Zolasta 4mg Injection

Zoledronic Acid injection is a bisphosphonate indicated for the treatment of: Hypercalcemia of malignancy. Patients with multiple myeloma and patients with documented bone metastases from solid tumors, in conjunction with standard antineoplastic therapy. Prostate cancer should have progressed after treatment with at least one hormonal therapy. Limitations of Use: The safety and efficacy of Zoledronic Acid injection has not been established for use in hyperparathyroidism or non-tumor-related hypercalcemia. Hypercalcemia of Malignancy Zoledronic Acid injection is indicated for the treatment of hypercalcemia of malignancy defined as an albumin-corrected calcium (cCa) of greater than or equal to 12 mg/dL [3.0 mmol/L] using the formula: cCa in mg/dL=Ca in mg/dL + 0.8 ( 4.0 g/dL - patient albumin [g/dL]). Multiple Myeloma and Bone Metastases of Solid Tumors Zoledronic Acid injection is indicated for the treatment of patients with multiple myeloma and patients with documented bone metastases from solid tumors, in conjunction with standard antineoplastic therapy. Limitations of Use The safety and efficacy of Zoledronic Acid injection in the treatment of hypercalcemia associated with hyperparathyroidism or with other non–tumor-related conditions have not been established.

Patients being treated with Zoledronic Acid injection should not be treated with Reclast ®. Adequately rehydrate patients with hypercalcemia of malignancy prior to administration of Zoledronic Acid injection and monitor electrolytes during treatment. Renal toxicity may be greater in patients with renal impairment. Do not use doses greater than 4 mg. Treatment in patients with severe renal impairment is not recommended. Monitor serum creatinine before each dose. Osteonecrosis of the jaw (ONJ) has been reported. Preventive dental exams should be performed before starting Zoledronic Acid injection. Avoid invasive dental procedures. Severe incapacitating bone, joint, and/or muscle pain may occur. Discontinue Zoledronic Acid injection if severe symptoms occur. Atypical subtrochanteric and diaphyseal femoral fractures have been reported in patients receiving bisphosphonate therapy. These fractures may occur after minimal or no trauma. Evaluate patients with thigh or groin pain to rule out a femoral fracture. Consider drug discontinuation in patients suspected to have an atypical femur fracture. Hypocalcemia: Correct before initiating Zoledronic Acid injection. Adequately supplement patients with calcium and vitamin D. Monitor serum calcium closely with concomitant administration of other drugs known to cause hypocalcemia to avoid severe or life-threatening hypocalcemia Zoledronic Acid injection can cause fetal harm. Advise females of reproductive potential of potential risk to a fetus and to use effective contraception. Drugs with Same Active Ingredient or in the Same Drug Class Zoledronic Acid injection contains the same active ingredient as found in Reclast ® (Zoledronic Acid). Patients being treated with Zoledronic Acid injection should not be treated with Reclast or other bisphosphonates. Hydration and Electrolyte Monitoring Patients with hypercalcemia of malignancy must be adequately rehydrated prior to administration of Zoledronic Acid injection. Loop diuretics should not be used until the patient is adequately rehydrated and should be used with caution in combination with Zoledronic Acid injection in order to avoid hypocalcemia. Zoledronic Acid injection should be used with caution with other nephrotoxic drugs. Standard hypercalcemia-related metabolic parameters, such as serum levels of calcium, phosphate, and magnesium, as well as serum creatinine, should be carefully monitored following initiation of therapy with Zoledronic Acid injection. If hypocalcemia, hypophosphatemia, or hypomagnesemia occur, short-term supplemental therapy may be necessary. Abridged from the full prescribing information.

The most common adverse events (greater than 25%) were nausea, fatigue, anemia, bone pain, constipation, fever, vomiting, and dyspnea Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Hypercalcemia of Malignancy The safety of Zoledronic Acid injection was studied in 185 patients with hypercalcemia of malignancy (HCM) who received either Zoledronic Acid injection 4 mg given as a 5-minute intravenous infusion (n=86) or pamidronate 90 mg given as a 2-hour intravenous infusion (n=103). The population was aged 33 to 84 years, 60% male and 81% Caucasian, with breast, lung, head and neck, and renal cancer as the most common forms of malignancy. NOTE: pamidronate 90 mg was given as a 2-hour intravenous infusion. The relative safety of pamidronate 90 mg given as a 2-hour intravenous infusion compared to the same dose given as a 24-hour intravenous infusion has not been adequately studied in controlled clinical trials. Renal Toxicity Administration of Zoledronic Acid injection 4 mg given as a 5-minute intravenous infusion has been shown to result in an increased risk of renal toxicity, as measured by increases in serum creatinine, which can progress to renal failure. The incidence of renal toxicity and renal failure has been shown to be reduced when Zoledronic Acid injection 4 mg is given as a 15-minute intravenous infusion. Zoledronic Acid injection should be administered by intravenous infusion over no less than 15 minutes. The most frequently observed adverse events were fever, nausea, constipation, anemia, and dyspnea (see Table 4). Table 4 provides adverse events that were reported by 10% or more of the 189 patients treated with Zoledronic Acid injection 4 mg or pamidronate 90 mg from the two HCM trials. Adverse events are listed regardless of presumed causality to study drug.
