Nephrotoxicity (from Greek: nephros, "kidney") is a poisonous effect of some substances, both toxic chemicals and medication, on the kidneys. There are various forms of toxicity.^[1] Nephrotoxicity should not be confused with the fact that some medications have a predominantly renal excretion and need their dose adjusted for the decreased renal function (e.g., heparin).

Nephrotoxins are chemicals displaying nephrotoxicity.

The nephrotoxic effect of most drugs is more profound in patients already suffering from renal impairment. Some drugs may affect renal function in more than one way.

Types of toxicity

Cardiovascular

General: diuretics, β-blockers, vasodilator agents
Local: ACE inhibitors, ciclosporin,^[2] tacrolimus.^[2]

Direct tubular effect

Proximal convoluted tubule: Aminoglycoside antibiotics (e.g., gentamicin), amphotericin B, cisplatin, radiocontrast media, immunoglobulins, mannitol
Distal tubule: NSAIDs (e.g. aspirin, ibuprofen, diclofenac), ACE inhibitors, ciclosporin, lithium salts, cyclophosphamide, amphotericin B
Tubular obstruction: sulphonamides, methotrexate, aciclovir, diethylene glycol, triamterene.

Acute interstitial nephritis

β-lactam antibiotics, vancomycin, rifampicin, sulphonamides, ciprofloxacin, NSAIDs, ranitidine, cimetidine, furosemide, thiazides, phenytoin.

Chronic interstitial nephritis

Lithium (Li)
Ciclosporin^[3]

Acute glomerulonephritis

Drug-induced glomerular disease is not common but there are a few drugs that have been implicated. Glomerular lesions occur primarily through immune-mediated pathways rather than through direct drug toxicity.

Heroin and Pamidronate are known to cause focal segmental glomerulosclerosis
Gold salts therapy can cause membranous nephropathy^[3]
Penicillamine

Causes of diabetes insipidus

Lithium salts
Amphotericin B—reversible at low doses, irreversible at high doses
Fluoride
Demeclocycline
Foscarnet.

Other nephrotoxins

Heavy metals interfere with enzymes of energy metabolism.
Aristolochic acid, found in some plants and in some herbal supplements derived from those plants, has been shown to have nephrotoxic effects on humans.
Rhubarb contains some nephrotoxins which can cause inflammation of the kidneys in some people.

Surveillance

Nephrotoxicity is usually monitored through a simple blood test. A decreased creatinine clearance indicates poor renal function. Normal creatinine level is between 80 - 120 μmol/L. In interventional radiology, a patient's creatinine clearance levels are all checked prior to a procedure.

Serum creatinine is another measure of renal function, which may be more useful clinically when dealing with patients with early kidney disease.
