Mechanism of Action

Cardene (nicardipine) is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle, leading to vasodilation and reduced afterload.

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.

Clinical Dosing

Intravenous infusion: Initial dose 5 mg/hour, titrate by 2.5 mg/hour every 5 minutes as needed to maximum 15 mg/hour. For maintenance, reduce to 3 mg/hour after blood pressure controlled. Label strength: 0.1 mg/mL in 0.86% NaCl.

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).
