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 acetate provides potassium ions, which are essential for maintaining intracellular ionic balance, nerve conduction, muscle contraction, and acid-base equilibrium. It acts as a potassium replenisher and can also be used to alkalinize urine by converting to bicarbonate.
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.
Intravenous, 10-20 mEq/h, maximum infusion rate 20 mEq/h, not to exceed 150 mEq/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 not eliminated by first-order kinetics; plasma concentration reflects body stores and renal function.
Primarily renal (>80% as ionized calcium); minor fecal elimination (10-20%) via endogenous secretion; negligible biliary excretion.
Primarily renal (>90%) as potassium ions; minimal biliary/fecal.
