Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcium ion is essential for normal cell function, including muscle contraction, nerve transmission, and blood coagulation. It acts as a positive inotrope by increasing myocardial contractility and also corrects hypocalcemia.
Potassium is the major intracellular cation, essential for maintaining cellular membrane potential, nerve impulse transmission, and muscle contraction. Dextrose provides caloric supplementation.
IV: 500 mg to 1 g (5-10 mL of 10% solution) administered slowly at a rate not exceeding 0.5-1 mL/min. May be repeated as needed based on serum calcium levels and clinical response.
Intravenous infusion at a rate not exceeding 10 mEq/h (using 0.11% potassium chloride in 5% dextrose), typically 10-20 mEq over 4-6 hours for mild hypokalemia, with a maximum concentration of 40 mEq/L via peripheral line.

2-4 hours in patients with normal renal function; prolonged in renal impairment.
Potassium has no true elimination half-life as it is homeostatically regulated; the terminal half-life of a potassium load is approximately 8-12 hours in healthy individuals, but this is highly variable and dependent on renal function, aldosterone status, and body stores. In anuric patients, potassium clearance is minimal, and dangerous accumulation can occur within hours.
Primarily renal (80-90% as ionized calcium); minor fecal elimination (<10%).
Primarily renal; >90% of potassium is excreted by the kidneys, with approximately 10% lost in feces. In steady state, urinary potassium excretion matches dietary intake (typically 40-120 mEq/day). Dextrose is completely metabolized; unchanged dextrose excretion is negligible (<1% renal) in normoglycemic individuals.
