Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcium gluceptate is a calcium salt that dissociates to provide calcium ions, which are essential for various physiological processes including nerve conduction, muscle contraction, blood coagulation, and cardiac function. It acts as a calcium replenisher.
Potassium is the major intracellular cation. It is essential for the maintenance of intracellular tonicity, nerve impulse transmission, cardiac muscle contractility, and skeletal muscle contraction. Dextrose provides a source of calories and may help to correct hypoglycemia.
IV: 2-4 mg/kg elemental calcium (5-10 mL of 0.45 mEq/mL solution) administered slowly over 10-20 minutes. May repeat if needed. Maximum dose: 20 mL per infusion.
Intravenous infusion at a rate not exceeding 10 mEq/hour (0.75 mEq/kg/hour). Typical dose: 20-40 mEq potassium chloride in 1 liter D5W administered over 8-12 hours.

Terminal elimination half-life: 2-4 hours (normal renal function); prolonged to 12-24 hours in renal impairment.
Potassium has no true elimination half-life as it is an endogenous electrolyte; redistribution half-life is approximately 1–1.5 hours for exogenous loads, reflecting cellular uptake and renal excretion. In anephric patients, half-life extends to 12–24 hours due to reliance on gastrointestinal and dialysis excretion.
Renal: >90% excreted unchanged in urine. Biliary/fecal: <5%.
Renal: >90% of potassium excreted by kidneys, with distal tubular secretion and reabsorption. Fecal: ~10% eliminated via gastrointestinal tract. Biliary: negligible.
