Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcium chloride dissociates to provide calcium ions, which are essential for myocardial contractility, nerve impulse transmission, and blood coagulation. It antagonizes the cardiotoxic effects of hyperkalemia by stabilizing cardiac cell membrane potential.
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 every 1-3 days based on serum calcium levels.
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.

Terminal half-life ~4-6 hours for rapid distribution phase; prolonged in renal impairment (up to 24-48 hours).
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% as ionized calcium); minor fecal elimination (10-20%) via endogenous secretion; negligible biliary excretion.
Primarily renal (90%) as potassium ion; minimal fecal (<10%) and sweat.
