Narrative Review
A Review of Drug-Induced Hyponatremia

https://doi.org/10.1053/j.ajkd.2008.03.004Get rights and content

Hyponatremia (defined as a serum sodium level < 134 mmol/L) is the most common electrolyte abnormality in hospitalized patients. Certain drugs (eg, diuretics, antidepressants, and antiepileptics) have been implicated as established causes of either asymptomatic or symptomatic hyponatremia. However, hyponatremia occasionally may develop in the course of treatment with drugs used in everyday clinical practice (eg, newer antihypertensive agents, antibiotics, and proton pump inhibitors). Physicians may not always give proper attention in time to undesirable drug-induced hyponatremia. Effective clinical management can be handled through awareness of the adverse effect of certain pharmaceutical compounds on serum sodium levels. Here, we review clinical information about the incidence of hyponatremia associated with specific drug treatment and discuss the underlying pathophysiologic mechanisms.

Pathogenetic Aspects of Hyponatremia

Hyponatremia is ascribed to either water retention or (less often) loss of effective solute (sodium plus potassium) in excess of water. Because the capacity for water excretion normally is so great, retention of water resulting in hyponatremia takes place only in the presence of conditions that impair renal excretion of water. An exception to this rule is primary polydipsia, in which the excessive water intake can overwhelm even normal excretory capacity. Given that suppression of arginine

Drug-Induced Hyponatremia

Hyponatremia related to drug treatment can be caused by dozens, perhaps hundreds, of medications. Because hyponatremia can have many other causes, the diagnosis of drug-induced hyponatremia can easily be overlooked.

As shown in evidence from small studies and case reports, drugs may cause hyponatremia by affecting sodium homeostasis and water homeostasis. Clinical information about the incidence and pathophysiological process of hyponatremia of the most commonly offending agents is presented

Concluding Remarks

Hyponatremia occasionally may develop in the course of treatment with drugs used in everyday clinical practice (eg, newer antihypertensive agents, antibiotics, and PPIs). It should be noted that patients may receive complex drug regimens (eg, patients with diabetes mellitus) containing several candidates as the cause of hyponatremia. Discontinuation of treatment with these agents and avoidance of readministration is fully warranted. It is recommended that patients with acute severely
