Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcium gluconate provides calcium ions, which are essential for normal cardiac function, nerve transmission, and muscle contraction. In hyperkalemia, calcium antagonizes the cardiotoxic effects of potassium by stabilizing the cardiac cell membrane.
Magnesium sulfate provides magnesium ions, which are essential for various physiological processes. It acts as a cofactor for enzymatic reactions, stabilizes excitable membranes, and antagonizes calcium entry at the neuromuscular junction, leading to reduced acetylcholine release and muscle relaxation. In the CNS, it may act as a noncompetitive antagonist of NMDA receptors, exerting anticonvulsant effects.
1-2 g calcium gluconate (9.3-18.6 mEq calcium) intravenously over 10-20 minutes, may repeat if needed. For continuous infusion: 0.5-2 mg/kg/hour calcium gluconate. Max rate: 1-2 mL/minute of 10% solution.
1 to 4 g intravenously as a 5% to 20% solution, rate not exceeding 150 mg/min; dosing frequency depends on indication (e.g., preeclampsia/eclampsia: 4-5 g IV loading then 1-2 g/hr infusion; hypomagnesemia: 1-2 g IV over 1-2 hours, may repeat based on serum magnesium levels).

Terminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment (up to 24-48 hours).
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Primarily renal; ~80% of administered calcium is excreted in urine via glomerular filtration with tubular reabsorption; fecal excretion accounts for ~15-20% as unabsorbed or secreted calcium; negligible biliary excretion.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
