      Drug Name Polymyxin B Etidronic acid
      Mechanism Nephrotoxicity Nephrotoxicity
      Key Mechanism Factor 1
Factor Name Nephrotoxicity
Factor Description The combination of drugs that can induce nephrotoxicity may increase the risk of kidney injury. When kidney injury occurs, the inability to remove excess urine and waste from the body can lead to high levels of urea nitrogen, creatinine, and electrolytes (such as potassium and magnesium) in the blood.
      Mechanism Description
  • Increased risk of nephrotoxicity by the combination of Polymyxin B and Etidronic acid 

Recommended Action
      Management Caution is advised if pamidronate, zoledronic acid, or other intravenous formulations of bisphosphonates must be used in patients who have recently received or are receiving treatment with other potentially nephrotoxic agents (e.g., aminoglycosides, polypeptide and polymyxin antibiotics, vancomycin, amphotericin B, adefovir, cidofovir, tenofovir, foscarnet, cisplatin, gallium nitrate, lithium, mesalamine, certain immunosuppressants, intravenous pentamidine, high intravenous dosages of methotrexate, high dosages of nonsteroidal anti-inflammatory agents). Renal function and serum electrolytes should be monitored. Patients should have serum creatinine assessed prior to each treatment, and treatment should be withheld for renal deterioration.
