Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose (glucose) is a monosaccharide that serves as a substrate for cellular metabolism, providing energy and restoring blood glucose levels. Sodium chloride (0.45%) provides electrolytes and helps maintain osmolality; the hypotonic solution replaces fluid and electrolytes.
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.
Intravenous infusion; dose depends on fluid and electrolyte needs. Typical adult rate: 100-200 mL/hour (2-4 mL/kg/hour) for maintenance. Maximum infusion rate: 25 mL/kg/hour. Not to exceed 50 mL/kg/24 hours.
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
moderateThe terminal half-life of infused dextrose is not applicable as glucose is rapidly metabolized; however, exogenous glucose infusion is cleared with a half-life of approximately 15-30 minutes due to insulin-mediated uptake. Sodium and chloride have no defined elimination half-life as they are homeostatically regulated.
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
Dextrose is completely metabolized to carbon dioxide and water, with negligible renal excretion of intact glucose under normal conditions. Sodium and chloride are freely filtered by the glomerulus and undergo variable tubular reabsorption; excess is excreted renally. No biliary or fecal elimination.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
