Toxikologische Informationen

Interactions · 5 Einträge

Potassium supplements should not be administered to patients receiving potassium-sparing drugs such as amiloride, spironolactone, and triamterene. /Potassium Supplements/

Concurrent use with potassium and sodium phosphates combination or monobasic potassium phosphate may increase plasma concentrations of salicylates since salicylate excretion is decreased in acidified urine; addition of these phosphates to patients stabilized on a salicylate may lead to toxic salicylate concentrations.

Concurrent use with foods or medicines containing phosphates will decrease iron absorption because of the formation of less soluble or insoluble complexes; iron supplements should not be taken within 1 hour before or 2 hours after ingestion of phosphates. /Phosphates/

Use of potassium phosphates injection in digitalized patients with severe or complete heart block is not recommended because of possible hyperkalemia. /Phosphates/

Although full-term infants suffering intrauterine growth restriction (IUGR) are routinely fed high-protein (HP) formulas to ensure catch-up growth, the effects of HP intake are poorly understood. An IUGR piglet model provides an opportunity to investigate these effects. Twelve IUGR piglets were artificially fed HP formulas (50% more protein in comparison to sow milk) from the 2nd day of life (d2) until d28. Unexpectedly, all HP piglets developed poor growth, severe hypotonia and polypnea between d10 and d16. One third died spontaneously. This syndrome was investigated to understand its pathophysiology and to adopt a strategy to restore health. Blood and urine biochemistry and amino acid concentrations were investigated in 10 HP piglets and 8 piglets that were fed a normal-protein (NP) formula. In comparison to NP piglets, HP piglets showed significant hypokalemia (2.7 +/- 0.6 vs. 3.6 +/- 0.6 mmol/L; p < 0.01), hypophosphatemia (1.5 +/- 0.2 vs. 3.0 +/- 0.3 mmol/L; p > 0.01), hypercalcemia (3.0 +/- 0.3 vs. 2.5 +/- 0.2 mmol/L; p < 0.01), hyperammonemia (365 +/- 4 vs. 242 +/- 15 umol/L; p < 0.05), elevated blood urea (6.5 +/- 0.4 vs. 1.3 +/- 0.4 mmol/L; p < 0.01) and elevated taurine concentrations (50.2 +/- 8.5 vs. 17.7 +/- 2.7 umol/L; p < 0.01). These altered parameters indicated inadequate potassium and phosphorus dietary supplies in HP piglets. When the HP formula was supplemented with monocalcium phosphate and monopotassium phosphate (HP-sup), serum biochemistry was normalized in piglets fed this formula (n = 8). This experimental strategy restored growth in IUGR piglets fed HP-sup, without a toxic effect. The current findings suggest that use of an HP formula without a proportional increase in its phosphorus and potassium content induces pathology similar to the refeeding syndrome in IUGR piglets.

Potassium is the principal intracellular cation. It helps transport dextrose across the cell membrane and contributes to normal renal function.

Potassium is the major cation of intracellular fluid and is essential for maintenance of acid-base balance, isotonicity, and electrodynamic characteristics of the cell. Potassium is an important activator in many enzymatic reactions and is essential to a number of physiologic processes including transmission of nerve impulses; contraction of cardiac, smooth, and skeletal muscles; gastric secretion; renal function; tissue synthesis; and carbohydrate metabolism. /Potassium Supplements/

Protein BindingIn healthy adults, plasma potassium concentrations generally range from 3.5-5 mEq/L. Plasma concentrations up to 7.7 mEq/L may be normal in neonates.

Potassium is the major cation of intracellular fluid and is essential for maintenance of acid-base balance, isotonicity, and electrodynamic characteristics of the cell. Potassium is an important activator in many enzymatic reactions and is essential to a number of physiologic processes including transmission of nerve impulses; contraction of cardiac, smooth, and skeletal muscles; gastric secretion; renal function; tissue synthesis; and carbohydrate metabolism. Phosphate is a major intracellular anion that participates in providing energy for metabolism of substrates and contributes to important metabolic and enzymatic reactions in almost all organs and tissues. Phosphate exerts a modifying influence on calcium concentrations, a buffering effect on acid-base equilibrium, and has a major role in the renal excretion of hydrogen ions.

Mechanism of Action · 1 Eintrag

hosphorus has a number of important functions in the biochemistry of the body. The bulk of the body's phosphorus is located in the bones, where it plays a key role in osteoblastic and osteoclastic activities. Enzymatically catalyzed phosphate-transfer reactions are numerous and vital in the metabolism of carbohydrate, lipid and protein, and a proper concentration of the anion is of primary importance in assuring an orderly biochemical sequence. ln addition, phosphorus plays an important role in modifying steady-state tissue concentrations of calcium. Phosphate ions are important buffers of the intracellular fluid, and also play a primary role in the renal excretion of the hydrogen ion. Oral administration of inorganic phosphates increases serum phosphate levels. Phosphates lower urinary calcium levels in idiopathic hypercalciuria.

Biological Half-LifeIn healthy children with phosphate overdose, half-life was 4.8 to 10.6 hours, and was prolonged to 17 hours in a child with renal insufficiency.

Potassium monophosphates are usually produced by the same process as the corresponding sodium salts, i.e., from phosphoric acid and potassium hydroxide. For KH2PO4, the cheaper potassium chloride is also used instead of KOH. Various methods have been suggested for quantitative removal of the hydrogen chloride formed: use of ion exchangers, long-chain tertiary amines, or distillation with octane.
