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, essential for maintaining cellular membrane potential, nerve impulse transmission, and muscle contraction. Dextrose provides caloric supplementation.
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/h (using 0.11% potassium chloride in 5% dextrose), typically 10-20 mEq over 4-6 hours for mild hypokalemia, with a maximum concentration of 40 mEq/L via peripheral line.

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 homeostatically regulated; the terminal half-life of a potassium load is approximately 8-12 hours in healthy individuals, but this is highly variable and dependent on renal function, aldosterone status, and body stores. In anuric patients, potassium clearance is minimal, and dangerous accumulation can occur within hours.
Renal: >90% excreted unchanged in urine. Biliary/fecal: <5%.
Primarily renal; >90% of potassium is excreted by the kidneys, with approximately 10% lost in feces. In steady state, urinary potassium excretion matches dietary intake (typically 40-120 mEq/day). Dextrose is completely metabolized; unchanged dextrose excretion is negligible (<1% renal) in normoglycemic individuals.
