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 chloride dissociates to provide potassium ions, which are essential for maintaining intracellular tonicity, nerve impulse transmission, muscle contraction, and cardiac function. Dextrose provides a source of calories and may enhance cellular potassium uptake via insulin-mediated shift.
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; typical adult dose: 10-20 mEq per hour, not exceeding 40 mEq per dose and 200 mEq per day, titrated based on serum potassium and ECG monitoring.

2-4 hours in patients with normal renal function; prolonged in renal impairment.
The terminal elimination half-life of potassium is approximately 1-1.5 hours in individuals with normal renal function. This reflects rapid redistribution and renal clearance. In anephric or oliguric patients, half-life is prolonged significantly, leading to accumulation and risk of hyperkalemia. Dextrose has a half-life of 15-20 minutes due to rapid cellular uptake and metabolism.
Primarily renal (80-90% as ionized calcium); minor fecal elimination (<10%).
Renal excretion accounts for approximately 90% of potassium elimination, primarily via distal tubular secretion and reabsorption. Fecal excretion is minimal (<10%). The dextrose component is completely metabolized to CO2 and water, with no direct renal excretion.
