| potassium sparing diuretics | Diuretic agents that, unlike most diuretics, retain potassium; examples are triamterene and amiloride. Often used together with diuretics that promote the loss of both sodium and potassium. Used in hypertension and in congestive heart failure. (05 Mar 2000) |

| potassium succinate | A deliquescent powder used as a haemostatic. (05 Mar 2000) |
| potassium sulfate | K2SO4;an obsolete laxative. (05 Mar 2000) |
| potassium sulfocyanate | Formerly used in the treatment of essential hypertension and as a reagent in the detection of copper, iron, and silver. Synonym: potassium rhodanate, potassium sulfocyanate. (05 Mar 2000) |
| potassium tartrate | K2C4H4O6-1/2 H2O;a mild purgative and diuretic. Synonym: soluble tartar. (05 Mar 2000) |
| potassium thiocyanate | Formerly used in the treatment of essential hypertension and as a reagent in the detection of copper, iron, and silver. Synonym: potassium rhodanate, potassium sulfocyanate. (05 Mar 2000) |
| hydrogen-potassium-exchanging atpase | <enzyme> An enzyme isolated from the gastric mucosa that catalyses the hydrolysis of ATP coupled with the exchange of hydrogen and potassium ions across the cell wall. Chemical name: ATP phosphohydrolase (H+/K+-transporting) Registry number: EC 3.6.1.36 (12 Dec 1998) |
| sodium potassium ATPase | <enzyme> A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell and 2 potassium ions in, for each ATP hydrolysed. The sodium gradient established is used for several purposes (see facilitated diffusion, action potential), while the potassium gradient is dissipated through the potassium leak channel. Must not be confused with a sodium channel. (18 Nov 1997) |
| sodium-potassium-exchanging atpase | <enzyme> An enzyme that catalyses the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane atpase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients. Chemical name: ATP phosphohydrolase (sodium-potassium-transporting) Registry number: EC 3.6.1.37 (12 Dec 1998) |
| sodium-potassium pump | A membrane-bound transporter that maintains the high potassium and low sodium intracellular concentrations relative to the extracellular medium. This exchange is accomplished at the expense of cellular energy in the form of ATP. (05 Mar 2000) |
| sodium potassium tartrate | KNaC4H4O6;a mild saline cathartic, used as an ingredient in compound effervescent powders. Synonym: Rochelle salt, Seignette's salt, sodium potassium tartrate. (05 Mar 2000) |
| dibasic potassium phosphate | K2HPO4;a mild saline cathartic and diuretic. Synonym: dibasic potassium phosphate, dipotassium phosphate. (05 Mar 2000) |
| effervescent potassium citrate | A mixture of potassium citrate, citric acid, sodium bicarbonate, and tartaric acid; used as a gastric antacid and urinary alkaliser. (05 Mar 2000) |
| Luft's potassium permanganate fixative | A fixative useful in electron microscopy for cytologic preservation of lipoprotein complexes in membranes and myelin, because of its oxidative properties. (05 Mar 2000) |
| administration, oral | The giving of drugs, chemicals, or other substances by mouth. (12 Dec 1998) |
