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, transmission of nerve impulses, contraction of cardiac, skeletal, and smooth muscle, and maintenance of normal renal function. Potassium chloride dissociates to provide potassium ions and chloride ions. Potassium repletion corrects hypokalemia and associated disorders.
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.
Oral: 40-100 mEq/day in divided doses; IV: up to 10-20 mEq/hour via central line, max 40 mEq/hour with continuous monitoring; not to exceed 200 mEq/day.

2-4 hours in patients with normal renal function; prolonged in renal impairment.
Not applicable; potassium is an electrolyte regulated by homeostasis, not classic elimination half-life. Under normal renal function, serum half-life of administered potassium is approximately 2-4 hours due to rapid cellular uptake and renal excretion.
Primarily renal (80-90% as ionized calcium); minor fecal elimination (<10%).
Primarily renal (90%) as potassium ion; minimal fecal (<10%) and sweat.
