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, 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.
Potassium chloride dissociates into potassium ions, which are essential for maintaining cellular membrane potential, nerve impulse transmission, cardiac contractility, and acid-base balance. Replacement of potassium corrects hypokalemia.
10 mEq (1 tablet) orally once daily, titrated to serum potassium levels. Maximum 40 mEq per dose or 100 mEq per day.
20-40 mEq potassium chloride intravenously per dose, infused at a rate not exceeding 10 mEq/hour (or 20 mEq/hour in critical care settings), repeated as needed based on serum potassium levels. Maximum daily dose typically 200 mEq.

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.
Potassium chloride does not have a classic elimination half-life as it is an endogenous electrolyte. The terminal half-life of exogenous potassium is approximately 2-3 hours in healthy individuals, reflecting rapid cellular uptake and renal clearance. In renal impairment, half-life is prolonged.
Primarily renal (≥90% of absorbed potassium is excreted via kidneys; small amounts lost in feces and sweat).
Renal excretion is the primary route; >90% of potassium is excreted by the kidneys, with a small amount lost in feces (via gastrointestinal secretion) and negligible biliary excretion. Renal elimination is regulated by aldosterone and tubular secretion.
