Zoledronic acid was significantly more effective than placebo on most efficacy measures in patients with bone metastases secondary to other solid tumours (e.g. lung, prostate) and showed sustained efficacy for up to 15 months. Preliminary data indicate that its efficacy in these patients is sustained for up to 24 months. Estimates of the cost effectiveness of zoledronic acid in the treatment of prostate cancer were consistent with those of other bisphosphonates, and cost-effectiveness ratios were within limits considered acceptable economic value. Zoledronic acid was generally well tolerated, with a tolerability profile similar to that of pamidronic acid and placebo. As with other bisphosphonates, deterioration of renal function has occasionally been reported in patients receiving zoledronic acid and monitoring of serum creatinine is recommended during treatment. The efficacy of zoledronic acid is therefore well established in patients with hypercalcaemia of malignancy and, for up to 25 months, in the treatment of complications arising from metastatic bone disease in patients with multiple myeloma or solid tumours. The clinical profile of zoledronic acid compares favourably with that of pamidronic acid in patients with cancer and zoledronic acid has a more convenient administration schedule with the potential for better compliance. Thus, zoledronic acid is an effective bisphosphonate and is positioned to play an important role in the management of advanced cancer patients with bone metastases.
