Prevention of contrast-induced nephropathy: a pharmacological overview

The use of contrast media in diagnostic procedures is a potential risk for the development of acute renal failure. To reduce the occurrence of contrast-induced nephropathy, assessment and subsequent minimization of risk factors is important. If risk factors are present, consider discontinuing concomitant nephrotoxic drugs, limiting exposure to contrast media or using an alternative imaging technique. Additionally, adequate intravenous hydration is universally recommended and should be employed in all patients.
