CALCIUM CHLORIDE 10% vs POTASSIUM CHLORIDE 10MEQ
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.
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.
10 mEq (1 tablet) orally once daily, titrated to serum potassium levels. Maximum 40 mEq per dose or 100 mEq per day.

Terminal half-life ~4-6 hours for rapid distribution phase; prolonged in renal impairment (up to 24-48 hours).
Not applicable as potassium is an electrolyte; its elimination follows first-order kinetics with a terminal half-life of approximately 2–3 hours in healthy individuals, reflecting rapid redistribution and renal clearance.
Primarily renal (>80% as ionized calcium); minor fecal elimination (10-20%) via endogenous secretion; negligible biliary excretion.
Primarily renal (≥90% of absorbed potassium is excreted via kidneys; small amounts lost in feces and sweat).
