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 principal intracellular cation and is essential for maintaining cellular membrane potential, nerve impulse transmission, and muscle contraction. Dextrose provides calories and may prevent ketosis.
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; typical adult dose is 10-20 mEq/hour, not exceeding 40 mEq/hour or 150 mEq/day, with continuous cardiac monitoring and serum potassium monitoring.

2-4 hours in patients with normal renal function; prolonged in renal impairment.
The elimination half-life of potassium is not applicable in the traditional sense because potassium is an endogenous ion under tight homeostatic control. After intravenous infusion of a potassium load, the plasma concentration declines with a distribution phase of about 1-2 hours, followed by a slower elimination phase reflecting cellular uptake and renal excretion, with a terminal half-life of approximately 6-8 hours in patients with normal renal function.
Primarily renal (80-90% as ionized calcium); minor fecal elimination (<10%).
Renal: >90% of potassium intake is excreted by the kidneys, primarily via distal tubular secretion; fecal: <10%; minor sweat losses. In this formulation (KCl 0.22% in D5W), the potassium content is 2 mEq per 100 mL (approximately 20 mEq/L).
