CALCIUM GLUCONATE IN SODIUM CHLORIDE vs MAGNESIUM SULFATE
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 acts as a physiological calcium channel blocker. It inhibits calcium influx into presynaptic nerve terminals, reducing acetylcholine release at the neuromuscular junction and decreasing muscle contraction. It also antagonizes NMDA receptors and stabilizes neuronal membranes.
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.
IV: Loading dose 4-6 g over 20-30 minutes, followed by maintenance infusion 1-2 g/hour for seizure prophylaxis in severe preeclampsia/eclampsia. IM: 4-8 g deep IM initially, then 4 g every 4 hours as needed.

Clinical Note
moderateTerminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment (up to 24-48 hours).
Terminal elimination half-life approximately 4-6 hours in patients with normal renal function; prolonged to 12-24 hours or more in renal impairment, necessitating dose adjustment
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 (90-95% as unchanged drug); minor biliary/fecal (<5%)
