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 phosphates act as a source of phosphate and sodium ions. Phosphate is an essential component of bone mineral, cell membranes, and energy metabolism. It also acts as a buffer in acid-base balance. In the gastrointestinal tract, hyperosmotic sodium phosphate solution draws water into the lumen, inducing bowel evacuation.
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: 3.75-7.5 g (15-30 mmol phosphate) 1-4 times daily. IV: 0.3-0.5 mmol/kg over 6-12 hours.

Terminal half-life ~4-6 hours for rapid distribution phase; prolonged in renal impairment (up to 24-48 hours).
Not applicable; phosphate is an endogenous ion with rapid equilibration. Serum phosphate half-life is approximately 30 minutes due to renal clearance and cellular uptake.
Primarily renal (>80% as ionized calcium); minor fecal elimination (10-20%) via endogenous secretion; negligible biliary excretion.
Renal: >90% of absorbed phosphate is excreted renally, primarily as inorganic phosphate; fecal elimination accounts for <10%.
