Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium is the major intracellular cation. It is essential for the maintenance of intracellular tonicity, nerve impulse transmission, cardiac muscle contractility, and skeletal muscle contraction. Dextrose provides a source of calories and may help to correct hypoglycemia.
Potassium is the major intracellular cation. It is essential for the maintenance of intracellular tonicity, transmission of nerve impulses, contraction of cardiac, skeletal, and smooth muscle, and maintenance of normal renal function. Potassium chloride dissociates to provide potassium ions and chloride ions.
Intravenous infusion at a rate not exceeding 10 mEq/hour (0.75 mEq/kg/hour). Typical dose: 20-40 mEq potassium chloride in 1 liter D5W administered over 8-12 hours.
10 mEq (1 tablet) orally once daily, titrated to serum potassium levels. Maximum 40 mEq per dose or 100 mEq per day.

Potassium has no true elimination half-life as it is an endogenous electrolyte; redistribution half-life is approximately 1–1.5 hours for exogenous loads, reflecting cellular uptake and renal excretion. In anephric patients, half-life extends to 12–24 hours due to reliance on gastrointestinal and dialysis excretion.
Not applicable as potassium is an electrolyte; its elimination follows first-order kinetics with a terminal half-life of approximately 2–3 hours in healthy individuals, reflecting rapid redistribution and renal clearance.
Renal: >90% of potassium excreted by kidneys, with distal tubular secretion and reabsorption. Fecal: ~10% eliminated via gastrointestinal tract. Biliary: negligible.
Primarily renal (≥90% of absorbed potassium is excreted via kidneys; small amounts lost in feces and sweat).
