Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Potassium chloride provides potassium ions for maintenance of electrolyte balance and cellular function; dextrose provides a source of calories and may stimulate insulin secretion, which facilitates intracellular potassium uptake; sodium chloride provides sodium ions for maintenance of fluid and electrolyte balance.
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.
Adult: Intravenous infusion at a rate determined by fluid and electrolyte needs; typical dose for maintenance is 1-2 L/day providing approximately 20-40 mEq potassium, 34-68 g dextrose, and 4-8 g sodium chloride per day. Administration rate not to exceed 10 mEq/h of potassium.

Clinical Note
moderateMagnesium sulfate + Gatifloxacin

Clinical Note
moderateMagnesium sulfate + Levofloxacin
"The serum concentration of Levofloxacin can be decreased when it is combined with Magnesium sulfate."
Clinical Note
moderateTerminal 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
Potassium: no defined terminal half-life due to tight homeostatic regulation; dextrose: minutes (insulin-mediated clearance); sodium: regulated by renal excretion.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Potassium is primarily excreted renally (90%) with minimal fecal loss; dextrose and sodium are fully metabolized or excreted renally.
