Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium ion replacement; essential for maintenance of intracellular tonicity, nerve impulse transmission, cardiac and skeletal muscle contraction, and acid-base balance.
Potassium is the major intracellular cation; it is necessary for conduction of nerve impulses, contraction of cardiac, skeletal, and smooth muscle, maintenance of normal renal function, acid-base balance, and carbohydrate metabolism.
IV: 10 mEq potassium chloride infused at a rate not exceeding 10 mEq/hour via peripheral line; maximum 20 mEq/hour via central line with continuous ECG monitoring. Oral: 20-40 mEq per day in divided doses; maximum 100 mEq per day.
Oral: 15 mEq (1 tablet) once daily or as directed; range 15-100 mEq/day divided doses. Maximum 150 mEq/day.

Potassium does not have a true elimination half-life as it is an endogenous ion under homeostatic control. However, intravenously administered potassium has a distribution half-life of approximately 1-1.5 hours and a slow terminal phase reflecting cellular redistribution and eventual excretion. Clinical context: The apparent half-life is highly dependent on renal function and body stores.
Not applicable; potassium is not eliminated by first-order kinetics. Serum potassium decline depends on redistribution and renal function, with a half-life of approximately 1-1.5 hours for acute redistribution but prolonged in renal impairment.
Potassium is primarily excreted via the kidneys (approximately 90%) with the remainder lost in feces (via colonic secretion). In patients with normal renal function, urinary potassium excretion accounts for >90% of elimination. Fecal excretion is minimal (≤10%) but increases in renal impairment.
Renal: >90% as potassium ions; fecal: <5%; biliary: negligible.
