Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium is the major intracellular cation, essential for maintenance of normal cell function, nerve impulse transmission, and muscle contraction. Replacement therapy restores potassium levels in hypokalemia.
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.
20 mEq intravenously over 1 hour, repeated as needed based on serum potassium levels. Maximum infusion rate 10 mEq/hour. Maximum daily dose 200 mEq.
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.

Not applicable as potassium is an endogenous ion; however, the biological half-life for serum potassium redistribution and excretion is approximately 1-1.5 hours in individuals with normal renal function. In renal impairment, half-life may be prolonged and requires dose adjustment.
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.
Primarily renal (90%), with fecal elimination accounting for approximately 10%. Excretion is via glomerular filtration, with tubular reabsorption and secretion adjusting potassium balance.
Renal: >90% of potassium is excreted renally, primarily via distal tubular secretion; a small fraction is lost in feces (<10%) and negligible biliary elimination.
