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. It is essential for the maintenance of intracellular tonicity, nerve impulse transmission, cardiac muscle contractility, and skeletal muscle contraction. Dextrose provides a source of calories and may help to correct hypoglycemia.
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/hour (0.75 mEq/kg/hour). Typical dose: 20-40 mEq potassium chloride in 1 liter D5W administered over 8-12 hours.

2-4 hours in patients with normal renal function; prolonged in renal impairment.
Potassium has no true elimination half-life as it is an endogenous electrolyte; redistribution half-life is approximately 1–1.5 hours for exogenous loads, reflecting cellular uptake and renal excretion. In anephric patients, half-life extends to 12–24 hours due to reliance on gastrointestinal and dialysis excretion.
Primarily renal (80-90% as ionized calcium); minor fecal elimination (<10%).
Renal: >90% of potassium excreted by kidneys, with distal tubular secretion and reabsorption. Fecal: ~10% eliminated via gastrointestinal tract. Biliary: negligible.
