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 essential for the maintenance of intracellular tonicity, transmission of nerve impulses, contraction of cardiac, skeletal, and smooth muscle, and maintenance of acid-base balance. Potassium replacement therapy corrects hypokalemia.
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.
20 mEq potassium chloride orally once daily, adjusted based on serum potassium levels and patient response. Maximum rate of administration: 20 mEq per hour if intravenous; oral doses divided if >20 mEq per dose.

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.
The terminal elimination half-life of potassium is approximately 8-12 hours in healthy individuals, but is 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.
Potassium is primarily excreted renally (approximately 90%) as potassium ion in urine. A small amount is excreted in feces (about 10%).
