serum creatinine ≥1.4 mg/dL]). Resumption of therapy may be considered when serum creatinine returns to within 10% of baseline.
Dosing: Hepatic Impairment
Mild to moderate impairment: No dosage adjustment necessary.
Severe impairment: There are no dosage adjustments provided in the manufacturer’s labeling (has not been studied).
Powder for injection: Reconstitute by adding 10 mL of SWFI to each vial of lyophilized powder, the resulting solution will be 30 mg/10 mL or 90 mg/10 mL.
Pamidronate may be further diluted in 250 to 1000 mL of 1/2NS or NS or D5W. (The manufacturers recommend dilution in 1000 mL for hypercalcemia of malignancy, 500 mL for Paget disease and bone metastases of myeloma, and 250 mL for bone metastases of breast cancer.)
IV: Infusion rate varies by indication. Longer infusion times (>2 hours) may reduce the risk for renal toxicity, especially in patients with preexisting renal insufficiency. The manufacturer recommends infusing over 2 to 24 hours for hypercalcemia of malignancy; over 2 hours for osteolytic bone lesions with metastatic breast cancer; and over 4 hours for Paget disease and for osteolytic bone lesions with multiple myeloma. ASCO guidelines for bisphosphonate use in multiple myeloma recommend infusing pamidronate over at least 2 hours; if therapy is withheld due to renal toxicity, infuse over at least 4 hours upon reintroduction of treatment after renal recovery; infuse over 4 to 6 hours in patients with preexisting severe renal impairment and extensive bone disease (ASCO [Anderson 2018]).
Multiple myeloma or metastatic bone lesions from solid tumors or Paget disease: Take adequate daily calcium and vitamin D supplement (if patient is not hypercalcemic).
Powder for reconstitution: Store at 20°C to 25°C (68°F to 77°F). The reconstituted solution is stable for 24 hours stored under refrigeration at 2°C to 8°C (36°F to 46°F). The diluted solution for infusion is stable in D5W or NS at room temperature for up to 24 hours.
Solution for injection: Store at 20°C to 25°C (68°F to 77°F). The diluted solution for infusion is stable in D5W or NS at room temperature for up to 24 hours.
Aminoglycosides: May enhance the hypocalcemic effect of Bisphosphonate Derivatives. Monitor therapy
Angiogenesis Inhibitors (Systemic): May enhance the adverse/toxic effect of Bisphosphonate Derivatives. Specifically, the risk for osteonecrosis of the jaw may be increased. Monitor therapy
Deferasirox: Bisphosphonate Derivatives may enhance the adverse/toxic effect of Deferasirox. Specifically, the risk for GI ulceration/irritation or GI bleeding may be increased. Monitor therapy
Nonsteroidal Anti-Inflammatory Agents: May enhance the adverse/toxic effect of Bisphosphonate Derivatives. Both an increased risk of gastrointestinal ulceration and an increased risk of nephrotoxicity are of concern. Monitor therapy
Proton Pump Inhibitors: May diminish the therapeutic effect of Bisphosphonate Derivatives. Monitor therapy
Thalidomide: May enhance the nephrotoxic effect of Pamidronate. Monitor therapy

Concerns related to adverse effects:
• Bone fractures: Atypical femur fractures (AFF) have been reported in patients receiving bisphosphonates. The fractures include subtrochanteric femur (bone just below the hip joint) and diaphyseal femur (long segment of the thigh bone). Some patients experience prodromal pain weeks or months before the fracture occurs. It is unclear if bisphosphonate therapy is the cause for these fractures; atypical femur fractures have also been reported in patients not taking bisphosphonates, and in patients receiving glucocorticoids. Patients receiving long-term (>3 to 5 years) bisphosphonate therapy may be at an increased risk (Adler 2016; NOF [Cosman 2014]). Patients presenting with thigh or groin pain with a history of receiving bisphosphonates should be evaluated for femur fracture. Consider interrupting bisphosphonate therapy in patients who develop a femoral shaft fracture; assess for fracture in the contralateral limb.
• Musculoskeletal pain: Infrequently, severe (and occasionally debilitating) bone, joint, and/or muscle pain have been reported during bisphosphonate treatment. The onset of pain ranged from a single day to several months. Consider discontinuing therapy in patients who experience severe symptoms; symptoms usually resolve upon discontinuation. Some patients experienced recurrence when rechallenged with same drug or another bisphosphonate; avoid use in patients with a history of these symptoms in association with bisphosphonate therapy.
• Electrolyte abnormalities: Use has been associated with asymptomatic electrolyte abnormalities (including hypophosphatemia, hypokalemia, hypomagnesemia, and hypocalcemia). Rare cases of symptomatic hypocalcemia, including tetany, have been reported.
