Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium is the major intracellular cation; it is essential for maintenance of intracellular tonicity, transmission of nerve impulses, contraction of cardiac, skeletal, and smooth muscle, and maintenance of normal renal function. Potassium chloride dissociates in solution to provide potassium ions and chloride ions.
Potassium chloride dissociates to potassium ions, which are essential for maintenance of intracellular tonicity, nerve impulse conduction, muscle contraction, and cardiac function.
40 mEq intravenously over 4-6 hours, as needed. Maximum infusion rate: 10 mEq/hour, maximum concentration: 40 mEq/L.
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; potassium is a physiologic ion without classic elimination half-life. Steady-state distribution occurs within 6-8 hours of continuous infusion. Clinical context: half-life of potassium is determined by cellular uptake and renal excretion, with rapid redistribution in hypokalemic states.
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% as potassium ion, with minimal biliary or fecal elimination (less than 10% total).
Primarily renal (90% excreted unchanged in urine); minor fecal elimination (<10%) via unabsorbed potassium.
