| potassium bromide | KBr;an obsolescent sedative and hypnotic (sodium bromide is usually preferred). (05 Mar 2000) |
| potassium channel | Ion channel selective for potassium ions. There are diverse types with different functions, for example: delayed rectifier channels, M channels, A channels, inward rectifier channels, Ca dependent K channels. (18 Nov 1997) |
| potassium channels | Cell membrane glycoproteins selective for potassium ions. (12 Dec 1998) |
| potassium chlorate | Chlorate of potash, KClO3, used as a mouthwash and gargle in stomatitis and follicular pharyngitis; it is incompatible in the dry state with all easily oxidizable substances. (05 Mar 2000) |
| potassium chloride | <chemical> Potassium chloride. A white crystal or crystalline powder used as an electrolyte replenisher, in the treatment of hypokalaemia, in buffer solutions, and in fertilisers and explosives. Chemical name: Potassium chloride (KCl) (12 Dec 1998) |
| potassium citrate | <chemical> A systemic alkaliser, electrolyte replenisher, diuretic, and expectorant, usually administered orally. It is sometimes used in veterinary medicine as a nonirritating diuretic. Pharmacological action: diuretics, expectorants. (12 Dec 1998) |
| potassium compounds | Inorganic compounds that contain potassium as an integral part of the molecule. (12 Dec 1998) |
| potassium cyanide | <chemical> Potassium cyanide (k(cn)). A highly poisonous compound that is an inhibitor of many metabolic processes, but has been shown to be an especially potent inhibitor of haem enzymes and haemproteins. It is used in many industrial processes. Pharmacological action: enzyme inhibitors, poisons. Chemical name: Potassium cyanide (K(CN)) (12 Dec 1998) |
| potassium deficiency | A condition due to decreased dietary intake of potassium, as in starvation or failure to administer in intravenous solutions, or to gastrointestinal loss in diarrhoea, chronic laxative abuse, vomiting, gastric suction, or bowel diversion. Severe potassium deficiency may produce muscular weakness and lead to paralysis and respiratory failure. Muscular malfunction may result in hypoventilation, paralytic ileus, hypotension, muscle twitches, tetany, and rhabomyolysis. Nephropathy from potassium deficit impairs the concentrating mechanism, producing polyuria and decreased maximal urinary concentrating ability with secondary polydipsia.