• Myelosuppression: Patients with preexisting anemia, leukopenia, or thrombocytopenia should be closely monitored during the first 2 weeks of treatment.
• Osteonecrosis of the jaw: Osteonecrosis of the jaw (ONJ), also referred to as medication-related osteonecrosis of the jaw (MRONJ), has been reported in patients receiving bisphosphonates. Known risk factors for MRONJ include invasive dental procedures (eg, tooth extraction, dental implants, boney surgery), cancer diagnosis, concomitant therapy (eg, chemotherapy, corticosteroids, angiogenesis inhibitors), poor oral hygiene, ill-fitting dentures, and comorbid disorders (anemia, coagulopathy, infection, preexisting dental or periodontal disease). Risk may increase with increased duration of bisphosphonate use and/or may be reported at a greater frequency based on tumor type (eg, advanced breast cancer, multiple myeloma). According to a position paper by the American Association of Maxillofacial Surgeons (AAOMS), MRONJ has been associated with bisphosphonates and other antiresorptive agents (denosumab), and antiangiogenic agents (eg, bevacizumab, sunitinib) used for the treatment of osteoporosis or malignancy; risk is significantly higher in cancer patients receiving antiresorptive therapy compared to patients receiving osteoporosis treatment (regardless of medication used or dosing schedule). MRONJ risk is also increased with monthly IV antiresorptive therapy compared to the minimal risk associated with oral bisphosphonate use, although risk appears to increase with oral bisphosphonates when duration of therapy exceeds 4 years. The AAOMS suggests that if medically permissible, initiation of IV bisphosphonates for cancer therapy should be delayed until optimal dental health is attained (if extractions are required, antiresorptive therapy should delayed until the extraction site has mucosalized or until after adequate osseous healing). Once IV bisphosphonate therapy is initiated for oncologic disease, procedures that involve direct osseous injury and placement of dental implants should be avoided. Patients developing ONJ during therapy should receive care by an oral surgeon (AAOMS [Ruggiero 2014]).
• Renal deterioration: Single pamidronate doses should not exceed 90 mg. Initial or single doses have been associated with renal deterioration, progressing to renal failure and dialysis. Glomerulosclerosis (focal segmental) with or without nephrotic syndrome has also been reported. Longer infusion times (>2 hours) may reduce the risk for renal toxicity, especially in patients with pre-existing renal insufficiency. Withhold pamidronate treatment (until renal function returns to baseline) in patients with evidence of renal deterioration.
• Breast cancer (metastatic): The American Society of Clinical Oncology (ASCO)/Cancer Care Ontario (CCO) updated guidelines on the role of bone-modifying agents (BMAs) in metastatic breast cancer patients (ASCO/CCO [Van Poznak 2017]). The guidelines recommend initiating a BMA (denosumab, pamidronate, zoledronic acid) in patients with metastatic breast cancer to the bone. One BMA is not recommended over another (evidence supporting one BMA over another is insufficient). The optimal duration of BMA therapy is not defined; however, the guidelines recommend continuing BMA therapy indefinitely. The analgesic effect of BMAs is modest and BMAs should not be used alone for pain management; supportive care, analgesics, adjunctive therapies, radiation therapy, surgery, and/or systemic anticancer therapy should be utilized. The ASCO/CCO guidelines are in alignment with prescribing information for dosing, renal dose adjustments, infusion times, prevention and management of osteonecrosis of the jaw, and monitoring of laboratory parameter recommendations.
• Hypercalcemia of malignancy (HCM): Adequate hydration is required during treatment (urine output ~2 L/day); avoid overhydration, especially in patients with heart failure.
• Hypoparathyroidism: Use caution with a history of thyroid surgery; patients may have relative hypoparathyroidism, predisposing them to pamidronate-related hypocalcemia.
