lüll Management of the adverse effects associated with intravenous bisphosphonates Tanvetyanon T; Stiff PJAnn Oncol 2006[Jun]; 17 (6): 897-907Intravenous bisphosphonates are widely used to treat hypercalcemia and to reduce skeletal-related morbidity among cancer patients. However, serious complications, generally occurring in less than 2% of patients participated in phase III clinical trials, including acute systemic inflammatory reaction, ocular inflammation, renal failure, nephrotic syndrome, electrolyte imbalance, and osteonecrosis of the maxilla and mandible have all been increasingly reported. Yet, strategies to deal with these complications are becoming clear. Acute systemic inflammatory reaction is often self-limited and becomes less intense during subsequent treatments. For patients who develop ocular symptoms, prompt ophthalmologic evaluation is crucial to determine the safety of a subsequent bisphosphonate therapy. Patients who receive long-term pamidronate should be evaluated at intervals for early sign of nephritic syndrome as timely cessation of the agent may result in a full recovery. To reduce the risk of severe electrolyte abnormalities, particularly hypocalcemia, correcting any pre-treatment electrolyte abnormality and supplementing vitamin D and calcium may be helpful. Finally, to reduce the risk of osteonecrosis of the maxilla and mandible, obtaining a full dental evaluation before treatment and avoidance of invasive dental procedures is suggested. The three commonly used intravenous bisphosphonates (pamidronate, zoledronic acid, and ibandronate), are generally safe; ibandronate has to date been the least reported to be associated with renal side effects. As clinical indications of intravenous bisphosphonates continue to expand, prescribing clinicians should be familiar with these possible adverse effects and discuss them with patients before commencing or continuing on therapy.|Antineoplastic Agents/*adverse effects/therapeutic use[MESH]|Bone Density Conservation Agents/adverse effects[MESH]|Diphosphonates/administration & dosage/*adverse effects[MESH]|Humans[MESH]|Imidazoles/adverse effects[MESH]|Inflammation[MESH]|Infusions, Intravenous/adverse effects[MESH]|Osteoclasts/cytology/drug effects/pathology/physiology[MESH]|Pamidronate[MESH]|Zoledronic Acid[MESH] |
