Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Magnesium sulfate causes decreased release of acetylcholine at the neuromuscular junction, reducing muscle contractility. It also blocks calcium channels, leading to vasodilation and anticonvulsant effects.
Nicardipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It has greater selectivity for vascular smooth muscle than for cardiac muscle, leading to vasodilation and reduced peripheral vascular resistance. It does not significantly affect sinoatrial nodal or atrioventricular conduction.
IV: 1-4 g as a 10-20% solution, rate not exceeding 1 g/min; for eclampsia: 4-5 g IV bolus then 1-2 g/hour IV infusion.
Administer intravenously at an initial rate of 5 mg/h, titrated by increasing by 2.5 mg/h every 5-15 minutes to a maximum of 15 mg/h for hypertension. For substitution of oral therapy, start at 0.5 mg/h and titrate to achieve desired blood pressure.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Terminal elimination half-life is 8.6 hours (range 6-10 hours) in adults with normal hepatic function; prolonged in elderly or hepatic impairment. Clinical context: permits continuous IV infusion for stable hemodynamic control.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Primarily hepatic metabolism (>90%) with <1% unchanged drug excreted renally. Fecal excretion accounts for approximately 35% of metabolites via biliary elimination.
