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.
Sodium acetate provides sodium ions and acetate ions. Acetate is metabolized to bicarbonate, which acts as a buffer to correct metabolic acidosis.
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: 50-200 mL of 0.1-0.4 mEq/mL solution per dose; administer at a rate not exceeding 1 mEq/kg/hour; frequency based on serum bicarbonate and acid-base status.

Terminal half-life ~4-6 hours for rapid distribution phase; prolonged in renal impairment (up to 24-48 hours).
2-3 minutes (rapid conversion to bicarbonate in circulation). Clinical context: Exogenous acetate (e.g., in parenteral nutrition) is quickly cleared, limiting duration of alkalinizing effect.
Primarily renal (>80% as ionized calcium); minor fecal elimination (10-20%) via endogenous secretion; negligible biliary excretion.
Primarily renal; acetate is rapidly metabolized to bicarbonate via the Krebs cycle, with less than 5% excreted unchanged in urine.
