Drug induced imbalance of sodium
Šteflová, Iveta ; Herink, Josef (advisor) ; Pourová, Jana (referee)
Iveta Šteflová Drug induced imbalance of sodium Diploma thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Pharmacy Department of Biological and Medical Science Supervisor: Doc.MUDr. Josef Herink, DrSc. Sodium (Na+ ) is the major extracellular cation. It plays an important role in maintaining membrane potential and depolarization that is the basic mechanism of transmission of the nerve impulse. It is involved in maintaining acid-base balance, osmotic pressure, water retention in the body. The largest part of the sodium is in the extracellular fluid where it is stored about 50 % of sodium. Plasma concentration of sodium is 140 ± 5 mmol/l. Drug-induced electrolyte disorders are increasingly reported and may be associated with considerable morbidity and mortality. The risk of drug-induced hyponatremia is generally higher than the risk of drug-induced hypernatremia. Hyponatremia is a common electrolyte disorder defined as a decrease plasma sodium concentration below 135 mmol/l. It is classified by the state of volume - hypovolemic, euvolemic and hypervolemic hyponatremia. It reflects the relative rate between sodium and water in the body. The most common cause is the syndrome of inappropriate secretion of antidiuretic hormone that induces euvolemic hyponatremia. Hypernatremia is...
