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 dissociates to potassium ions, which are essential for maintenance of intracellular tonicity, nerve impulse conduction, muscle contraction, and cardiac function.
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 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.

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.
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.
Primarily renal (90%), with fecal elimination accounting for approximately 10%. Excretion is via glomerular filtration, with tubular reabsorption and secretion adjusting potassium balance.
Primarily renal (90% excreted unchanged in urine); minor fecal elimination (<10%) via unabsorbed potassium.
