Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium chloride dissociates to potassium ions, which are essential for maintaining intracellular tonicity, nerve impulse conduction, muscle contraction, and acid-base balance. Replacement therapy corrects hypokalemia and prevents potassium deficiency.
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. Replacement therapy corrects hypokalemia.
10-20 mEq/h IV, not exceeding 20 mEq/h; concentration ≤ 0.2 mEq/mL. Typical total daily dose 40-100 mEq, depending on serum potassium.
40 mEq orally once daily or divided every 6-12 hours; IV infusion at a rate not exceeding 10 mEq/hour with a maximum concentration of 40 mEq/L via peripheral line.

Not applicable (endogenous ion); distribution half-life ~1-1.5 h with normal renal function.
Potassium has no defined elimination half-life as it is a major intracellular ion tightly regulated by homeostatic mechanisms; serum levels reflect distribution and renal function. In anephric patients, the effective half-life is extended significantly.
Renal: >90% as potassium ions, with small fecal loss; no biliary elimination.
Renal: >90% of potassium is excreted by the kidneys. Approximately 80-90% of an oral dose is eliminated in urine, with the remainder in feces via intestinal secretion.