• Multiple myeloma: Patients with Bence-Jones proteinuria and dehydration should be adequately hydrated prior to therapy. The American Society of Clinical Oncology (ASCO) has updated guidelines on bone-modifying agents (BMAs) in multiple myeloma (ASCO [Anderson 2018]). Bisphosphonate (pamidronate or zoledronic acid) therapy should be initiated in patients with radiographic or imaging evidence of lytic bone disease. Bisphosphonates may also be considered in patients with pain secondary to osteolytic disease and as adjunct therapy in patients receiving other interventions for fractures or impending fractures. The guidelines support utilizing IV bisphosphonates in patients with multiple myeloma and osteopenia (osteoporosis) but no radiographic evidence of lytic bone disease. Bisphosphonates are not recommended in patients with solitary plasmacytoma, smoldering (asymptomatic) or indolent myeloma with osteopenia in the absence of lytic bone disease. Bisphosphonates are also not recommended in monoclonal gammopathy of undetermined significance, unless osteopenia (osteoporosis) also is present. The guidelines recommend monthly treatment for a period of up to 2 years (less frequent dosing may be considered in patients with stable/responsive disease). After 2 years, consider discontinuing in responsive and stable patients, and reinitiate upon relapse if a new-onset skeletal-related event occurs. The ASCO guidelines are in alignment with the prescribing information for dosing, renal dose adjustments, infusion times, prevention and management of osteonecrosis of the jaw, and monitoring of laboratory parameter recommendations. According to the guidelines, in patients with extensive bone disease with existing severe renal disease (a serum creatinine >3 mg/dL or CrCl <30 mL/minute) pamidronate at a dose of 90 mg over 4 to 6 hours should be used (unless preexisting renal disease in which case a reduced initial dose should be considered). Monitor for albuminuria every 3 to 6 months; in patients with unexplained albuminuria >500 mg/24 hours, withhold the dose until level returns to baseline, then recheck every 3 to 4 weeks. Pamidronate may be reinitiated at a dose not to exceed 90 mg every 4 weeks with a longer infusion time of at least 4 hours.
• Renal impairment: Patients with serum creatinine >3 mg/dL were not studied in clinical trials; limited data are available in patients with CrCl <30 mL/minute. Evaluate serum creatinine prior to each treatment. For the treatment of bone metastases, use is not recommended in patients with severe renal impairment. With indications other than bone metastases, use clinical judgment to determine if benefits outweigh potential risks in patients with renal impairment.
Serum creatinine (prior to each treatment); serum electrolytes, including calcium, phosphate, magnesium, and potassium; CBC with differential; monitor for hypocalcemia for at least 2 weeks after therapy; dental exam and preventive dentistry prior to therapy for patients at risk of osteonecrosis, including all cancer patients; patients with pre-existing anemia, leukopenia, or thrombocytopenia should be closely monitored during the first 2 weeks of treatment; in addition, monitor urine albumin every 3 to 6 months in multiple myeloma patients
Multiple myeloma: Monitor serum creatinine (prior to each dose), serum calcium (regularly); vitamin D levels (intermittently), spot urine sample for albuminuria (every 3 to 6 months; for unexplained albuminuria, obtain 24 urine collection for total protein and urine protein electrophoresis; re-assess every 3 to 4 weeks) (ASCO [Anderson 2018]).
Prostate cancer: Androgen deprivation therapy (ADT)-associated osteoporosis: Monitor BMD every 18 to 24 months (IOF [Cianferotti 2017]).
Pregnancy Risk Factor
Adverse events were observed in animal reproduction studies. It is not known if bisphosphonates cross the placenta, but fetal exposure is expected (Djokanovic 2008; Stathopoulos 2011). Bisphosphonates are incorporated into the bone matrix and gradually released over time. The amount available in the systemic circulation varies by dose and duration of therapy. Theoretically, there may be a risk of fetal harm when pregnancy follows the completion of therapy; however, available data have not shown that exposure to bisphosphonates during pregnancy significantly increases the risk of adverse fetal events (Djokanovic 2008; Levy 2009; Stathopoulos 2011). Until additional data is available, most sources recommend discontinuing bisphosphonate therapy in women of reproductive potential as early as possible prior to a planned pregnancy; use in premenopausal women should be reserved for special circumstances when rapid bone loss is occurring (Bhalla 2010; Pereira 2012; Stathopoulos 2011). Because hypocalcemia has been described following in utero bisphosphonate exposure, exposed infants should be monitored for hypocalcemia after birth (Djokanovic 2008; Stathopoulos 2011).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience nausea, vomiting, lack of appetite, constipation, back pain, fatigue, sweating a lot, insomnia, cough, rhinorrhea, rhinitis, or injection site irritation. Have patient report immediately to prescriber signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain); signs of electrolyte problems (mood changes, confusion, muscle pain or weakness, abnormal heartbeat, seizures, lack of appetite, or severe nausea or vomiting); signs of a urinary tract infection (hematuria, burning or painful urination, polyuria, fever, lower abdominal pain, or pelvic pain); severe abdominal pain; tachycardia; abnormal heartbeat; signs of a low thyroid level (constipation; difficulty handling heat or cold; memory problems; mood changes; or burning, numbness, or tingling feeling); vomiting blood; black, red, or tarry stools; severe bone pain; severe joint pain; severe muscle pain; groin, hip, or thigh pain; severe dizziness; passing out; severe headache; severe loss of strength and energy; shortness of breath; edema; vision changes; or jaw pain or edema (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
