Lithium toxicity, also known as lithium overdose, is the condition of having too much lithium. Symptoms may include a tremor, increased reflexes, trouble walking, kidney problems, and an altered level of consciousness .
Nephrotoxicity is toxicity in the kidneys. It is a poisonous effect of some substances , both toxic chemicals and medications , on kidney function . [ 1 ] There are various forms, [ 2 ] and some drugs may affect kidney function in more than one way.
Lithium has been associated with several forms of kidney injury. [90] [91] It is estimated that impaired urinary concentrating ability is present in at least half of individuals on chronic lithium therapy, a condition called lithium-induced nephrogenic diabetes insipidus. [91]
Lithium-induced nephrogenic DI may be effectively managed with the administration of amiloride, a potassium-sparing diuretic often used in conjunction with thiazide or loop diuretics. Clinicians have been aware of lithium toxicity for many years, and traditionally have administered thiazide diuretics for lithium-induced polyuria and nephrogenic ...
Nephrogenic diabetes insipidus, recently renamed arginine vasopressin resistance (AVP-R) and previously known as renal diabetes insipidus, is a form of diabetes insipidus primarily due to pathology of the kidney.
“In some cases, it is hypothesized that rapid correction of hyperglycemia induced by these drugs, rather than a toxic effect of the drugs, could be associated with the ophthalmic complications ...
Kidney disease induced by iodinated contrast media (ICM) is called contrast induced nephropathy (CIN) or contrast-induced acute kidney injury (AKI). Currently, the underlying mechanisms are unclear. But there is a body of evidence that several factors including apoptosis-induction seem to play a role. [23]
As a result, kidney function and blood levels of lithium are monitored in patients being treated with lithium. [2] Therapeutic plasma levels of lithium range from 0.5 to 1.5 mEq/L, with levels of 0.8 or higher being desirable in acute mania. [14] Lithium levels should be above 0.6 mEq/L to reduce both manic and depressive episodes in patients. [15]
