Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium chloride (KCl) replaces potassium ions, which are essential for maintaining cellular membrane potential, nerve impulse transmission, muscle contraction, and acid-base balance. Dextrose 5% provides a source of calories and water for hydration.
Potassium chloride dissociates to potassium ions, which are essential for maintenance of intracellular tonicity, nerve impulse conduction, muscle contraction, and cardiac function.
10-20 mEq potassium chloride IV infused at a rate not exceeding 10-20 mEq/hour; maximum 40 mEq per dose. Administer in dextrose 5% solution.
10-20 mEq intravenously over 1 hour, not exceeding 10 mEq/hour or 200 mEq per day; oral dosing for hypokalemia: 20-40 mEq 2-4 times daily.

Potassium has no classic elimination half-life; distribution and excretion are rapid with a plasma half-life of approximately 1–1.5 hours in healthy individuals, but this is clinically irrelevant as body stores are regulated by renal function.
No classical terminal half-life; plasma potassium is rapidly regulated by cellular uptake and renal excretion, with equilibration half-life of ~1-2 hours in normal renal function.
Renal: >90% of potassium is excreted renally, primarily via distal tubular secretion; a small fraction is lost in feces (<10%) and negligible biliary elimination.
Primarily renal (90% excreted unchanged in urine); minor fecal elimination (<10%) via unabsorbed potassium.
