Treatment of Osteoporosis in Postmenopausal Women: The recommended regimen is a 5 mg infusion once a year given intravenously over no less than 15 minutes.Prevention of Osteoporosis in Postmenopausal Women: The recommended regimen is a 5 mg infusion given once every 2 years intravenously over no less than 15 minutes.Osteoporosis in Men: The recommended regimen is a 5 mg infusion once a year given intravenously over no less than 15 minutes.Treatment and Prevention of Glucocorticoid-Induced Osteoporosis: The recommended regimen is a 5 mg infusion once a year given intravenously over no less than 15 minutes.Treatment of Paget’s Disease of Bone: The recommended dose is a 5 mg infusion. The infusion time must not be less than 15 minutes given over a constant infusion rate.Re-treatment of Paget’s Disease: Re-treatment with Zoledronic Acid may be considered in patients who have relapsed, based on increases in serum alkaline phosphatase, or in those patients who failed to achieve normalization of their serum alkaline phosphatase, or in those patients with symptoms, as dictated by medical practice.Calcium and Vitamin D Supplementation: Instruct patients being treated for Paget’s disease of bone on the importance of calcium and vitamin D supplementation in maintaining serum calcium levels, and on the symptoms of hypocalcemia. All patients should take 1500 mg elemental calcium daily in divided doses (750 mg two times a day, or 500 mg three times a day) and 800 international units vitamin D daily, particularly in the 2 weeks following Zoledronic Acid administration.Instruct patients being treated for osteoporosis to takesupplemental calcium and vitamin D if their dietary intake is inadequate. An average of at least 1200 mg calcium and 800-1000 international units vitamin D daily is recommended. Important Administration Instructions- Zoledronic Acid injection must be administered as an intravenous infusion over no less than 15 minutes Patients must be appropriately hydrated prior to administration of Zoledronic Acid Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit Intravenous infusion should be followed by a 10 mL normal saline flush of the intravenous line Administration of acetaminophen following Zoledronic Acid administration may reduce the incidence of acute-phase reaction symptoms. Method of Administration- The Zoledronic Acid infusion time must not be less than 15 minutes given over a constant infusion rate The intravenous infusion should be followed by a 10 mL normal saline flush of the intravenous line Zoledronic Acid solution for infusion must not be allowed to come in contact with any calcium or other divalent cation-containing solutions, and should be administered as a single intravenous solution through a separate vented infusion line If refrigerated, allow the refrigerated solution to reach room temperature before administration. After opening, the solution is stable for 24 hours at 2°C to 8°C

Side Effects

The most common adverse reactions (greater than 10%) were pyrexia, myalgia, headache, arthralgia, pain in extremity. Other important adverse reactions were flu-like illness, nausea, vomiting, diarrhea, and eye inflammation

Precaution

Hypocalcemia may worsen during treatment. Patients must be adequately supplemented with calcium and vitamin D. Renal Impairment: A single dose should not exceed 5 mg and the duration of infusion should be no less than 15 minutes. Renal toxicity may be greater in patients with underlying renal impairment or with other risk factors, including advanced age or dehydration. Monitor creatinine clearance before each dose. Osteonecrosis of the Jaw (ONJ) has been reported. All patients should have a routine oral exam by the prescriber prior to treatment. Atypical Femur Fractures have been reported. Patients with thigh or groin pain should be evaluated to rule out a femoral fracture. Severe Bone, Joint, and Muscle Pain may occur. Withhold future doses of Zoledronic Acid if severe symptoms occur.

Interaction

Aminoglycosides: May lower serum calcium for prolonged periods.Loop diuretics: May increase risk of hypocalcemia.Nephrotoxic drugs: Use with caution.Drugs primarily excreted by the kidney: Exposure may be increased with renal impairment. Monitor serum creatinine in patients at risk.

Pregnancy & Breastfeeding use

Zoledronic Acid can cause fetal harm. Women of childbearing potential should be advised. Zoledronic Acid should not be given to nursing women.

Contraindication

Hypocalcemia Patients with creatinine clearance less than 35 mL/min and in those with evidence of acute renal impairment Hypersensitivity to any component of Zoledronic Acid

Special Warning

Pediatric Use: Not indicated for use in pediatric patients.Geriatric Use: Special care to monitor renal function.Renal impairment: Zoledronic Acid is contraindicated in patients with creatinine clearance less than 35 mL/min and in those with evidence of acute renal impairment. Therefore, no dosage adjustment is required in patients with a creatinine clearance of greater than or equal to 35 mL/min.Hepatic impairment: Zoledronic Acid is not metabolized in the liver. No clinical data are available for use of Zoledronic Acid in patients with hepatic impairment.

Acute Overdose

Patients who have received doses higher than those recommended should be carefully monitored. Over dosage may cause clinically significant renal impairment, hypocalcemia, hypophosphatemia, and hypomagnesemia. Clinically relevant reductions in serum levels of calcium, phosphorus, and magnesium should be corrected by intravenous administration of calcium gluconate, potassium or sodium phosphate, and magnesium sulfate, respectively. Single doses of Zoledronic Acid should not exceed 5 mg and the duration of the intravenous infusion should be no less than 15 minutes.
